About The Position

The Visual Studio Engineering team builds the next-generation engineering system behind Visual Studio, the foundation that enables thousands of developers across DevDiv and Microsoft to build, test, and ship Visual Studio and related products with speed, reliability, and confidence. We are part of Core AI’s Developer Division, powering the tools and platforms that help developers innovate faster and ship with quality.
We are looking for a Principal Software Engineer who is passionate about building and evolving large-scale engineering systems, and who can drive technical strategy and execution across teams to solve complex challenges in Microsoft’s developer infrastructure. In this role, you will lead the technical direction for critical services and workflows that underpin Visual Studio’s build, test, and release ecosystem. You will partner closely with product and engineering leaders across DevDiv and 1ES to identify systemic friction, define long-term architectural direction, and deliver scalable, secure, and reliable solutions.
If you are excited about shaping developer productivity at Microsoft scale, building cloud platforms, applying AI to simplify engineering workflows, and raising the bar for how engineering systems are designed and operated, this is a unique opportunity to have broad impact. You will be a technical leader on a collaborative, data-driven team that values technical depth, clarity of design, and thoughtful execution. You will influence architecture across multiple services, mentor engineers, and help define how our engineering systems evolve to support Visual Studio and Microsoft for years to come.
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.
