As a Senior Backend Engineer (Ruby on Rails) on the Plan: Knowledge group, you'll help shape how teams plan, document, and share knowledge in GitLab. You'll build and improve the backend systems behind Wiki, Pages, Markdown, and text editors, while also helping design AI-powered capabilities such as the planner agent and Model Context Protocol (MCP) integrations that connect GitLab's GraphQL APIs with external tools. In this role, you'll work closely with frontend engineers, Product, UX, and Security to create reliable, scalable systems that support both technical and non-technical users across GitLab's planning experience. As part of GitLab's AI-first culture, you'll also use the Duo Agent Platform in your daily workflow to improve productivity and support faster iteration.
