An overview of this role

The Create: Code Creation team builds and maintains GitLab's AI-powered code development tools that help developers write, review, and understand code more effectively. Our team has successfully launched multiple foundational AI capabilities including Code Suggestions (AI-assisted code completions in multiple IDEs), Duo Code Review (automated AI-powered code review), and the Knowledge Graph (intelligent code indexing and context system). We're now expanding and deepening these capabilities across GitLab Duo's AI suite.

As a Staff Engineer, you'll provide technical leadership for sophisticated systems that power our AI-driven code creation features. You'll architect solutions that analyze codebases to provide relevant context to large language models, design systems that coordinate multiple AI agents and tools, and help shape the technical direction of GitLab's AI initiatives. You'll work across multiple services and technologies including our main Rails application, AI Gateway (Python), Knowledge Graph (Rust), and Language Server (TypeScript), ensuring our solutions maintain high performance and reliability for our global user base.
