Principal Architect-UI Platforms

Architect, UI Platforms, Windows Platform & Developer (WPD) Organization. Would you like to help shape the UI platform that powers Windows experiences used by millions of developers and customers every day? The Windows Platform & Developer (WPD) Organization team builds and evolves the UI frameworks and APIs that first and thirdparty developers rely on to create highquality desktop and enterprise line-of-business (LOB) applications. We are looking for a UI Platform Architect to help guide the next phase of Windows UI Platform’s evolution (including WinUI3) —modernizing the platform, improving fundamentals such as performance and reliability, and ensuring the developer experience meets the expectations of today’s desktop and enterprise app builders. This role blends strategic thinking with handson technical leadership and offers the opportunity to influence a widely used platform while staying close to real developer scenarios. As a UI Platform Architect, you will also focus on evolving WinUI into a modern, AI‑native UI framework that remains competitive with SwiftUI while embracing a future where agents author a significant portion of application code. This requires rethinking WinUI as a declarative, composable, and semantically rich platform—one that is easy for web and SwiftUI developers to adopt, straightforward for AI agents to reason about, and powerful enough to enable dynamic, personalized user experiences at scale.
