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 and enforce best practices across the codebase for performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability. A key focus is driving accessibility: integrating and validating support for Microsoft UI Automation, ensuring proper focus management, keyboard navigation, screen-reader support, and usability for users with disabilities.
You'll collaborate closely with product designers, UX researchers, QA, and other 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. You'll 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). You need deep understanding of Windows application architecture, including interop between managed and native code, and a proven track record shipping production-quality desktop applications. Strong experience with Windows accessibility APIs and a dedication to inclusive software is essential. You should have excellent software engineering fundamentals, experience leading technical design and mentoring engineers, and strong cross-functional communication skills.
Preferred experience includes automated UI testing, performance optimization for desktop apps, localization/globalization, telemetry and crash reporting, CI/CD workflows for desktop applications, and demonstrated ability to own feature areas long-term.
