As a Senior Software Engineer on the Duo CLI functional team, part of the Developer Clients group within Git Lab's AI Clients stage, you'll design and build tools that bring Git Lab Duo into developers' daily terminal workflows. You'll shape AI-assisted experiences across Git Lab Duo CLI and its supporting infrastructure, working mainly in Type Script across the frontend and backend and making key architectural decisions about the CLI's future direction.

You'll also have opportunities to contribute across Developer Clients, including our Jet Brains plugin in Kotlin and our VS Code extension in Type Script, when shared features, components, or cross-platform consistency call for it.

You'll provide technical leadership by breaking down complex problems, aligning on long-term direction, and maintaining a high bar for code quality, performance, and reliability. You'll collaborate closely with engineers across Developer Clients and the wider AI Clients stage, including the Duo Client SDK and Duo Chat groups, to make Git Lab Duo fast, intuitive, and deeply integrated wherever developers work.
