Fullstack Engineer (TypeScript), AI Engineering: Editor Extensions – Multi-Platform
An overview of this role
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 behavior 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. This role is a chance to combine fullstack engineering with cutting-edge AI-powered developer tooling in GitLab’s remote, asynchronous, and values-driven environment.
Some 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.
About the team
The Fullstack Engineer will be part of the Editor Extensions: Multi-Platform team, which focuses on bringing GitLab Duo directly into developers’ day-to-day workflows across multiple environments. We own key initiatives that deliver AI-assisted experiences in JetBrains IDEs, Visual Studio, and a new command-line interface, including shared UI systems and the GitLab Language Server. We operate fully remotely and collaborate asynchronously across multiple regions, leveraging GitLab's values of transparency and open communication. We face the challenge of building fast, intuitive, and consistent multi-platform developer experiences. We also continuously integrate emerging AI capabilities from the broader AI Engineering section. For more on how we work, you can explore GitLab’s public handbook and AI Engineering documentation.
