About the role

Posthog is here to increase the number of successful products that exist in the world. Right now we are focusing on helping product creators understand how people are using their product. Where things go well. Where things don't go so well.

We have built a great service for understanding how users use products. Now we need to scale it and make sure it is rock solid. You will be joining a rapidly growing team helping us support the services that allow us to absorb billions of events without loss even during crazy peaks. You will also be helping out with keeping our query engine up during high loads. We also need to build out the infrastructure needed to deploy this stack on customer’s VPCs and equivalents so that they can maintain control over their data without any loss of quality of experience on Posthog.

Posthog is a well funded Y-Combinator and GV backed startup from the W20 batch and is growing rapidly. We love open source, data, and crafting beautiful products that are easy to use and provide clear value.

If you are interested in software infrastructure on Kubernetes, excited to work with an experienced software development team, this job is for you.

Here is what you will be working on:

  • Building AWS, GCP, Azure (and more!) deployment automation for delivering Posthog to ourselves and customers
  • Troubleshooting networking, compute, and Kubernetes failures.
  • Improving performance and robustness of cloud and customer deployments.
  • Hardening security all around.
  • Working on large scale OLAP databases with huge datasets (we use Clickhouse and love it)
  • Automate scaling Clickhouse for ourselves and our clients
  • Improving how we manage and scale Kafka

What you'll bring:

  • Strong experience in Linux systems administration, networks, performance troubleshooting.
  • Running and troubleshooting Kubernetes clusters, containerized networking and applications.
  • Intermediate knowledge of Golang, Rust, or Python.
  • Infrastructure and application security engineering experience is a plus.
  • Cloud infrastructure automation using Kubernetes
  • Clickhouse experience is a plus

What to expect once you apply:

  • We will send you a 30 minute SRE quiz
  • You will join a 30 minute intro call to walk you through culture, compensation, the interview process, and requirements.
  • Technical interview with the hiring team. This is usually 2 PostHog team members spending 45-60 minutes in conversation
  • PostHog SuperDay - this is a paid day of working with us, which we will fit around your schedule and have you work on something SRE related

Why you should join PostHog

We’re working to increase the number of successful products in the world

We’re a small (but growing) team building an open source platform that empowers customers to create successful products.

Until now, tools for building products have been fragmented. Product analytics, heat maps, session recording and A/B testing all provide immense value, but existing tools weren’t natively built to work together.

PostHog is different by offering these tools (and more) in a single platform that you can host yourself.

We started PostHog as part of 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.

We're proudly backed by some of the world's top investors and believe in product-led growth, where we build something awesome and let our product bring the users, rather than an outbound sales team and regular cold calls.

What does this mean for you? We have a lot of capital, but we're a lean, strong team - so you've got the opportunity to have a huge impact.
