Senior Software Engineer (Windows/Desktop Applications)

Join our team as a Senior Software Engineer specializing in Windows/Desktop Applications. In this role, you will lead the design, architecture, and development of native Windows desktop applications. You will define and enforce best practices for Windows desktop development, drive accessibility efforts, and collaborate closely with product designers, UX researchers, QA, and other stakeholders. You will take ownership of the full lifecycle of features, ensure quality and reliability across releases, and identify and resolve complex bugs and performance issues. The ideal candidate will have a deep understanding of Windows application architecture, strong communication skills, and a proven track record of designing and shipping production-quality desktop applications.

• Lead the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI, C#, XAML, and C++.
• Define and enforce best-practices for Windows desktop development across the codebase, including code architecture, performance, memory usage, and maintainability.
• Collaborate closely with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and long-term roadmap for the Windows platform.
• Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code
• Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus
• Proven track record of designing, building, and shipping production-quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability
• 3+ in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML — and ideally additional experience with native Windows code (C++, Win32/WinRT/COM)
• Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions
• Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming (where relevant)
• Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software
• A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users
• Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks
• Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load)
• Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions
• Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management
• Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications
• Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications
