Senior Software Engineer; Windows​/Desktop

Responsibilities

• Lead the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI (or related UI frameworks), C#, XAML, and — when needed — C++
• Define and enforce best-practices for Windows desktop development across the codebase: code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability
• Drive accessibility efforts: integrate and validate support for accessibility APIs (e.g. Microsoft UI Automation or other relevant Windows accessibility frameworks), ensure UI controls, focus management, keyboard navigation, screen-reader support, 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 long-term roadmap for the Windows platform
• Take ownership of full lifecycle of features: conception → design → implementation → testing → release → maintenance. Ensure quality, reliability, 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
• A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience
• A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker
• Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect)
• Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision
• A purpose-driven mission: building software that’s reliable, accessible, and user-centered — making a real difference for people

• Proven track record of designing, building, and shipping production‑quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability
• A user‑centric mindset: focus on building polished, intuitive, and accessible experiences for end users
• 3+ years in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML — and ideally additional experience with native Windows code (C++, Win
  32/WinRT/COM)
• Strong communication skills; ability to articulate tradeoffs, collaborate with cross‑functional teams, and drive consensus
• Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code
• Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture‑level decisions
• Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software
• Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi‑threading or asynchronous programming (where relevant)
• 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)
• Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications
• 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
