An overview of this role

As a Staff Software Engineer, you'll help lead two important areas for GitLab Security: the data layer behind our vulnerability and dependency management capabilities, and our move toward services outside the GitLab monolith. You'll design and develop systems that ingest, store, index, and query security report data, including integrations with key third-party systems. With a strong focus on PostgreSQL and scalable backend design, your work will support security features delivered by teams across GitLab.

You'll take ownership of large deliverables from early ideas through implementation, working directly with product, design, frontend, and engineering partners to shape the technical and product roadmap. You'll stay hands-on across GitLab's Ruby on Rails application and newer services, including greenfield projects, while helping the team build its expertise in modular service design.

What you’ll do

- Lead large technical deliverables from initial problem definition through delivery, often across multiple months or quarters.

- Design and develop backend systems for vulnerability and dependency management, including security report ingestion, storage, indexing, querying, and integrations with key third-party systems.

- Build and improve systems using Ruby on Rails and PostgreSQL, and contribute to newer services using technologies such as Go or Rust where appropriate.

- Shape technical plans, break down complex work, and help other engineers deliver effectively.

- Work directly with product, design, frontend, and engineering partners to make clear decisions, resolve constraints, and deliver measurable progress.
