About The Position

VS Code is where millions of developers turn ideas into working software. We are looking for a Principal Software Engineer to tackle hard product and platform challenges as VS Code and GitHub Copilot continue to reshape how developers build software. You will help to evolve VS Code as a market leading developer environment, seamlessly connecting its editor, agentic coding abilities, platform and extension ecosystem. You will identify where investment matters, prove difficult ideas in code, and establish approaches that multiple teams can build on. This is hands-on technical leadership: the opportunity to change both what developers can accomplish and what our engineering teams can deliver.

We work in the open, with direct feedback from developers and extension authors. You will partner with engineers, designers, researchers, and product leaders 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.

Microsoft’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. Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

• Experience providing technical leadership on AI-powered products, open-source projects, or extensible applications.

Responsibilities

• Identify significant product opportunities and systemic engineering problems; set technical direction that balances near-term delivery with long-term product and platform health.
• Prove approaches through prototypes, critical implementation, testing, and difficult debugging, using hands-on work to guide architectural decisions.
• Lead cross-team delivery across Microsoft and GitHub, resolving architectural disagreements, clarifying ownership and API boundaries, and enabling teams to deliver independently.
