Speechify is a text-to-speech platform used by over 50 million people to convert PDFs, books, Google Docs, articles, and websites into audio. The company was named Chrome Extension of the Year by Google and received Apple's 2025 Design Award for Inclusivity. With ~200 employees globally in a fully distributed setting, Speechify is hiring a Senior Software Engineer to lead Windows desktop application development. In this role, you will own the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI, C#, XAML, and C++ as needed. You'll define best practices for Windows development across the codebase, focusing on code architecture, performance, memory efficiency, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability. Key responsibilities include driving accessibility efforts by integrating and validating Windows accessibility APIs (Microsoft UI Automation), ensuring proper focus management, keyboard navigation, and screen-reader support. You'll collaborate with product designers, UX researchers, QA, and stakeholders to shape feature planning and the long-term Windows platform roadmap. You'll take full ownership of feature lifecycles from conception through design, implementation, testing, release, and maintenance, ensuring quality and consistency across releases. You'll also identify and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, and compatibility problems, proposing robust architectural solutions. Required qualifications include 3+ years of Windows desktop application development with Windows App SDK, WinUI, C#, and XAML, plus ideally native Windows code experience (C++, Win32/WinRT/COM). You need deep understanding of Windows application architecture and interop between managed and native code. A proven track record of shipping production-quality desktop applications emphasizing reliability, performance, and maintainability is essential. Strong experience with Windows accessibility APIs and dedication to inclusive software is required. You should have excellent software engineering fundamentals (OOP, design patterns, data structures, algorithms, memory management, multi-threading), experience leading technical design and mentoring engineers, and strong communication skills. A user-centric mindset is critical. Bonus qualifications include experience with automated UI testing, performance optimization for desktop apps, localization/globalization, telemetry and analytics, CI/CD workflows for desktop applications, and demonstrated ability to own feature areas long-term.
