About PostHog

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

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.
PostHog 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, Workflow, revenue analytics, and support products. When we say every product, we really mean it!

We are:

Product-led. More than 100,000 companies have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.
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.
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.

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

What you'll be doing

As a Software Engineer on the Warehouse Pipeline team in the Data Stack group, you’ll build and iterate on our data import system.
Our import workers are built in python and we pull in data from APIs and databases in batches, process the data using Apache Arrow in memory, and move the data into object storage in open table formats.
You’ll build and maintain our source library, as we’re looking for creative ways to make our library manageable at scale. You’ll revamp our schema management strategy, and build resilient systems (e.g logging, observability, testing)

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