An overview of this role

We're looking for a Backend Engineer to join our Repository Management team within GitLab's Source Code stage. You'll help customers configure repositories with confidence so their GitLab projects support the way their teams work. As artificial intelligence agents increasingly write and manage code alongside people, you'll build guardrails that make development safe and trustworthy. You'll turn complex policy and repository management needs into reliable backend solutions that support people and the agents working on their behalf.

You'll work in one of GitLab's oldest and most complex product areas, using Ruby and GraphQL to improve a critical system that serves GitLab.com, self-managed instances, and GitLab Dedicated. Source Code provides the interface layer, through Gitaly, to the Git repositories that account for a large portion of GitLab traffic. With support from experienced team members, you'll help maintain high reliability through performance and structured query language tuning, caching, rate limiting, testing, observability, and resiliency. You'll collaborate with product management, product design, testing, security, user experience research, technical writing, Gitaly, Code Review, and Source Code Experience to deliver reliable and performant systems.
