In this role, you will own the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI, C#, XAML, and C++ as needed. You'll define best practices for Windows development across the codebase, covering code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability.
Key responsibilities include driving accessibility efforts by integrating Microsoft UI Automation and other Windows accessibility frameworks, ensuring keyboard navigation, screen-reader support, and usability for users with disabilities. You'll collaborate with product designers, UX researchers, and QA to shape feature planning and the long-term Windows platform roadmap. You'll take full ownership of feature lifecycles from conception through design, implementation, testing, release, and maintenance, ensuring quality and consistency. You'll also identify and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, and compatibility problems with robust architectural solutions.
Required qualifications include 3+ years of Windows desktop application development with Windows App SDK, WinUI, C#, and XAML, plus ideally native Windows code experience (C++, Win32/WinRT/COM). You need deep understanding of Windows application architecture and interop between managed and native code. You should have a proven track record shipping production-quality desktop applications emphasizing reliability, performance, scalability, and maintainability. Strong experience with Windows accessibility APIs and dedication to inclusive software is essential. You'll need excellent software engineering fundamentals (OOP, design patterns, data structures, algorithms, memory management, multi-threading), experience leading technical design and mentoring engineers, and strong communication skills.
Preferred qualifications include automated UI testing experience, performance optimization expertise, localization/globalization knowledge, familiarity with telemetry and crash reporting, CI/CD workflow experience, and demonstrated ability to own feature areas long-term.
