Backend Engineer, Source Code: Repository Services (Ruby)

Overview

Backend Engineer on the Repository Services team in GitLab's Create stage, owning the repository side of Source Code: how code gets into a repository, who may change it, and how those changes are verified.

What you'll do

• Develop secure, well-tested, performant features and improvements using Ruby and GraphQL.
• Work through complex requirements and legacy constraints to deliver clear solutions while protecting the reliability of this critical system.
• Design and maintain backend services, application programming interfaces, data models, and business logic that control how code reaches a repository, who may change it, and how it is verified.
• Build on the primitives Gitaly provides and work closely with the Gitaly team.
• Triage and fix bugs and support requests for the features the team owns.
• Collaborate across functions and teams, both asynchronously and synchronously, and involve domain experts when their input will improve the outcome.
• Use artificial intelligence agents for well-scoped work when they can speed up delivery without sacrificing quality, and critically review their output.
• Write maintainable code that follows GitLab's standards and contribute to constructive code reviews.
• Help strengthen reliability by monitoring production health metrics, participating in Tier 2 on-call, troubleshooting incidents, contributing to root cause analysis, and improving observability and resiliency.
• Share knowledge through code review, technical documentation, and everyday collaboration while learning from others.

What you'll need

• Professional experience building backend web applications, services, or application programming interfaces, with experience using Ruby and GraphQL.
• An understanding of relational databases, structured query language, data modeling, caching, background processing, and backend performance practices.
• Experience contributing to user-facing workflows and maintaining their underlying systems.
• Experience writing backend unit and integration tests, with familiarity with the testing pyramid, Git, and collaborative code review processes.
• Experience using artificial intelligence coding agents and reviewing their output, or an interest in building these skills in a complex monorepo.
