Summary from the posting
ClickHouse is the core piece of infrastructure at PostHog. Every product and customer relies on it to ingest, store, and query data.
We need someone to automate, manage, and maintain ClickHouse as we grow towards capturing trillions of events per year and having one of the world’s largest clusters.
This includes ClickHouse operations and scaling infrastructure, as well as node and instance-level performance optimization. We want to ensure that we have the right hardware deployed at the right time for each workload on ClickHouse.
You'll build systems and automations for the provisioning and scaling of our large ClickHouse clusters, handling over 100 PB's of data.
This is a short summary. The full description, requirements and the application form are on PostHog's own career page.
