  • 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.
  • Take ownership of full lifecycle of features: conception → design → implementation → testing → release → maintenance.
  • Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, or compatibility problems.

  • Proven track record of designing, building, and shipping production-quality desktop applications.
  • Strong experience with accessibility APIs on Windows.

  • Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.

Preferred / Bonus:

  • Experience with writing automated tests for UI.
