  • Lead accessibility efforts by integrating and validating support for accessibility APIs, ensuring proper focus management, keyboard navigation, screen reader compatibility, and inclusive usability.
  • Collaborate with product designers, UX researchers, QA, and stakeholders to shape feature planning, UI/UX architecture, and the Windows platform roadmap.
  • Own the full lifecycle of features from conception through design, implementation, testing, release, and ongoing maintenance to ensure quality and reliability across releases.

  • Proven track record delivering production-quality desktop applications with emphasis on reliability, performance, scalability, and maintainability.
  • Strong experience with Windows accessibility APIs (Microsoft UI Automation or similar) and a commitment to accessible software.
  • Solid software engineering fundamentals: object oriented programming, design patterns, data structures, algorithms, memory management, and concurrent or asynchronous programming as applicable.
  • Experience leading technical design, mentoring engineers, conducting code reviews, and making architecture-level decisions.
  • Excellent communication skills, capable of articulating tradeoffs, collaborating across cross-functional teams, and driving consensus.
  • User-centric mindset focused on delivering polished, intuitive, and accessible experiences for end users.
