Summary

the pitch

Join our team as a Senior Software Engineer specializing in Windows/Desktop Applications. You will lead the design, architecture, and development of native Windows desktop applications, define best practices for Windows desktop development, drive accessibility efforts, collaborate with cross-functional teams, and take ownership of the full lifecycle of features. The ideal candidate will have 3+ years of experience in Windows desktop application development, a user-centric mindset, excellent software engineering fundamentals, and strong communication skills.

Role

posted by company
  • 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)
  • A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users
  • 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
  • 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
  • Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software
  • 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
  • Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions
  • Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load)
  • Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks

Key responsibilities

  • 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.
