Fullstack Engineer (TypeScript), AI Engineering: Duo Client SDK

Responsibilities

• Develop secure, well-tested, and performant TypeScript features that solve technical problems of moderate scope and complexity.
• Ship small features and improvements with minimal guidance, writing tests with every merge request and contributing to code reviews and design discussions.
• Extract and publish TypeScript packages from the GitLab Language Server, migrating consumers incrementally so no parallel implementation is left to drift.
• Design durable public APIs with clear interfaces, semantic versioning, changelogs, and deprecation paths for external consumers.
• Build isomorphic core packages that isolate platform-specific behavior in adapters at the edges.
• Build and improve SDK client surfaces, including Vue 3 components in Duo Chat on the web, in collaboration with product, design, and engineering teams.
• Strengthen credential handling across hosts, including bearer tokens, session cookies, and CSRF protection.
• Optimize bundle size, startup cost, and dependency weight for browser consumers, and support a Tier 2 on-call rotation for urgent engineering issues.
