Our mission is to enable everyone to contribute to and co‐create the software that powers our world. When everyone can contribute, consumers become contributors, significantly accelerating human progress. Our platform unites teams and organizations, breaking down barriers and redefining what's possible in software development.
As a Fullstack Engineer on the AI Engineering: Editor Extensions Multi‐Platform team at GitLab, you'll build tools that bring GitLab Duo directly into developers' daily workflows. You'll help shape AI‐assisted experiences in the places developers spend most of their time, including JetBrains IDEs, the terminal, and future multi‐platform interfaces. In this role, you'll work primarily with TypeScript across frontend and backend. You'll also contribute to Kotlin‐based JetBrains plugins and shared UI systems that power our next‐generation editor experiences.
You will collaborate closely with other engineers in the AI Engineering section to design, implement, and evolve features that make GitLab Duo feel fast, intuitive, and deeply integrated. Your work will span the Duo CLI, the GitLab Language Server, and shared Vue‐based components that provide consistent, intelligent behaviour across platforms. You will have the opportunity to influence architecture, improve performance at scale, and shape internal standards for high‐quality, maintainable TypeScript and Kotlin code.
Examples of Our Projects:
- GitLab Duo plugin for JetBrains IDEs
- GitLab Language Server
What You'll Do:
- Contribute across the stack to build and refine multi‐platform editor extensions that bring GitLab Duo directly into developers' daily workflows.
- Design, implement, and maintain TypeScript and Node.js services that power our GitLab Duo CLI, including rich interactive terminal experiences.
- Develop and enhance our JetBrains IDE plugin, working with the IntelliJ Platform SDK and Kotlin to deliver performant, intuitive in‐IDE experiences.
- Implement features and improvements in our GitLab Language Server to provide consistent, AI‐assisted workflows across editors and platforms.
- Build modern, accessible UI components using Vue 3, shadcn‐style component libraries, and Tailwind‐based theming as part of our next‐generation editor experience.
- Collaborate closely with product, design, and other engineering teams in the AI Engineering section to align technical decisions with our broader multi‐platform strategy.
- Advocate for and contribute to improvements in product quality, security, performance, and developer experience, including refining internal engineering standards and best practices.
- Participate in code reviews, provide mentorship to peers, and help shape the technical direction of editor extensions and multi‐platform developer tooling at GitLab.
What You'll Bring:
- Strong proficiency with TypeScript across frontend and backend, including building and maintaining Node.js‐based services.
- Hands‐on experience building command‐line applications and interactive terminal experiences using modern frameworks or libraries.
- Experience working with modern IDE extension ecosystems (for example, JetBrains IDEs or similar platforms), including understanding of plugin architectures and development workflows.
- Experience with Kotlin or modern Java, and an interest in applying or extending that experience to multi‐platform development.
- Understanding of the Language Server Protocol (LSP) or experience working with language servers and editor integration.
- Experience with modern build systems, including managing multi‐module builds and dependencies.
- Experience with Vue 3, the Composition API, and reactive UI design, including work with component libraries and theming systems.
