Role overview

Join GitLab as a Senior Full Stack Engineer on the AI Engineering: Editor Extensions – Multi-Platform team. You’ll design and build tools that integrate GitLab Duo into developers’ day-to-day workflows across multiple platforms, providing technical leadership while championing quality and performance.

Key missions

• Design and build developer tools that integrate GitLab Duo into everyday developer workflows.
• Lead the design and implementation of multi-platform editor extensions that improve the developer experience.

Responsibilities

• Own large technical problems end-to-end, including architectural trade-offs.
• Provide technical leadership and mentor engineers through code reviews and guidance.
• Deliver high-quality, production-grade implementations with an emphasis on performance.

Requirements

• Understanding of Language Server Protocol (LSP) and practical experience with language servers and editor integrations.
• Experience building developer tooling (e.g., CLI tools and interactive terminal experiences).
• Ability to work effectively in a fully remote, largely asynchronous environment; clear English communication.
• Strong TypeScript proficiency across frontend and backend, including building and operating production Node.js services.

• Experience with IDE extension ecosystems (e.g., JetBrains): plugin architecture, lifecycle, and development workflows.

Additional notes

• GitLab encourages applications from candidates with varying experience levels; not all requirements must be met.
