Software Engineer — Data Stack

ABOUT POSTHOG

We equip every developer to build successful products https://posthog.com/handbook/why-does-posthog-exist.

We started with open-source product analytics, launched out of Y Combinator's W20 cohort https://posthog.com/handbook/story.

We've since shipped more than a dozen products https://posthog.com/products, including a built-in data warehouse https://posthog.com/docs/data-warehouse, a customer data platform https://posthog.com/docs/cdp, and Max AI https://posthog.com/max, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.

Next on the roadmap are messaging, customer analytics, ai task creation and coding based on customer data, logs and support analytics.

Our values https://posthog.com/handbook/values are not a poster on the wall full of aspiration. They’ve come from how we really work, day in day out.

PostHog is open source https://posthog.com/docs/self-host product led, and a default alive https://paulgraham.com/aord.html company that is well funded.

WHAT YOU'LL BE DOING

As a Full Stack Software Engineer on the Data Stack team, you’ll build end user tools for understanding and traversing their data models.

You’ll work on materializing user defined queries, and schedule & resolve DAGs of query materialization.

You’ll debug stateful data workflows by digging into k8s pod metrics, and schedule jobs using Temporal.io http://Temporal.io. As you can see, there’s a huge breadth of challenges and opportunities to tackle, and nothing is off-limits.

The PostHog Data Stack is both a core product for our users and a foundational platform for our internal teams. Data is a first-class product at PostHog, not an afterthought.

You will have the chance to push the boundaries of what our Data Stack team can do while ensuring we remain stable and production-ready.

You now know what you’ll be doing, but what about what you’ll need to bring along?

YOU’LL FIT RIGHT IN IF:

- You’re a builder. You bring strong skills in building resilient systems, with experience in Kubernetes, Docker, and S3 at scale. We build in python. Async-python and Temporal.io http://Temporal.io skills are welcome.

- You have good practices around building resilient systems. Logging, testing and monitoring (observability), but you are also comfortable with debugging stateful, async data workflows by digging into k8s pod metrics.

- You are proficient in building UIs for data intensive tools. React is part of your toolset.

- You have experience designing and implementing reliable and highly available backend services. Having used Dbt is a plus.

- You bring a mix of skills. It’s not just about the query engine. You’ll need strong backend skills as we run a complex system.

- You love getting things done. Engineers at PostHog have an incredible amount of autonomy to decide what to work on, so you’ll need to be proactive and just git it done.

- You’re ready to do the best work of your career. We have incredible distribution, a big financial cushion and an amazing team. There’s probably no better place to see how far you can go.
