Summary from the posting
ClickHouse is looking for a Principal Database Performance Engineer to join the team behind our high-performance analytics database service.
In this role, you will drive performance and scalability improvements across the stack, taking on ambiguous, high-impact technical challenges most engineers never get to touch.
Our performance team owns the core of query execution - filters, aggregation, joins, and the index structures that make them fast.
We're looking for a sharp, passionate engineer who wants to own database performance end-to-end on a petabyte-scale cloud database, from initial analysis and implementation, through production rollout.
This is a short summary. The full description, requirements and the application form are on ClickHouse's own career page.
