Who We Are:

Ethena Labs is at the forefront of the next wave of DeFi, dedicated to building products for modern finance. Ethena is a synthetic dollar protocol built on Ethereum that provides a crypto-native solution for money, USDe, alongside a globally accessible dollar savings asset, sUSDe.

Our core mission is to provide truly crypto-native financial solutions that are globally accessible and bridge the gap between TradFi and the digital asset economy. We believe in transparency, efficiency, and empowering both individuals and institutions with greater control over their assets.

What we are Doing:

Ethena Labs is actively building and deploying a suite of groundbreaking products designed to address key challenges and unlock new opportunities within the digital finance landscape.

Our flagship product, USDe, is a synthetic dollar backed by digital assets, and takes the novel approach of using a delta-neutral hedging strategy to maintain its peg. This provides a truly scalable and censorship-resistant digital dollar.

Building upon USDe, we offer sUSDe. sUSDe provides crypto-native rewards generated from funding rates in derivatives markets, offering an alternative to existing products tethered to the traditional financial system.

Furthermore, we are actively developing solutions to facilitate institutional adoption of digital assets. In partnership with Securitize and Blackrocks BUIDL fund, USDtb provides a more traditional, asset-backed stablecoin option, leveraging established financial infrastructure to appeal to institutional clients. Expanding on this, iUSDe is designed specifically for traditional financial institutions, incorporating necessary compliance features to enable them to access the crypto-native rewards our protocol generates, in an institutional-friendly manner.

Finally, our most ambitious undertaking to date is Converge, our joint blockchain initiative with Securitize. This hybrid blockchain is designed to be the nexus where DeFi meets the needs of CeFi and TradFi. Converge aims to be a primary issuance layer for tokenised assets, integrating seamlessly with existing DeFi protocols to provide institutions with an environment to participate in the decentralised economy.

Through these offerings, Ethena Labs is not just creating new financial products; we are building the foundational infrastructure for a more open, efficient, and interconnected global financial system.

You will provide guidance to the community and solve their struggle, working on one of the most popular React UI library.

Details of the role

Location: Remote (preference for UTC-6 to UTC+5).
Type of work: Full-time (contractor or employee depending on circumstances).
Level: IC4 or above.
We're a remote company, we prefer asynchronous communication over meetings.

The company

MUI's story began in 2014 with Material UI, the most successful React implementation of Google's Material Design. Today, Material UI stands as one of the most popular open-source libraries on GitHub and has paved the way for the fully-fledged startup known as MUI (founded in 2019), which now boasts an ever-expanding ecosystem of React UI products. We're a company of 35+ people as of early 2025, and we're growing.

The products

MUI is best known for our flagship product, Material UI—but this is just one of three core component libraries we maintain. Base UI is our headless component library, and Pigment CSS is a zero-runtime CSS-in-JS styling engine. We also host Design Kits and pre-built Templates.

Beyond the core libraries, MUI X offers advanced components like the Data Grid, Date and Time Pickers, and Charts, for more complex user interactions and data visualization needs.

Learn more about MUI's products in this blog post: An introduction to the MUI ecosystem.

The culture

MUI is a fully remote company with a team that spans across the globe. The majority of our work is asynchronous, and we rely mostly on written communication to collaborate. We're radically transparent: nearly all of our work happens in public. Each contributor has the freedom to decide how and when they work, and that work is primarily self-directed: it's your responsibility to define and complete your own tasks in a timely manner.

For additional details about the culture, you can check our careers and about pages and also our public Handbook.

Why we're hiring

We need a Community Engineer to solve friction points of users. We face challenges on multiple fronts:

As the library grows, we (will) have more users questions and feedback coming in than ever before.
The rapid growth of new products is stretching our developers too thin.
Software engineers at MUI are tasked with doing support, however, they could benefit from the help of a dedicated person per project, for instance to improve the workflows and tooling.

Overall, both our open-source community and our premium products are growing fast. We need talented people to keep up with the demands of our exigent community!

The role

Why this is interesting

You will be a key member of the Core team and will directly impact the project's roadmap. You will troubleshoot and depending on your bandwidth also fix complex issues related to MUI. At MUI a Community Engineer is considered a developer, it's a person that enjoys optimizing what already exists but is also eager to help our users with features that are requested by the community.

Our products empower React developers to build awesome applications faster – we see millions of developers on MUI's docs every year, one million a month.

Key responsibilities

You will own the following responsibilities:

Build product knowledge. You will continually research and learn the current and future best practices of using MUI.
Resolve users' issues. You will solve these issues at two levels:
On the surface, you will answer developers on GitHub.
At the root, you will create/update the documentation, fix bugs, implement community driven features and more.
Provide feedback. You will work alongside product managers to define and shape the product goals, roadmap, priorities, and strategy based on your frontline knowledge of customer needs.
Operations.
You will establish key support metrics and identify how best to measure them.
You will establish a workflow to reduce 'time to response' and 'time to fix' that can scale to multiple team members.
You will identify where internal tooling might be developed or obtained to improve support efficiency.

Depending on the day, you'll:

Interact with the users on a regular basis, handling inbound support and feature requests (every developer helps with developer requests).
Reduce friction. A large amount of the work on MUI is reducing friction and making it easier to use. This might involve careful API design, identifying and fixing top bugs, creating easier-to-understand error messages, and writing documentation and blog posts about features you ship.
Collaborate with the community. Many small, as well as meaningful fixes and features, have been contributed by the community. Your role is to draw the best out of the community — to inspire those across the world to create and contribute through your reviews of their issues and pull requests.
Experiment and play. Great, unexpected features and heisenbug fixes have come from a number of sources — relentlessly methodical processes of elimination, free-flowing team collaboration, inspiration by adjacent libraries and projects, and difficult-to-explain individual strokes of brilliance. Whatever your preferred style is for creating new things that others might not have thought of, you'll find a welcome home on the team.
Ship. Early and often. You'll iterate and ship frequently. You'll have a real impact on the end-user experience and you'll love working on a team that builds stunning UIs and prioritizes delivering real user value as often as possible.

Who we're looking for

We're looking for someone with strong front-end skills. More important than specific technical skills though is that you're a strong problem solver who loves to learn. Details matter to you.

Required

Expertise in the modern JavaScript ecosystem. MUI's open-source projects are built on the shoulders of giants, making use of technologies such as ES2021, TypeScript, Node.js, React, Next.js, webpack, and Babel.
A track record of demonstrating an eye for product and solving real-world user problems. If you have a knack for solving problems at the root cause, shipping beautiful user interfaces and intuitive APIs, we want you on our team.
Strong written and verbal communication skills. As part of the team, you'll interface both directly and indirectly with community members and enterprise customers, and contribute to user documentation. Clear communication is fundamental in creating intuitive and compelling resources.
Ability to dive into complex problems. You should be able to quickly assess, understand, and iterate upon aspects of our codebase.
Ready and willing to ask and answer questions. If you're comfortable saying you're unsure, asking for help; but equally reaching out to assist others, you'll be an incredible addition to our team. We thrive because of continuous learning. First-time mistakes should be celebrated, not blamed.
Avoid monolithic deliverables. You scope and stage your work into well-defined milestones to ship.
Past work with front-end infrastructure. Perhaps you've created your company's design system, written a Babel plugin, or written complex React components. It would be great if you could address this in your cover letter!
You've contributed to a design system before. You have worked on enterprise components in the past, maybe for internal use in your company. You have built complex and advanced features while making sure the accessibility was fully functional.

Nice to have (but not required)

You've maintained an active repository before. Maybe you've helped maintain a popular open-source repository, or perhaps you've worked on internal repositories that saw contributions from multiple teams. Previous experience with highly active repository workflows is a definite plus for this role.
You have contributed code. A history of contributing to MUI's open-source projects is a plus.

Benefits and compensation

Competitive compensation depending on the profile and location. We are ready to pay top market rates for a person who can clearly exceed the role's expectations. You can find the other perks & benefits on the careers page.

How to apply

Don't meet every requirement? Apply anyway! Research shows that certain folks are less likely to apply for a role than others unless they meet 100% of the outlined qualifications. If this role excites you, we want to hear from you. We'd love for you to share the unique skills, passion, and experience you could bring to MUI.

Rayon’s mission

Rayon is building the next generation of architectural design software. More collaborative, simpler, smarter and more beautiful.
The design of building and spaces has a huge impact on our lives. Climate change, affordable housing, sustainable urbanization, future of work : all of these challenges will require us to design a better and more efficient built environment.
But, whereas architectural design is by essence a collaborative endeavor, the tools currently used by architects and designers are not made for collaboration and sharing knowledge. They are complex, they are expensive and they are stuck in an era pre-internet with desktop computers as their paradigm.
We are building a browser based collaborative real time multiplayer editor in order to democratize architectural design and empower designers to create more efficient spaces and buildings.

Who are we ?

We are a small team of 15 people passionate about web technology, architecture, and the built environment. First and foremost, we love building amazing tools for creators.
Rayon was co-founded in October 2021 by Bastien Dolla, an engineer (Polytechnique & Ponts et Chaussées) with 15 years of experience in tech and real estate, and Stanislas Chaillou, an engineer and an architect (EPFL & Harvard) with a background in ML research applied to architecture.
**Rayon recently raised a €4million** Seed round, backed by world-class Investors (Northzone, Foundamental, Seedcamp, 20VC, Kima) and amazing business Angels such as Ralph Gootee, co-founder of plangrid (acq. by Autodesk), Joe Thomas co-founder and CEO of Loom , the architect Norman Foster (Foster+Partners), Rasmus Andersson (ex-Spotify, ex-Meta), Thibaud Elziere founder of eFounders, Nicolas Steegmann co-founder of Stupeflix, Riggs Kubiak founder of Honest buildings (acq. Procore), Jonathan Widawski founder & CEO of Maze.
Rayon is a French company based in Paris. We are open to remote positions in time zones close to European Central Time.

What you will be doing

As rust software engineer, you will :

Work closely with the rest of the engineering team and product team to contribute to the development of Rayon web application
Be in charge of maintaining and improving Rayon’s rust engine : including its geometric kernel and webgl renderer.

What are we looking for ?

💡 These points are here to give you an idea of what we think would be a good fit for the job. They are not hard requirements. If you do not fit them perfectly but feel like you would do the job well, do not hesitate to contact us !

First and foremost a passion for creating tools for creator with the highest quality and performance
A love for highly performant and well crafted applications
The ability and the desire to continually learn new things and improve
2+ years experience in rust software development. A direct experience in game development, the creation of a real time multiplayer tool or a web design tool is a bonus.
A very good knowledge of rust and webassembly development (wasm-bindgen, wasm-pack). A good knowledge of the ECS architecture (specs, bevy, legion). A good knowledge of computer graphics, in particular webgl. Additional experience in web development (Typescript, React, websocket) is a bonus.
A prior startup experience is recommended
Interest or past experience with architectural or interior design projects is a bonus

Why should you join Rayon ?

Help create a product that has the potential to profoundly change for the best how our built environment is designed and that can help spread architectural knowledge throughout the world.
Be part of a small team of passionate members whose culture puts the highest value on design and engineering craftmanship.

Competitive compensation and significant equity upside as one of Rayon first team members

What’s our process ?

Send an email at bastien@rayon.so (even if you’re afraid your profile does not perfectly fit, do it anyway !)
We’ll do a first 30 min call to get to know each other
We’ll then do a more technical interview, where we can explore some of your personal projects or work on a problem together. This will also be the opportunity for you to quizz us on rayon’s stack
A longer call (if possible IRL) with both co-founders to talk about vision and company culture
That’s it. You’ll get an offer if it’s a fit !

Creator Empathy: You genuinely understand and care about solving problems for content creators because you either are one (with 500+ followers/subscribers) or have experience working closely with them.

Why vidIQ

Impact: Build products that impact millions of creators globally, directly contributing to their success.

Communication Stipend: Enjoy a monthly stipend to cover your phone and internet expenses, helping you stay connected effortlessly.
Global Impact: Join our diverse team that’s shaping the future of the creator economy across the globe.

Compensation

This is a remote position open to candidates worldwide. Employment classification and engagement structure will be determined based on location, legal requirements, and mutual fit.

Our compensation structure includes competitive project-based or monthly rates and, where applicable, stock option grants. The broad compensation range reflects our openness to engaging talent across different seniority levels—from Associate to Staff. Your exact rate will be determined based on your experience, skills, and level, as well as current market benchmarks.

The base compensation range for this role is $90,000 – $270,000 annually (pro-rated based on contract terms).

About Aios Medical

Our overarching mission is to accelerate the mass-market adoption of consumer biotech products so every human can live at least 100 healthy years. Our immediate focus is excess bodyweight. We are increasing the accessibility of GLP-1 medications to accelerate their take-up to help solve obesity worldwide.

To do that, we’re building an AI-powered clinical operating system: ClinicOS. ClinicOS makes it effortless for consumer brands to easily offer direct-to-patient healthcare, globally. We work with external Brand Partners, as well as using this infrastructure to scale our own internal consumer healthcare brands.

Since we launched Fella Health in the US in June 2021, Fella has positioned itself as no-nonsense weight loss for busy bigger guys. Today, we operate multiple brands across the US & UK — our two biggest are Fella Health (US & UK) & Bolt Pharmacy (UK).

Our infrastructure will have served 100 million patients worldwide by 2035. We’ll then use that direct-to-patient infrastructure to serve next-gen biotech products at-scale to increase the proportion of humans living at least 100 healthy years.

In so doing, we’ll become the world’s first trillion dollar healthcare company.

How far along are we?

We’ve grown >2000x since Aug 2021, >200x since Aug 2022, >20x since Aug 2023. We’re >$50M/yr revenue. We’ve been cashflow positive since June 2023. We’re >10,000 customers with high NPS.

We’re a young startup and we’re just getting started. This is still Day 1 and all our work is ahead of us.

We're backed by top healthcare & consumer investors:

Y Combinator
Global Founders Capital — backed Facebook, Slack, LinkedIn, Revolut, Rocket Internet
AngelList Early Stage Fund (backed by Naval Ravikant)
BrandProject (venture-builder behind 2 unicorns)
The founders of Indeed, Curative (unicorn), Alan (unicorn), Kaia Health (>$300mil valuation), Vouch Insurance (>$500mil valuation), Not Boring (Packy McCormick)

Being an Analytics Engineer at Aios Medical

Aios Medical is building a world-class team.

As Senior Analytics Engineer, your fundamental role is to take full ownership of our data stack, building reliable pipelines, making data accessible across all teams, and setting the foundations for a future centralized data team.

You’ll start within the engineering team, focused on optimizing current systems and setting up what’s missing: rebuilding our pipelines, building ETL jobs that sync our sources to the data warehouse, setting up dbt transformations, and making sure things run smoothly.

You’ll make high-impact decisions on tooling, sync frequency, and error handling so the data just works.

At the same time, you'll help define how we measure our business across the full customer journey: pre-conversion (e.g. CAC, CPL) and post-conversion (e.g. time to medication). You'll work directly with Ben and Dave to identify what metrics matter most, then build the systems and logic to track them. You'll be both engineer and analyst: making data accessible, and making it meaningful.

Great performance in this role means the pipelines are stable, reporting is self-serve, and we’ve laid the groundwork for a centralized data team that can scale. You’ll be the one who gets us there.

This is a full-time, fully remote role, and you’ll work async in the timezone of your choice as long as you’re around until midday Pacific Time for calls as needed.

You’ll report directly to Gzim (Head of Engineering). You’ll also work closely with: Ben (Head of Product) & Dave (Head of Growth).

Key Responsibilities

You’ll be the go-to person for all things data at Aios. You’ll fix what’s broken, build what’s missing, and soon build the foundation for a horizontal data team.

Build Stable ETL: Our current syncs aren’t as reliable as they should be. You’ll own the flow of data from 20+ sources into Redshift, reducing manual checks, fixing failure points, and making sure everything runs smoothly day to day.
Engineering Heavy: You'll spend significant time on data engineering fundamentals: warehouse architecture, dbt transformation logic, pipeline tooling, and all the technical decisions that keep data flowing reliably.
Analytics: You’ll support both sides of the business: Growth (e.g. CAC, CPL, funnel metrics) and Product/Ops (e.g. time to medication, delivery times). You’ll stitch the data together so these metrics are clean and trusted.
Solo Operator: This is a senior role. You won’t wait to figure things out. You know what matters, how to define it, and how to build the backend logic to track it.
Strategic Partner: You’ll become a key decision-maker on data across the org, balancing reliability, speed, and clarity in how we use data to drive the business.

Need to Have

Experience: You’ve worked with data for 5+ years and have at least 3+ years focused on data engineering. You’ve owned pipelines, warehouses, and reporting in fast-moving environments.
Data Engineering: You’ve built and maintained data pipelines that sync from multiple sources into a central warehouse like Redshift. You’ve set up syncing logic, error handling, and you know what breaks &how to fix it.
Data Models and Querying: You can write and debug complex SQL queries, optimize for performance, work with large datasets, and build reusable data models. You're comfortable with both ad-hoc analysis and production transformation
Metric Clarity: You understand what the business is trying to measure. If someone asks for CAC or time to medication, you know how to break that down into the data points required, find the right source, and build it end to end.
Ownership: You don’t need someone to tell you what to build. You’ll figure out what matters, how to define it, and how to track it both for pre and post-conversion journeys.
Autonomy: You’ve worked as a solo operator or early hire before. You know how to prioritize, unblock yourself, and move fast without waiting on others.
Team Builder: You’ve managed a team before. You’re excited to grow a team around you to cover both data engineering and analytics as the function scales.

Nice to Have

Growth Metrics: You’ve supported teams measuring CAC, CPL, funnel stages, or other acquisition metrics. You can speak the same language as growth leads and turn ideas into dashboards.
Clinical/Product Metrics: You’ve worked with operational metrics in healthcare or similar industries (e.g. fulfillment speed, delivery time).
Analytics Tools: You’ve used tools like Metabase or similar to help teams explore data, visualize results, and share reports.
Rudderstack: You’ve worked with customer data platforms like Rudderstack, and understand how to manage event tracking and integrations.
Figure it out: You’re the kind of person who doesn’t stop at “why is this broken?”you dig until it works. You can debug a failing sync, validate weird numbers, or reverse engineer a broken report.

Our cultural standards

These are the core cultural standards to which we hold ourselves & our team-members at Fella:

These are the core cultural standards to which we hold ourselves & our team-members:

Belief in the mission: We will have served 100 million patients by the end of 2035 and we transform the life of most patients who join. We have a lot of work to do. We are obsessed with our patients and are dedicated to the mission.
Unwavering integrity: We are at the frontier, so we often live in ambiguity with no trodden path. When we can’t look to others for guidance, we must maintain impeccable ethics and unwavering integrity.
Only the paranoid survive: Bad sh*t is coming. By joining us, you’re choosing to sail straight towards the storms with unhesitating conviction. However much we’ve already done, however far we’ve already come — it’s still Day 1 and all our work is ahead of us.
If we’re average we fail: We are only interested in “insanely great”, a focus on the quality of our execution that in everyday life would be considered pathological. We have a dedication to excellence and reject incompetence.
Commitment to candor: That which can be destroyed by the truth should be. You get full transparency from the company and the company expects full transparency from you. We never say anything about someone that we wouldn’t say to them directly. We give feedback with love and do not need to protect people from fleeting physical sensations.
A maniacal sense of urgency: We execute at an intensity that most people think is impossible. Speed is critical and we need things done yesterday. We all work very hard and in such a competitive world there really is no other way to win.
Enduring frugality: We are frugal. We hate being wasteful and we are anti-luxury. A culture of cheapness keeps us young. We spend our cash wisely & carefully — in a way that would make our grandmas proud.
Bulldozing barriers: The world is malleable and we shape it. We truly believe this and act accordingly. We are relentlessly resourceful and are at the mercy of no-one but ourselves. You’ll be shocked how capable you are and how much you can achieve.
Keep your head down: We’re boring people doing exciting work. We don’t chase short-term status — we ignore short-term dopamine hits and focus on what matters. Outsiders will underestimate us and we revel in that.
The power of focus: We live in a world of power laws and we cannot overestimate the unimportance of practically everything. Know your One Thing, and nail it.
🎯 “You just build a fing amazing experience. Make each step amazing. Make every decision in the long term interest of the customer. Give the customer massively more value than you take.”*

Compensation & Benefits

Compensation: $90-180k/year inc equity
Healthcare: comprehensive medical insurance (if appropriate)
Vacation: PTO with a yearly minimum (≥2wks/yr + local national holidays)
Remote: our team is fully distributed across the world and functions fully remotely
Personal development: budget for books, courses, coaching ($1200/yr)
Personal wellness: budget for gym, health apps ($1200/yr)
Coaching: free biweekly health coaching
Equipment: Macbook & work-from-home equipment provided as needed

About Buffer

At Buffer, we make social media and brand building software for small businesses, creators, and individuals. Our mission is to provide essential tools to help small businesses get off the ground and grow. Through exceptional customer service and uplifting content, we help our customers believe they can succeed and do good along the way.

We’re a fully distributed team, and we’ve always aimed to do things a little differently at Buffer. Since the early days, we’ve had a focus on building one of the most unique and fulfilling workplaces by rethinking a lot of traditional practices. We also default to transparency, so you can read all about our metrics, and our successes and failures along the way on our Transparency Dashboard.

We hire and work from all over the world. Please note that we do travel to work together in-person once or twice per year, and those events are highly encouraged to build deeper connections among our small team.

We're united by Buffer's values, and we celebrate our unique differences. We strive to create a diverse and inclusive work environment and are building a culture where underrepresented groups are welcome, and can flourish.

About the role

We're looking for a senior frontend engineer to join our newly formed Value-Led Growth team and help shape how we grow Buffer through genuine customer value. You'll take the lead on building core parts of our growth experience, including referral programs, conversion flows, free tools, and data-driven experimentation features.

We need someone with strong product instincts, growth domain experience, and the ability to work independently across team boundaries. You care about metrics and user behavior as much as polished UI — thoughtful conversion flows, data-driven decisions, and experiences that genuinely serve our users. You'll collaborate closely with our Staff Growth Product Manager, engineers from other teams, and various stakeholders to explore opportunities, validate ideas, and ship high-impact growth initiatives.

We're a small, collaborative team that puts value before revenue in our decision making. We iterate based on real user data, care deeply about long-term customer relationships, and focus on building trust through exceptional experiences. You'll have space to lead, evangelize growth thinking across Buffer, and help establish the foundations of our growth engineering culture.

What you’ll do

Lead the development of core growth features — referral systems, conversion flows, free tools, pricing experiments, and social viral loops that drive sustainable user acquisition and retention.
Drive growth experimentation — implement A/B tests, track key metrics, and build the infrastructure that enables rapid iteration and data-driven decision making across growth initiatives.
Collaborate across teams, you'll work closely with other teams to identify growth opportunities and implement solutions that span multiple domains.
Shape growth platform capabilities, build tools and systems that enable other teams to easily implement growth features, run experiments, and optimize their own conversion funnels.
Shape frontend architecture and UI standards, guide technical decisions from state management and component structure to evolving our internal design system (Popcorn), refining shared patterns, and ensuring our interfaces remain consistent, accessible, and scalable across growth initiatives.
Take shared ownership of product quality and system health. You'll participate in our on-call rotation — all engineers take a 24/7 week-long shift roughly once a quarter. You'll also contribute to the ongoing work that keeps our systems running smoothly and continuously improving, like fixing bugs, addressing security vulnerabilities, and other improvements
Contribute to shaping our team’s engineering culture by sharing knowledge, reviewing code, and helping us all get better over time.

Helpful skills and experience

You have solid experience building interactive, user-facing applications with modern web tech — we use React, TypeScript, and GraphQL, but we care more about your ability to reason well and learn quickly than a specific stack.
You understand growth domain challenges — maybe you've built referral systems, optimized conversion flows, or implemented experimentation frameworks — and you enjoy solving problems that directly impact business metrics.
You're comfortable with data and analytics — you can set up tracking, analyze experiment results, and make data-driven decisions about feature development and optimization.
You have strong product judgment and a good sense of taste. You notice the small things, care about the feel of an interface, and bring a high bar to the UI details that shape user experience.
You’re comfortable navigating ambiguity and working independently, can drive technical discussions across teams, and help establish engineering practices for a growing team.
You’ve led significant frontend initiatives or projects, bringing clarity and direction to complex problems and guiding work from early exploration through to delivery.
You have a personal stake in the world of content creation, maybe you’ve run a newsletter, built an audience on social media, or regularly share your own work online. You’ve used Buffer before and care about the experience of planning, creating, and publishing content.
You thrive in remote, async environments. You communicate clearly, support your teammates, and don’t wait for permission to make progress.
You’re product-minded and user-oriented — you think beyond the ticket, consider edge cases and user experience, and bring a strong sense of ownership to your work.
You’re comfortable working with backend code when needed, and you understand how frontend decisions connect to the bigger picture.
You’re fluent with AI tools and use them to work with more leverage and level up your own efficiency.
You’ve likely been doing this for 7+ years, but depth matters more to us than a specific number.

Our tech stack

We use React and TypeScript for our web frontends
We have internal design system called Popcorn that we started developing last year, it is built with Radix primitives, CSS modules, Storybook and our own system of design tokens
We are in the process of migrating to GraphQL, we use Apollo Client in our web application
We write automated tests with jest, react testing library (for integration tests) and Playwright (for e2e tests)
On the backend, we use NodeJS, TypeScript and MongoDB
We are running our services on AWS with Kubernetes. We follow a micro-services architecture and are currently moving our services into a central shared monorepo.

Interview process

Here's what our hiring process for this role is like.

Application. When submitting your application and resume, tell us why you want to join Buffer and take your time. This is your chance to make a strong first impression.

Please note: While we have several engineering roles open, we recommend applying to only one role - just choose one that resonates with you the most. If during our review or interviews we think you'd be great for a different position, we'll re-route your application internally.

Hiring manager interview. Chat with the hiring manager for your role to understand what it takes to work at Buffer. This is an opportunity for both sides to get to know each other and determine whether our expectations align.
Code review assignment. We'll send you 30-minute asynchronous assignment to review a pull request, to help us understand how you think about code and communicate technical ideas.

Additionally, for senior+ roles, we'll have an additional conversation about your leadership, how you work with teams, and how you approach the broader challenges that come with this level.
Meet the CEO. At the very end, you will have the opportunity to meet with Joel Gascoigne, our CEO. This is a great chance for you to gain a deeper understanding of Buffer's strategy, values, and work processes.
Collaboration period. This is experimental stage for us where you would work with us on a real project over 2 days (fully paid). The goal is to see how it feels to work in the team, both for us and for you. You'll meet a few bufferoos, we'll kickoff the project, and invite you to a Slack and you'll collaborate with the team on it.
Offer. We wrap it up with an offer and discuss the final details. We would align on the last bits before we make you part of the Buffer team 💛

At Buffer, we value diversity of experience, and we understand that comes in many forms. We’re dedicated to adding new perspectives to the team. So, if your experience is close to what we’re looking for, please consider applying.

By submitting the application, you consent to Buffer collecting and processing your personal data for recruiting purposes, find more details in our Privacy Policy.

Why Polar?

It's never been easier to build, ship and scale software.

But it's never been harder to monetize it.

We're obsessed over solving this to empower the future one-developer unicorns.

These unicorns will be rare but inevitable. Whether in 3, 5, or 10+ years, they also symbolize a broader shift already in motion and accelerating:

Smaller & smaller teams with...
Exponential revenue/employee growth
Focusing fully on their core product and marketing. Delegating & automating everything else that's boilerplate – be it in their codebase or business operations.

Exceptional billing primitives, APIs, SDKs and abstractions are a crucial foundation, but not enough. They will need a full-fledged platform to oversee, manage and scale their business.

Turning their software into an international business in 6 lines of code.

Join our small, talented and engineering-led team across Europe to shape how future software businesses are built. We focus on shipping at high velocity to serve developers in unlocking their next stage with their business. Everything else is secondary.

Role & responsibilities

We're hiring a Staff Frontend Engineer to help shape our architecture, standards, and user experience across both our dashboard and SDKs. You’ll lead the design and implementation of open source libraries that enable developers to integrate, customize, and deploy seamless billing flows - from checkout to post-purchase to customer portals.

You’ll also build end-to-end features in our dashboard that help developers manage their billing, customers, and businesses. This is a high-impact role with significant autonomy and ownership - your work will help define the future of billing for developers.

Shape the future of billing for developers - starting by designing APIs and SDKs that feel like magic, and working backwards through backend, infrastructure, operations, and even business needs to make it real
Build and ship delightful UIs and dashboard features using TypeScript, React, and Next.js
Design and maintain open source packages - components, hooks, and libraries that developers use to build custom billing experiences (think Shadcn for billing)
Define front-end standards and architecture across our codebase
Continuously improve performance, reliability, and developer experience across all surfaces

What we're looking for

10+ years of experience building high-quality front-end applications, libraries, and SDKs
Strong background of open source contributions and ideally some prominent packages of your own
Highly proficient in JavaScript/TypeScript and comfortable across multiple frameworks
Deep experience with React and Next.js
Passionate about developer experience and designing world-class SDKs/APIs
Constantly learning and trying out the latest and greatest frameworks, packages and tooling to refine your opinionated stance on best practices and stacks
Excellent problem-solving skills and a clear communicator
Proven track record in fast-paced, high-autonomy startup environments

How we hire

Our process is fully remote, and all communication happens via email, GitHub issues/PRs and/or video calls:

Application Review → Short intro call with Birk (Founder)

Assignment → Open source PR (Engineering) or case study

Review & interviews (2-3 video calls) to:

Infrastructure Engineering at Polar

We're thrilled to hire our first Infrastructure Engineer at Polar!

We want to avoid creating silos between product and infrastructure engineering. Or our infrastructure getting so complicated early on that backend engineers are unable to dive in and assist in case of issues (on-call).

However, we are looking for someone to obsess over how we can scale, reduce latency and maintain world-class uptime. Spearheading those efforts standalone, but in close collaboration with backend engineers across the team and designed to ensure the full team is familiar with our infrastructure and can contribute.

Our Stack

Frontend: React & Next.js with Tailwind CSS, Shadcn, TanStack Router and more.
Backend: Python (FastAPI), Postgres, Redis, Dramatiq,
Cloud: Vercel, Render & AWS

Always subject to change as we scale and new technologies emerge.

Role & responsibilities

We’re hiring a Staff Infrastructure Engineer to design, build, and operate the foundation that powers Polar. From payments orchestration to global payouts, our systems demand world-class availability, reliability, and trust. You’ll set the technical direction for our infrastructure and lead by doing; hands-on in code, but also raising the bar for the whole team.

Own the end-to-end architecture, implementation and maintenance of our infrastructure: design, deployment, scaling, observability, and security
Define standards and best practices for infrastructure across the engineering team
Lead reliability engineering practices: SLOs, on-call, incident response, and postmortems
Drive world-class observability: metrics, tracing, logging, and alerting
Build and evolve CI/CD pipelines and developer tooling to maximize velocity without compromising reliability
Continuously improve security, compliance, and data protection across production systems
Work with engineering team to design scalable, resilient systems for billing and financial operations
Mentor and level up backend engineers to contribute confidently to infrastructure and during on-call rotations

What we're looking for

8+ years of experience in infrastructure, SRE, or backend engineering roles
Comfortable as the first dedicated infra hire. Setting technical direction while executing hands-on
Proven track record designing and operating infrastructure for high-availability, high-security, mission-critical systems
Deep experience with cloud platforms (AWS, GCP, or similar) and infrastructure-as-code (Terraform, Pulumi, etc.)
Strong background in observability, reliability, and incident management
Collaborative by default. You design systems so others can contribute and maintain them, not just you
Excellent communicator and technical leader. Able to influence, mentor, and set standards across the team
