About this job
About the role We're looking for a Backend Engineer to join our Repository Services team in GitLab's Create stage. The team owns the repository side of Source Code: how code gets into a repository, who may change it, and how those changes are verified. We build this as an access layer on the primitives the Gitaly team provides, for GitLab's own features and for the artificial intelligence agents now writing and pushing code alongside people. You'll work in one of GitLab's oldest and most complex product areas, using Ruby and GraphQL across GitLab.com, self-managed instances, and GitLab Dedicated. Repository Services is a new team, and its first months are about reliability and support, so you'll spend real time on performance and structured query language tuning, caching, rate limiting,…
This is a short summary.
