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.

A key focus is driving accessibility: integrating and validating Windows accessibility APIs (Microsoft UI Automation), ensuring proper keyboard navigation, screen-reader support, and usability for users with disabilities.
You'll collaborate with product designers, UX researchers, QA, and stakeholders 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. You'll identify and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, and compatibility problems, proposing robust architectural solutions.
Required qualifications: 3+ years of Windows desktop development with Windows App SDK, WinUI, C#, and XAML; deep understanding of Windows application architecture and interop between managed (.NET) 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); experience leading technical design, mentoring engineers, and conducting code reviews; strong communication and cross-functional collaboration skills; user-centric mindset.
Preferred: automated UI testing experience, performance optimization expertise, localization/globalization experience, familiarity with telemetry and crash reporting, CI/CD and release pipeline experience, demonstrated ability to own feature areas long-term.
