Speechify is seeking a Senior Software Engineer to lead the design, architecture, and development of native Windows desktop applications. This fully remote role is based in Sofia, Bulgaria, and you will work with Windows App SDK, WinUI, C#, XAML, and, when needed, C++. You will establish and enforce best practices for Windows desktop development across the codebase, focusing on architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability. You will drive accessibility efforts by integrating and validating support for accessibility APIs (such as Microsoft UI Automation), ensuring UI controls, focus management, keyboard navigation, screen-reader support, and usability for users with disabilities. You will collaborate with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and the long-term roadmap for the Windows platform. You will own the full lifecycle of features—from conception to design, implementation, testing, release, and maintenance—ensuring quality, reliability, and consistency across releases. You will identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, or compatibility problems, and propose robust architectural or design solutions. Ideal candidates have: at least 3 years of Windows desktop app development using Windows App SDK/WinUI (or similar), with C#, XAML, and ideally experience with native Windows code (C++, Win32/WinRT/COM). Deep understanding of Windows app architecture, including interop b
