GitLab - Senior Fullstack Engineer (TypeScript), AI Engineering: Editor Extensions

• 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, lifecycle, and development workflows. • 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, making sound architectural trade-offs, and mentoring other engineers through code reviews and guidance. • Comfort working in a fully remote, largely asynchronous environment, with clear written and spoken English communication and alignment with GitLab's values and inclusive culture. • The Senior Fullstack Engineer role is part of GitLab's AI Engineering group on the Editor Extensions - Multi-Platform team, focused on building editor experiences that bring GitLab Duo into developers' daily workflows. The team designs and delivers multi-platform integrations across JetBrains IDEs, the terminal (GitLab Duo CLI), and shared components such as the GitLab Language Server and Vue-based UI systems, with an emphasis on consistent behavior, performance, and reliability. We're fully remote and collaborate asynchronously, partnering closely with product, design, and other engineering teams across AI Engineering to align on long-term architecture and ship iterative improvements. The challenges are both technical and product-driven: building responsive, trustworthy AI-assisted tooling, maintaining high-quality integrations across multiple platforms, and evolving shared foundations that keep pace with developer expectations and a fast-moving ecosystem. • How GitLab will support you • Benefits to support your health, finances, and well-being • Flexible Paid Time Off • Team Member Resource Groups • Equity Compensation & Employee Stock Purchase Plan • Growth and Development Fund • Please note that we welcome interest from candidates with varying levels of experience; many successful candidates do not meet every single requirement.
