• Define and enforce best practices for Windows development: code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability

• Collaborate with product designers, UX researchers, QA, and stakeholders to shape feature planning and long-term 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 using 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; and demonstrated ability to lead technical design and mentor engineers.
Preferred experience includes automated UI testing, performance optimization for desktop apps, localization/internationalization, telemetry and crash reporting, CI/CD workflows for desktop applications, and long-term ownership of feature areas.
