• Lead design and architecture of native Windows applications using Windows App SDK, WinUI, C#, XAML, and C++ as needed
• Define and enforce best practices for Windows desktop development: code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability
• Drive accessibility efforts by integrating and validating support for Windows accessibility APIs (Microsoft UI Automation), ensuring keyboard navigation, screen-reader support, and usability for users with disabilities
• Collaborate with product designers, UX researchers, QA, and stakeholders to shape feature planning and long-term Windows platform roadmap
• Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, and compatibility problems
• Mentor other engineers, conduct code reviews, and make architecture-level decisions
Required qualifications include 3+ years of Windows desktop application development with Windows App SDK/WinUI, C#, and XAML; deep understanding of Windows application architecture and interop between managed and native code; proven track record shipping production-quality desktop applications; strong experience with Windows accessibility APIs; excellent software engineering fundamentals (OOP, design patterns, data structures, algorithms, memory management, multi-threading); and demonstrated ability to lead technical design and mentor engineers.
Preferred experience includes automated UI testing, performance optimization for desktop apps, localization/globalization, telemetry and crash reporting, CI/CD workflows for desktop applications, and long-term ownership of feature areas.
