We are seeking a Principal Software Engineer to help redefine how engineering gets done across Windows Silicon and System Integration (WSSI) and demonstrate what agentic engineering can make possible for Windows at scale. The Windows Silicon and System Integration (WSSI) organization delivers a leading integrated silicon + OS platform for the new era of computing. Our work spans new and in-market devices, multiple form factors and silicon partners, and some of the hardest systems challenges in Windows, including performance, power, reliability, compatibility, and overall product quality. We believe agentic AI can fundamentally change how engineers build, validate, debug, and improve complex systems. As a Principal Software Engineer, you will set technical direction for agentic engineering across WSSI while remaining deeply engaged with the technology. You will identify the engineering problems where agents can have the greatest impact, architect and build solutions alongside teams, and take promising ideas from prototype to trusted production workflows. In this role, you will help turn WSSI's most successful agentic capabilities into a compelling technical story: demonstrating what is possible, sharing lessons and reusable approaches, building excitement and credibility with engineering leaders, and establishing WSSI as a source of innovation in agentic engineering across Windows + Devices and Microsoft. As those capabilities mature, you will identify opportunities to extend them to new engineering scenarios and partner organizations, creating new areas where WSSI technology and capabilities can have broader impact. This role therefore sits at the intersection of deep engineering, technical strategy, and organizational influence. You will bring together AI, engineering systems, telemetry, diagnostics, and developer workflows to create closed-loop experiences that help engineers find problems faster, understand root causes, develop solutions, and validate outcomes. At the same time, you will articulate the vision behind that work, engage technical leaders and partner teams, and create momentum around opportunities that can grow from successful WSSI solutions into broader engineering capabilities. This is not a role solely focused on introducing new AI tools. You will instead define how engineering itself evolves as agentic capabilities mature, while also shaping the role WSSI plays in that evolution. You will establish reusable technical patterns, raise the engineering bar for AI-enabled systems, influence teams across organizational boundaries, and build the mechanisms that allow successful approaches to scale while expanding the impact and reach of WSSI's agentic engineering capabilities. 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.
