We are looking for a Senior Software Engineer to help build its next generation of editing, development, and GitHub Copilot experiences. You will help to make complex developer workflows feel simple, from everyday coding and debugging to delegating work to AI. This is hands-on product engineering in a large TypeScript and Rust codebase: you will shape a feature or technical area's direction, implement it, and keep improving it after release. We value engineers who care about how software feels, make sound decisions amid ambiguity, and learn from what they ship.\nAbout the team\nWe work in the open, with direct feedback from developers and extension authors. You will collaborate with engineers, designers, researchers, and product teams across our team, GitHub, and Microsoft. We combine community feedback, research, experiments, and engineering judgment to decide what to build. Performance, accessibility, extensibility, security, and developer control are part of the product, not finishing touches.\nExamples of work\nThe role spans core VS Code and Copilot; illustrative projects include:\nImprove navigation and editing in large repositories without slowing down startup or typing.\nBuild a Copilot workflow that helps developers delegate a coding task, inspect the changes, and validate them using VS Code's review, testing, and debugging tools.\nExtend VS Code APIs so new capabilities work reliably with existing extensions and remote development environments.\nRefine our existing engineering process with custom tools fine-tuned for throughput and quality.\nMicrosoft’s mission is to empower every person and every organization on the planet to achieve more. As part of GitHub and CoreAI, we build developer tools that materially improve how software is written, reviewed, and shipped, while maintaining a culture of ownership, rigor, and technical excellence.\nMicrosoft’s mission is to empower every person and every organization on the planet to achieve more.
