Steer the creation of native Windows desktop applications by guiding architecture and implementation with Windows App SDK, WinUI (or related UI frameworks), using C# and XAML, with C++ involvement as needed.
Set and uphold best practices for Windows desktop development across the codebase, covering architecture, performance, memory efficiency, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability.
Lead accessibility initiatives by integrating and validating support for Windows accessibility APIs such as Microsoft UI Automation; ensure controls, focus management, keyboard navigation, screen reader compatibility, and inclusive usability.
Collaborate with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and the Windows platform roadmap.
Own end-to-end feature lifecycles from concept through design, implementation, testing, release, and ongoing maintenance, ensuring quality and consistency across releases.
Identify and resolve complex bugs, performance bottlenecks, memory leaks, rendering or compatibility issues, and propose robust architectural or design improvements.

Minimum three years of Windows desktop development experience using Windows App SDK and WinUI (or similar), with C# and XAML; ideally additional experience with native Windows code (C++, Win32/WinRT/COM).
Strong understanding of Windows app architecture, including interop between managed (.NET) and native code.
Proven track record delivering production-grade desktop applications with emphasis on reliability, performance, scalability, and maintainability.
Extensive experience with Windows accessibility APIs such as Microsoft UI Automation, and a commitment to accessible software.
Solid software engineering fundamentals including OOP, design patterns, data structures, algorithms, memory management, and multi-threading or asynchronous programming as appropriate.
Experience guiding technical design, mentoring engineers, conducting code reviews, and making architecture level decisions.
Excellent communication skills to articulate tradeoffs, collaborate across teams, and drive consensus.
User-centric mindset focused on delivering polished, intuitive, and accessible experiences for end users.

Significant impact on the Windows product architecture and user experience that reaches millions of users.
Collaborative, flat engineering culture that values hands-on building and technical decision making.
Opportunities to lead, mentor others, and influence technical direction with potential growth into roles such as Tech Lead or Architect.
Flexibility, autonomy, and responsibility to define how to solve problems, own features end to end, and contribute to long term product vision.
A purpose driven mission focused on reliability, accessibility, and user centered software that makes a real difference.
