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 recently 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 applications using Windows App SDK, WinUI, C#, XAML, and C++ as needed. You'll define best practices for Windows desktop development across the codebase, focusing on code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability.
A key responsibility is driving accessibility efforts—integrating and validating support for accessibility APIs like Microsoft UI Automation, ensuring proper UI controls, 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, UI/UX architecture, 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; deep understanding of Windows application architecture and interop between managed and native code; proven track record shipping production-quality desktop applications; strong experience with Windows accessibility APIs; 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 analytics, CI/CD workflows for desktop applications, and demonstrated ability to own feature areas long-term.
