About PostHog

PostHog is an open-source product analytics platform. We provide product-led teams with everything they need to understand user behaviour, including funnels, session recording, user paths, multivariate testing, feature flags, heat maps, and more. PostHog can be deployed to the cloud, or self-hosted on existing infrastructure, removing the need to send data externally.

PostHog was created as an open source project during Y Combinator's W20 cohort and had the most successful B2B software launch on HackerNews since 2012 - with a product that was just 4 weeks old. Since then, more than 10,000 companies have installed the platform, we've had huge success with our paid upgrades, and we have raised $27m from some of the world's top investors, and have shown strong product-led growth - 97% driven by word of mouth.

Despite the tech market, we're default alive and doing better than ever! We've been averaging >20% monthly revenue growth, we are default alive, and we didn't raised a huge / now-overpriced round in 2021. While others are focused on layoffs and struggling to grow into huge valuations, we're focssing on an awesome product for end users, hiring (a handful of) exceptional team members and seeing fantastic increases in revenue as a result.

We’re now looking for a Senior Data Engineer to join our Ingestion team. We hire globally, but are currently restricted to GMT -5 to +2 time zones for this particular role.

What you’ll be doing

We are looking for someone to take our ingestion pipeline to the next level. You will be working with our super talented ingestion small team to iteratively build out and shore up the functionality of our ingestion pipeline. You'll be focused on the core of our data ingestion pipeline - our App service. It is responsible for transforming, augmenting, routing, and backfilling data to many different final destinations, including ClickHouse, the warehouse that we use to power PostHog.
