Responsibilities

• Lead the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI, C#, XAML, and, when needed, C++.
• Define and enforce best practices for Windows desktop development across the codebase, covering architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability.
• Drive accessibility efforts by integrating and validating support for accessibility APIs, ensure UI controls, focus management, keyboard navigation, screen-reader compatibility, and usability for users with disabilities.
• Collaborate closely with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and the long-term Windows platform roadmap.
• Own the full lifecycle of features—from conception and design through implementation, testing, release, and ongoing maintenance—to ensure quality and consistency across releases.
• Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, or compatibility problems, and propose robust architectural or design solutions.

• Proven track record shipping production-quality desktop applications with emphasis on reliability, performance, scalability, and maintainability.
• Strong experience with accessibility APIs on Windows (e.g., Microsoft UI Automation or similar), and a dedication to building accessible software.
• Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming where relevant.
• Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
• Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
