An overview of this role
As a Senior Backend Engineer with the Database Excellence group, you'll build and evolve the data frameworks and tooling that keep GitLab's application datastores scalable, healthy, and safe across both GitLab.com and thousands of self-managed instances. A primary focus for this role is building proactive data growth controls for GitLab.com, including retention and lifecycle management frameworks, enforcement of retention policies at schema-change time, and tooling that keeps database growth sustainable as AI-driven development accelerates how quickly data accumulates. You'll help teams across GitLab reason confidently about data architecture, placement, and lifecycle management, while proactively identifying saturation points in our GitLab.com infrastructure and driving corrective actions with partner teams. With the team's recent move into the Data Engineering organization, you'll also shape new scalability and data health features for self-managed customers, working hands-on with PostgreSQL and Ruby on Rails in a fully remote, highly collaborative environment.
Some examples of our projects:
- Data Growth Controls (retention enforcement and data lifecycle management)
- SQL Traffic Replay Tooling
- Background Operations Framework
What you'll do
- Develop and iterate backend features and data frameworks that make it safe and efficient for GitLab teams to work with data at scale across SaaS and self-managed deployments.
