Site Reliability Engineer

PostHog is the open source Product OS - it's a suite of product and data tools, built on the modern data stack. We provide product analytics, session recording, feature flags, a/b testing, event pipelines and a data warehouse. PostHog can be deployed to the cloud, or self-hosted on existing infrastructure, removing the need to send user data to a 3rd party.

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 raise a huge / now-overpriced round in 2021. Whilst others are focussed on layoffs and struggling to grow into huge valuations, we're focussing on an awesome product for end users, hiring (a handful of) exceptional team members and seeing fantastic increases in revenue as a result.

About the role

We even wrote a blog post about this one!

PostHog is looking for a creative and experienced Site Reliability Engineer to join our Infrastructure team, with members who drove infrastructure at Uber, Facebook, Twitter, and Slack.

We are actively investing in extending our deployment platform to make it easier to install and operate our stack wherever our customers need to run us. If you are interested in automating how we operate a data warehouse that runs anywhere and everywhere, this could be a great role for you

What we value

• We are open source - building a huge community around a free-for-life product is key to PostHog's strategy.

• We aim to become the most transparent company, ever. In order to enable teams to make great decisions, we share as much information as we can. In our public handbook everyone can read about our roadmap, how we pay (or even let go of) people, what our strategy is, and who we have raised money from. We also have regular team-wide feedback sessions, where we share honest feedback with each other.

• Working autonomously and maximizing impact - we don’t tell anyone what to do, everyone chooses what to work on next based on what is going to have the biggest impact on our customers.

• Solve big problems - we haven't built our defining feature yet. We are all about acting fast, innovating and iterating

Why we need you

• We are investing heavily in making PostHog the go-to data and product analytics application if you want to control the data yourself in your own cloud (AWS, GCP, Azure etc.). We have already invested several developer years in building a scalable Helm Chart but we need your help in scaling it even further.

• You will also be responsible - with the rest of the team of course - for scaling the components within the helm chart. Things like ClickHouse, Kafka, Zookeeper (for the time being since dependencies are slowly fading), Postgres, Redis, and PostHog services.

• Our goal is to make installing and operating our stack as seamless and straight forward as possible.

What you’ll bring

• You must have an interest in infrastructure, cloud platforms (GCP & AWS), large scale data systems, and Kubernetes!

• Experience in software development and operations, ideally in programming languages such as Golang, Java, Python, Bash, or Ruby.

• Experience working with containers and container runtimes such as Kubernetes or Mesos.

• You believe in infrastructure as code - you would love this role if you are excited about building large, dynamically scalable data intensive systems.

If this sounds like what you’d love to be doing, we can’t wait to hear from you. If you’re not sure that you exactly fit the above criteria, get in touch anyway. Alignment with our values is just as important as experience! 🙏
