Description

Lead the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI, C#, XAML, and sometimes C++.
Define and enforce best practices for Windows desktop development, including code architecture, performance, memory usage, UI responsiveness, compatibility, and maintainability.
Drive accessibility efforts by integrating and validating support for Windows accessibility APIs and ensuring keyboard, focus, and screen-reader usability.
Collaborate with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and the Windows roadmap.
Own features end to end from conception through design, implementation, testing, release, and maintenance.
Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, and compatibility problems.
Lead technical design discussions, mentor other engineers, and contribute to architecture-level decisions.
Maintain quality, reliability, and consistency across releases.
Propose robust architectural or design solutions to improve the desktop experience.

Requirements

3+ years of experience in Windows desktop application development using Windows App SDK, WinUI or similar frameworks, C#, and XAML.

Deep understanding of Windows application architecture, including interoperability between managed .NET code and native code.
Proven experience designing, building, and shipping production-quality desktop applications with an emphasis on reliability, performance, scalability, and maintainability.
Strong experience with accessibility APIs on Windows, such as Microsoft UI Automation or similar frameworks.
Solid software engineering fundamentals, including OOP, design patterns, data structures, algorithms, memory management, and multithreading or asynchronous programming.
Experience leading technical design, mentoring engineers, conducting code reviews, and making architecture-level decisions.
Strong communication skills and the ability to articulate tradeoffs, collaborate cross-functionally, and drive consensus.
User-centric mindset focused on polished, intuitive, and accessible end-user experiences.
Experience with automated UI testing, performance optimization, localization/internationalization, telemetry, crash reporting, or CI/CD workflows is preferred.

Benefits

Salary range of $140,000 to $200,000 USD per year, plus bonus and stock, depending on experience.
Opportunity to define architecture and shape the future of a product used by millions of people.
Collaborative, flat-structure engineering culture with room to influence technical decisions.
