• 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), 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.
• Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, or compatibility problems, and propose robust architectural or design solutions.

• 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).
• Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code.
• Proven track record of designing, building, and shipping production‑quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability.
• Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation) 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.
• 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.
• 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.
• Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.
• Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.
• Demonstrated ability to take ownership of feature areas or modules and drive them long‑term, including maintenance, refactoring, and technical debt management.

• 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.

US Based Salary range for this role is: 140,000‑200,000 USD/Year + Bonus + Stock depending on experience.
