Senior Fullstack Engineer (TypeScript), AI Engineering: Editor Extensions
An overview of this role
As a Senior Fullstack Engineer on the AI Engineering: Editor Extensions - Multi-Platform team at GitLab, you'll design and build tools that bring GitLab Duo into developers' daily workflows. You'll shape AI-assisted experiences across Duo CLI, JetBrains IDEs, the terminal, and other multi-platform interfaces. You'll work mainly in TypeScript across the frontend and backend, and you'll make key architectural decisions.
You'll also contribute to Kotlin-based JetBrains plugins and shared UI systems that power our next-generation editor experiences. As a senior engineer, you'll provide technical leadership by breaking down complex problems, aligning on long-term direction, and holding a high bar for code quality, performance, and reliability.
You'll collaborate closely with engineers across AI Engineering to ship features that make GitLab Duo feel fast, intuitive, and deeply integrated. Your work will span the GitLab Duo CLI, the GitLab Language Server, and shared Vue-based components that provide consistent, intelligent behavior across platforms.
What you’ll do
- Lead the design and implementation of multi-platform editor extensions that bring GitLab Duo into developers' daily workflows.
- Design, build, and operate TypeScript and Node.js services for the GitLab Duo CLI, including rich interactive terminal experiences.
- Develop and enhance our JetBrains IDE plugin in Kotlin using the IntelliJ Platform SDK.
- Implement and evolve features in our GitLab Language Server to deliver consistent AI-assisted workflows.
- Build modern, accessible UI components using Vue 3, shadcn-style component libraries, and Tailwind-based theming.
- Shape our multi-platform architecture, identify and reduce technical debt, and drive improvements to scalability.
- Collaborate with product, design, and engineers across AI Engineering to align technical decisions.
- Champion product quality, security, performance, and developer experience through high-quality reviews and mentorship.
What you’ll bring
- Strong proficiency with TypeScript across frontend and backend, including building and operating production Node.js services.
- Experience building developer tooling, such as command-line applications and rich interactive terminal experiences.
- Experience with IDE extension ecosystems (for example, JetBrains IDEs), including plugin architecture and lifecycle.
- Working knowledge of Kotlin (or modern Java) and interest in contributing to Kotlin-based JetBrains plugins using the IntelliJ Platform SDK.
- Understanding of the Language Server Protocol (LSP) and practical experience with language servers and editor integrations.
- A track record of owning large technical problems end to end and making sound architectural trade-offs.
- Comfort working in a fully remote, largely asynchronous environment, with clear written and spoken English communication.
