Modash gives brands the tools to work with the right content creators and helps creators earn a living doing what they love. Behind the scenes, we’re building the world-class data platform that powers creator discovery for thousands of companies — and we’re looking for a hardened Senior Data Engineer to shape the direction of the creator economy.

🚀 What your day-to-day will look like

We’re not a service function — data engineering is a core product capability at Modash, building products for customers to use. You’ll own projects end-to-end, from idea to launch.

Here’s a typical day:

• Start your day with a short standup
• Heads-down focus time to plan, build, iterate, and launch
• Minimal meetings — maximum ownership

You’ll be working on big, impactful projects like:

• Building a creator search engine indexing 200M+ influencer profiles
• Creating an understanding of the creators location, age, and interests at scale
• Creating systems to extract audience demographics from raw social data
• Shaping the future of AI-assisted search, exploring how LLMs and embeddings can enhance search and recommendations.

You won’t be patching pipelines — you’ll be creating data products from scratch that directly impact customers.

👥 The Data Team

At Modash, data engineering isn’t a support function — it’s at the heart of the product. You’ll be part of a growing team of 4 data engineers, working alongside 4 backend engineers as part of our broader data organization.

We work in two closely aligned teams:

• Data Engineering – responsible for building our data platform, pipelines, and data points (like for search).
• Backend Engineering – focused on APIs, infrastructure, and the product features that use our data.

We value autonomy, but we also love to work closely as a team — through pair programming, feedback, and shared wins. Everyone is expected to take ownership, but nobody works in isolation.

We’re remote-first, but we make time to connect IRL with regular team offsites, where we have fun, collaborate, and reflect.

⚙️ Our tech stack

• AWS with Pulumi (IaC)
• Spark (EMR) — mostly PySpark
• Airflow for orchestration
• DynamoDB, S3, Glue, Kinesis, Lambda, ECS
• GitHub, Confluence, Miro, Jira

🧪 The interview process

We move fast. You can get interviewed in under a week. Process consists of:

1. Intro chat

2. Technical interviews: 1. Coding challenge (in PySpark) and 2. System Design

3. Team fit / Project presentation

4. Culture & alignment call with the CEO Avery Shrader - That’s it!

• Hands-on experience with Python and SQL
• Comfortable working with unstructured data
• Experience with workflow orchestration tools like Airflow or AWS Step Functions
• Familiarity with the AWS ecosystem (Glue, EMR, DynamoDB, etc.)
• You've built full features from idea to production: planning & scoping → architecture → coding → release.
• You're based in Europe with at least a few hours overlap with GMT+3

✅ Bonus points if you…

• Have worked with AI/ML tools or LLMs
• Care deeply about code quality and system design.
• Are curious about the creator economy (we’ll help you get up to speed)

🧑‍🔧 We’re looking for people that

• Are tirelessly in search of the best versions of ourselves – Who want to really show what they’ve got and want to prove the world and themselves what they’re capable of.
• Are direct in their communication – We support and encourage one another through direct, immediate & helpful feedback.
• Know how to become autonomous - Who we can trust to do their best work without needing processes to guardrail.
• Are willing to take ownership to stand up for ourselves, our teams, and our communities.
• Have fun, are honest, and do great work – No title chasers, no finger pointers, no being awful. Absolutely no slowing down to protect ego.

Benefits

🎁 What we offer

• Fully remote — work from anywhere in Europe
• Unlimited paid vacation 🌴
• Flexible hours — async-friendly culture
• High ownership, low bureaucracy, no bullshit.
• Personal development support — courses, books, or conferences on us

About PostHog

We're shipping every product that companies need to run their business from their first day, to the day they IPO, and beyond. The operating system for folks who build software.

We started with open-source product analytics, launched out of Y Combinator's W20 cohort. We've since shipped more than a dozen products, including:

• A built-in data warehouse, so users can query product and customer data together using custom SQL insights.
• A customer data platform, so they can send their data wherever they need with ease.
• Max AI, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.

Next on the roadmap are CRM, messaging, revenue analytics, and support products. When we say every product that companies need to run their business, we really mean it!

We are:

1. Product-led. More than 100,000 companies have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.
2. Default alive. Revenue is growing 10% MoM on average, and we're very efficient. We raise money to push ambition and grow faster, not to keep the lights on.
3. Well-funded. We've raised more than $100m from some of the world's top investors. We're set up for a long, ambitious journey.

We're focused on building an awesome product for end users, hiring exceptional teammates, shipping fast, and being as weird as possible.

Things we care about

• Transparency: Everyone can read about our roadmap, how we pay (or even let go of) people, our strategy, and how we work, in our public company handbook. Internally, we share revenue, notes and slides from board meetings, and fundraising plans, so everyone has the context they need to make good decisions.
• Autonomy: We don’t tell anyone what to do. Everyone chooses what to work on next based on what's going to have the biggest impact on our customers, and what they find interesting and motivating to work on. Engineers lead product teams and make product decisions. Teams are flexible and easy to change when needed.
• Shipping fast: Why not now? We want to build a lot of products; we can't do that shipping at a normal pace. We've built the company around small teams – autonomous, highly-efficient groups of cracked engineers who can outship much larger companies because they own their products end-to-end.
• Time for building: Nothing gets shipped in a meeting. We're a natively remote company. We default to async communication – PRs > Issues > Slack. Tuesdays and Thursdays are meeting-free days, and we prioritize heads down building time over perfect coordination. This will be the most productive job you've ever had.
• Ambition: We want to solve big problems. We strongly believe that aiming for the best possible upside, and sometimes missing, is better than never trying. We're optimistic about what's possible and our ability to get there.
• Being weird: Weird means redesigning an already world-class website for the 5th time. It means shipping literally every product that relates to customer data. It means building an objectively unnecessary developer toy with dubious shareholder value. Doing weird stuff is a competitive advantage. And it's fun.

Who we're looking for

• Enthusiastic drivers. We need proactive people that can fully own projects and get them done, and know to get help when needed. This is what being a product engineer is all about. "Are we there yet?" is the wrong question.
• Optimistic problem solvers. Things get hard here sometimes – whether it's scaling, shipping complex products, handling a stream of support requests, or trying to ship something that touches multiple teams. We need people who won't get disheartened, and will collaborate, iterate, and ship their way out of anything.
• Grown ups. We’re an international bunch of weirdos, but one thing unites us: everyone is kind, considerate, and professional towards each other. This isn't about age or experience, it's about being low-ego, flexible, and respectful.
• Genuine builders. PostHog is full of people who just love building stuff, people who would still be building software even if there wasn't a paycheck at the end. If this sounds like you, we should talk.

What you'll be doing

• Owning products and features from beginning to end. This means originating ideas based on your intuition, talking to users, and understanding our strategy and goals. It means testing MVPs in production with real users. It means iterating on their feedback, owning pricing, and ensuring the ongoing success of your work.
• Collaborating with design (when necessary). Product engineers at PostHog are full stack, so we expect you to ship and own the basic UX of your work using our design system. From there, it's up to you to decide when to collaborate with our design team to iterate and polish the experience.
• Implementing AI features. LLMs, eh? They're getting prettaaay, prettaay good. All our products integrate with Max AI, so you'll likely be working with the Max AI team to implement AI features in your products.
• Talking to users. Good product engineers read feedback from users and iterate quickly. Great product engineers have users they're friendly with, talk with them frequently, bounce ideas off them, and iterate with them when they ship new things.
• Doing support. Every week, one person in each engineering team is designated the Support hero. Their job is to investigate and resolve issues reported by customers for their product. Giving users support from real engineers, and shipping fixes and improvements in real-time, is one of the best ways to spark joy in users. This role will also include some on-call time, too.
• Writing docs. We have a content team that will collaborate with you on reviewing, polishing, and improving your documentation, but the best person to document a new feature is the person who built it.

Requirements

• Full-stack experience with relevant technologies – e.g. Python or similar, React or similar, something to do with big data is a bonus.
• Experience taking a project from 0 to 1. You might have led a project, been a founder previously, or built an impressive side project.
• Strong writing skills. We document everything, most of it publicly. The ability to communicate your ideas and make persuasive arguments is essential.

Nice to have

• Have worked at a high-growth SaaS company before.
• Extensive knowledge of Django and/or TypeScript-based React.
• Experience building AI-native products, or integrating AI into existing software.

If you have a disability, please let us know if there's any way we can make the interview process better for you - we're happy to accommodate!

Help us build the multimodal data stack for physical AI

At Rerun, we’re building a new multimodal data stack for physical AI. Large parts of the physical-world economy will be transformed by these technologies, and we're building the data infrastructure and tools that enable it to happen. Data volumes grow big quickly with these applications and performance matters everywhere; from micro interactions to high throughput jobs.

With multimodal data stack we mean tools for extraction, ingestion, storage, querying, streaming, and visualization of temporal multimodal data. Rerun’s open source project is already loved by some of the best teams in the world, and focuses on visualizing and handling multimodal logs. You'll join a newly formed team building out Rerun's commercial offering for ingesting, indexing and querying multimodal data at scale.

What you'll work on

• You will work on a cloud-native analytical database system built for multimodal (often time-series) data.
  

• The system is built in Rust and makes extensive use of Apache Arrow. It supports specialised queries to handle robotics-style multimodal logs (very sparse and wide tables) and domain specific operators (e.g. related to 3D transforms).
  
  • Note: prior robotics knowledge is not necessary
• You will design, implement and operate the core pieces that make sure this data-intensive system is highly scalable, reliable and observable.

We'd love it if you have

• Experience with async Rust in production
• A deep understanding of all the systems, layers, and abstractions sitting between your code and the hardware, and willingness to move across them.
• Experience building highly scalable data-intensive systems
• Comfort with concepts like query planning, push-down filtering, and query optimisation
• Experience deploying and operating complex systems in the Cloud (AWS/GCP/Azure)
• Great communication skills in English - you'll be working in a tight-knit remote team
• A helpful attitude and a curious mind with an ownership mindset - we're all doing this together!

Nice-To-Haves

• Experience with Apache Arrow and Apache Datafusion
• Experience with GPU workloads
• Interest or experience in relevant domains like machine learning, robotics, AR/VR, or simulation

How we work at Rerun

• We're a remote company headquartered in Stockholm, Sweden.
• We meet up in person for a week roughly once a quarter
• The team you'll join has members in European and US-east timezones
• Everyone is available for synchronous work between 1:30–5:00pm CET.
• Given our current team distribution, candidates outside of Europe or the US will be considered on a case-by-case basis to ensure there’s enough overlap for effective collaboration.
• We've put together an uncommonly talented tech team, value agency and helpfulness highly, and expect everyone to take broad responsibility for what they build
• We offer competitive cash and equity compensation, six weeks paid vacation, and whatever hardware and software you need to do your job

Most of all we hope you're excited to build some really cool technology that will have a real impact on the world with us!

If you find that you don't fit neatly into this or any of the other open roles, we're not that rigid and are generally looking for great developers who can contribute to what we're building. Just go ahead and apply to the one you think is the closest and we'll take it from there!

What does AI Enabler Team do?

In the AI Enabler team, our day is usually full of R&D challenges. Have you ever encountered a situation where you need to expand your AI infrastructure so that the applications can automatically pick the right large language models (LLMs) that are both more cost-efficient and better performing? Most of us probably do nowadays, or at least understand the complexity of making such decisions while keeping track of our cloud budget.

One of the team's responsibilities is ensuring that whenever a customer makes AI-related decisions regarding their K8s infrastructure, they are implemented automatically without unnecessary costs or hassle. This is just one small piece of a bigger puzzle. To get into a more detailed perspective, ask yourself the following questions:

• How often do you use LLMs?
• What is the least expensive LLM you can pick for a given prompt without degrading the quality of the response?
• How much do your applications cost per 1 million tokens and how can you improve it?
• Which API keys have the biggest waste?
• How can you improve your frequently running prompt to use fewer tokens?
• What is fine-tuning and how to do it efficiently?
• What is a transformer?

These are just several of the many questions that are part of the daily work of this team.

Being a part of this team would involve design and decision-making end-to-end while collaborating with colleagues from other teams. Cast AI, being a technical product, encourages not only coding something as written in the JIRA ticket but also coming up with new features and potential solutions to customers' problems. Given that the team is working on a technical greenfield project, you will have the opportunity to impact it in many ways positively.

Responsibilities for the role:

• Evaluate and Analyze LLM performance
• Fine-Tune LLMs
• Optimize AI Models for Cost Efficiency
• Develop and implement data science solutions
• Architect and build inference and training pipelines, directly contributing through hands-on design, model training pipeline, and deployment strategies
• Stay up to date with industry trends.

Here are some of the tools we use daily:

• Python
• ClickHouse and PostgreSQL for persistence
• GCP Pub/Sub for messaging
• gRPC for internal communication
• REST for public APIs
• Kubernetes, which our product is evolving around
• AWS, GCP, and Azure cloud providers, which are currently supported in our platform
• We use GitLab CI with ArgoCD as our GitOps CD engine
• Prometheus, Grafana, Loki, and Tempo for observability.

Requirements

• Experience with designing a production-grade machine learning system
• Strong software engineering skills in Python
• Ability to move fast in an environment where things are sometimes loosely defined and may have competing priorities or deadlines
• Experience with the design and implementation of efficient model training and inference pipelines end to end
• 5+ years of hands-on experience in Data Science and Machine Learning, with a proven track record, demonstrated through a robust portfolio of projects
• You have to be physically in any of the European countries GMT 0 to GMT +3
• Strong English skills
• Strong verbal and written communication skills
• Ability to work independently and collaborate in a group.

What's in it for you?

• Competitive salary (€6,500 - €9,000 gross, depending on the level of experience) with equity options
• Direct impact on the product in a cutting-edge company that’s reshaping cloud automation and optimization
• Collaborate with a global team of top cloud experts and innovators passionate about pushing the boundaries of Kubernetes technology
• Fast development cycles with a short feedback loop and direct customer impact
• Transparent work environment
• Focused work with minimal meetings and bureaucracy
• 10% of your time dedicated to self-improvement and personal projects.

Sr. Data Scientist

Job Posted: July 21, 2025

Location: Americas (North, Central and South America), EMEA (Europe, the Middle East and Africa)

Zapier is hiring Senior Data Scientists to join our growing Data team and support two high-impact areas of the business: Enterprise (Upmarket), and Ecosystem. While each domain has its own focus, all roles share a common goal — to design and deliver data products and insights that accelerate decision-making, power intelligent features, and enable both internal teams and customers to move faster with confidence.

As a Senior Data Scientist at Zapier, you won’t just analyze data, you’ll help build the systems and tools that turn insight into action. From designing lead scoring models and partner intelligence systems to tracking integration performance or delivering customer-facing usage analytics, your work will shape how we understand our users, optimize our operations, and scale our go-to-market strategies.

You’ll collaborate closely with cross-functional stakeholders in Product, Sales, Marketing, Success, and Finance, partnering with Data Warehouse Engineers to create scalable, reusable pipelines and analytical frameworks. In some cases, your work will feed into the product itself, helping Zapier users make smarter decisions, automate faster, and get more value from the platform.

Whether you're guiding how Zapier scales its enterprise motion, enriching our app ecosystem, or informing financial and GTM strategies, you’ll play a critical role in translating data into durable business leverage.

This is a high-impact opportunity for someone who blends technical excellence, product thinking, and a passion for building AI-informed, insight-driven systems that create lasting value at scale.

Our philosophy for hiring

• Our Commitment to Applicants

About You

• You’re technically fluent and hands-on. You bring senior-level experience—typically 5+ years—in data science or a related analytical role. You write production-grade Python (or R), write high-quality SQL, and design robust experiments and ML models that drive real-world impact. You’ve built systems that are as scalable as they are insightful.
• You think like a product builder. You design data products and models that don’t just explain what happened—they change what happens next. You thrive in ownership-heavy environments and approach problems like a PM: proactively ideating, prioritizing for impact, designing with users in mind, and iterating quickly.
• You’re fluent in AI and automation. You’re actively using modern AI tools (e.g. LLMs, AutoML, orchestration frameworks) to accelerate your workflows and solve new types of problems. You’re not just curious—you’re hands-on.
• You care deeply about quality and clarity. You hold a high bar for data instrumentation, statistical rigor, and communication. You simplify complexity, document thoroughly, and collaborate across technical and non-technical partners in a remote-first environment.
• You build for scale and enablement. You help teams define and own their KPIs, build self-serve dashboards, and use data to make better decisions faster. You create systems and documentation that make insight accessible—not just available.
• You value collaboration and knowledge sharing. You work effectively with teammates at all technical levels. You take ownership of filling knowledge gaps about the data products you manage and contribute to comprehensive documentation to elevate your peers with what you’ve learned.

Things You’ll Do

• Build and deploy data products that serve both internal and external customers
• Develop scalable frameworks for efficiently deploying models and deriving actionable insights.
• Analyze user behavior to identify and explain key drivers of outcomes such as activation, engagement, upgrades, and churn.
• Collaborate with business teams to design, analyze, and interpret experiments aimed at improving key metrics.
• Conduct proactive research into high-potential areas, including defining data-driven customer segments and success signals to dynamically shape the product experience; identifying business risks and opportunities through attribution data; understanding which customers benefit most from Upmarket offerings; and figuring out how to boost Upmarket’s contribution to revenue generation.
• Ensure all teams data-driven insights and can answer their own first-order questions. Develop data literacy programs and provide easy-to-use tools with clear documentation, examples, and tutorials.
• Perform basic ETL tasks to model new dimensions and facts in our data warehouse’s dimensional model. For the heavier lifts, you’ll be supported by Data Warehouse Engineering colleagues.
• Work with tools such as SQL, Looker, dbt, Databricks, Airflow, Eppo, and Python or R.

Modash gives brands the tools to work with the right content creators and helps creators earn a living doing what they love. Behind the scenes, we’re building the world-class data platform that powers creator discovery for thousands of companies — and we’re looking for a hardened Senior Backend Engineer to shape the direction of the creator economy.

🚀 What your day-to-day will look like

We’re not a service function — Data & Backend Engineering are core product capabilities at Modash, building products for customers to use. You’ll own projects end-to-end, from idea to launch.

Here’s a typical day:

• Start your day with a short standup
• Heads-down focus time to plan, build, iterate, and launch
• Minimal meetings — maximum ownership

You’ll be working on big, impactful projects like:

• Building a creator search engine indexing 350M+ influencer profiles
• Creating an understanding of the creators location, age, and interests at scale
• Creating systems to extract audience demographics from raw social data
• Shaping the future of AI-assisted search, exploring how LLMs and embeddings can enhance search and recommendations.

You won’t be patching pipelines — you’ll be creating data products from scratch that directly impact customers.

👥 The Data Team

At Modash, data engineering isn’t a support function — it’s at the heart of the product. You’ll be part of a growing team of 4 data engineers, working alongside 4 backend engineers as part of our broader data organization.

We work in two closely aligned teams:

• Data Engineering – responsible for building our data platform, pipelines, and data points (like for search).
• Backend Engineering – focused on APIs, infrastructure, and the product features that use our data.

We value autonomy, but we also love to work closely as a team — through pair programming, feedback, and shared wins. Everyone is expected to take ownership, but nobody works in isolation.

We’re remote-first, but we make time to connect IRL with regular team offsites, where we have fun, collaborate, and reflect.

⚙️ Our tech stack

• AWS with Pulumi (IaC)
• Typescript and Node.js
• ElasticSearch
• Airflow for orchestration
• Spark (EMR) — mostly PySpark
• SageMaker, DynamoDB, S3, Glue, Kinesis, Lambda, ECS
• GitHub, Confluence, Miro, Jira

🧪 The interview process

We move fast. You can get interviewed in under a week. Process consists of:

1. Intro chat

2. Technical interviews: 1. Coding challenge (Typescript) and 2. System Design

3. Culture & alignment call with the CEO Avery Shrader - That’s it!

Requirements

🛠 Skillset we’re looking for

• Solid experience as a Backend Engineer handling large-scale APIs
• Strong experience with TypeScript and NodeJS
• Deep expertise with Elasticsearch or comparable search technologies
• Hands-on experience with scraping, collecting, and/or processing data.
• Familiarity with the AWS ecosystem (Glue, EMR, DynamoDB, etc.)
• You've built full features from idea to production: planning & scoping → architecture → coding → release.
• Experience in a fast-paced startup with strong ownership
• You're based in Europe with at least a few hours overlap with GMT+3

✅ Bonus points if you…

• Have worked with AI/ML tools or LLMs
• Care deeply about code quality and system design.
• Are curious about the creator economy (we’ll help you get up to speed)

🧑‍🔧 We’re looking for people that

• Are tirelessly in search of the best versions of ourselves – Who want to really show what they’ve got and want to prove the world and themselves what they’re capable of.
• Are direct in their communication – We support and encourage one another through direct, immediate & helpful feedback.
• Know how to become autonomous - Who we can trust to do their best work without needing processes to guardrail.
• Are willing to take ownership to stand up for ourselves, our teams, and our communities.
• Have fun, are honest, and do great work – No title chasers, no finger pointers, no being awful. Absolutely no slowing down to protect ego.

Benefits

🎁 What we offer

• Fully remote — work from anywhere in Europe
• Unlimited paid vacation 🌴
• Flexible hours — async-friendly culture
• High ownership, low bureaucracy, no bullshit.
• Personal development support — courses, books, or conferences on us
• Regular offsites — connect with your team IRL

🔍 What We’re Looking For

We're looking for a software engineer who thrives at the intersection of data, software and infrastructure. You've worked in data-intensive environments and enjoy designing clean systems that move and transform data at scale. You’re someone who approaches data engineering as a software discipline — building reliable, tested, maintainable systems that empower others.

You'll work on building internal tools, pipelines, and APIs that support analytics, product features, and machine learning applications. You'll collaborate closely with both product and engineering teams to make our data infrastructure seamless, efficient, and delightful to use.

Stack

• Cloud: AWS
• Data Stores: Relational and non-relational e.g. CockroachDB, DynamoDB, Elasticsearch
• Data Warehouse: Snowflake
• Processing: Batch & streaming including CDC pipelines
• Languages: Python
• Infrastructure: Kubernetes + Helm, Terraform (IaC)
• Orchestration & Transformations: dbt
• Observability: OpenTelemetry, Datadog
• Dev Practices: CI/CD, automated testing, containerisation

Core Skills

• Strong software engineering fundamentals: testing, code reviews, clean abstractions
• Proficient in Python and SQL
• Comfortable working across infrastructure and data systems
• Experience building and maintaining batch and/or streaming data pipelines
• Familiarity with modern data warehouses (e.g., Snowflake) and transformation tools like dbt
• Comfortable navigating cloud-native ecosystems (AWS, K8s, Terraform)

Mindset & Collaboration

• Clear and thoughtful communicator (written and verbal)
• Detail-oriented
• Team player (“our code,” not “my code”)
• Eager to learn and share
• Adaptable — comfortable with ambiguity and shifting priorities

🚫 You may not like it here if:

• You enjoy working in an office-setting, we are remote-first and always will be!
• You are not comfortable with shifting context and navigating ambiguity
• You don’t enjoy testing your code, we have no testers or QA’s here at Primer

✅ Our interview process

• 30 minute call with a Talent Partner
• 45 min Hiring Manager interview
• Take home task followed by a 60 minute interview
• 60 minute final stage interview

Unfortunately we are unable to offer sponsorships or relocation packages at this time.

What’s the culture like at Primer?

We’re building a culture where people can come and do their best work and enjoy it. We want our people to be proud of the impact that they have at Primer, and of the work that they are doing. You will be working with a team of people who are mission-driven, smart, and reflective, and who are invested in building exceptional products and delivering success for our merchants (and we also know how to have fun along the way).

We work remotely. We believe that building a successful, profitable company goes beyond proximity. We invest in our relationships with each other through great remote working practices and thoughtfully designed face-to-face time together. Our heads-together time comes in the form of workations, our annual company retreat, and co-working space access worldwide.

Finally, let’s go ahead and say it. The work that we do is challenging. Startups are a challenge, building category defining products is a challenge. You should be prepared for a challenge at Primer. But, there’s a big difference between a challenge and a struggle. The key difference is that the right challenge comes with the right support structures, an acceptance that not everything always goes to plan, a collaborative environment, and a great team around you. It’s never a challenge that you will face alone.

Our benefits:

• We are fully remote
• Competitive share options
• Uncapped holiday, with 25 days minimum to be taken
• Co-working space access
• Workations & company retreat
• The best equipment for your role
• £500 towards your home office setup
• Generous learning budget
• Medical insurance
• A broad set of additional perks and benefits (depending on location)
