PostHog started as open-source product analytics out of Y Combinator's W20 cohort and has become the co-pilot platform for product development — including PostHog Code, a built-in data warehouse and AI-powered analysis. The team is fully remote, transparent and ships fast.

The mission

ClickHouse is the backbone of PostHog. Every product and every customer depends on it to ingest, store and query data. As PostHog grows toward trillions of captured events per year, it needs an engineer to automate, manage and maintain ClickHouse across one of the world's largest clusters.

What you will be doing

Operating and scaling ClickHouse infrastructure, including node and instance-level performance tuning
Building automation for provisioning and scaling clusters that hold over 100 PB of data
Using Terraform, Ansible and Kubernetes to drive dynamic instance provisioning
Experimenting with bleeding-edge ClickHouse features, including open-format backed tables
Testing the latest cloud hardware — with a real budget to find the optimal setup

What you need

Hands-on experience operating ClickHouse or similar columnar databases at serious scale
Strong infrastructure engineering skills and automation instincts
A performance-first mindset: latency, throughput and cost matter
Comfort working autonomously in a remote, async-first team

Why this role stands out

Few engineers get to manage infrastructure of this scale with this much autonomy. Transparent salaries, no unnecessary process, and colleagues who genuinely care about craft.
