Job summary

GitLab is seeking a Senior Software Engineer for the Duo CLI team, working primarily in TypeScript to design and implement CLI features and IDE extensions. You will own end-to-end delivery, improve reliability, and collaborate across Developer Clients and the AI Clients stage in a fully remote, asynchronous setup.

Join a high-performance culture with emphasis on security, quality, and developer experience. Poland-based base salary is supported with EU-resident transparency.

Qualifications

• Strong proficiency in TypeScript and an interest in developer tooling and command-line interface design.
• Experience building or maintaining command-line tools or other developer-facing tooling, including command and flag design, terminal user interfaces, output formatting, scripting-friendly behavior, and backward compatibility.
• Experience owning technical problems end to end, making sound architectural trade-offs, and guiding other engineers through code reviews.
• Clear written and spoken English communication skills and comfort working in a fully remote, largely asynchronous environment.
• Alignment with GitLab's values and commitment to an inclusive culture.
• Experience with IDE extension development, such as JetBrains plugins in Kotlin or VS Code extensions, and understanding of the Language Server Protocol (LSP) is helpful but not required.

Responsibilities

• Own the design, development, and evolution of GitLab Duo CLI features from problem definition with Product through implementation, rollout, and iteration, measuring success through feature usage and feedback.
• Build interactive terminal experiences in TypeScript, with careful command and flag design, clear output formatting, scripting-friendly behavior, and backward compatibility.
• Drive reliability, observability, and performance improvements for the CLI, measuring progress through reliability and performance metrics while reducing technical debt as the product and its usage grow.
• Collaborate with Product, Design, and engineers across Developer Clients and the wider AI Clients stage to align technical decisions with GitLab's broader strategy.
• Champion product quality, security, and developer experience through thoughtful reviews and mentorship.
• Contribute to IDE extension work across the group when useful, including the JetBrains plugin in Kotlin and the VS Code extension in TypeScript.
