Senior Software Engineer, Windows/Desktop Applications - Fresno, CA, USA

Role overview

This position focuses on building native Windows desktop applications using modern frameworks such as the Windows App SDK and WinUI. The role combines hands-on engineering with technical leadership, setting architectural direction and shipping features end to end for a product used at scale. It is a senior individual contributor role with significant influence on the Windows platform's roadmap and on engineering quality standards across the codebase.

Responsibilities

- Design, architect, and develop native Windows desktop applications using Windows App SDK, WinUI (or comparable UI frameworks), C#, XAML, and C++ when needed. - Establish and maintain engineering best practices for Windows desktop development, including performance, memory usage, responsive UI, cross-version compatibility across Windows 10/11+, and long-term maintainability. - Drive accessibility initiatives by integrating platform accessibility APIs, validating focus management, keyboard navigation, screen-reader support, and inclusive UI patterns. - Partner closely with product designers, UX researchers, QA, and product stakeholders to plan features and shape the long-term Windows roadmap. - Own the full feature lifecycle from conception and design through implementation, testing, release, and ongoing maintenance. - Diagnose and resolve complex bugs, rendering issues, memory leaks, performance bottlenecks, and compatibility problems, proposing robust architectural fixes.

Requirements

- Three or more years of professional experience building Windows desktop applications with Windows App SDK, WinUI (or similar), C#, and XAML, plus working knowledge of native code such as C++, Win32, WinRT, or COM. - Deep understanding of Windows application architecture and managed-to-native interop on .NET. - Demonstrated track record of shipping production-quality desktop software with attention to reliability, scalability, and performance. - Hands-on experience with Windows accessibility APIs (for example, Microsoft UI Automation or equivalents) and a commitment to inclusive design. - Strong software engineering fundamentals, including object-oriented design, design patterns, data structures, algorithms, memory management, and asynchronous programming. - Experience leading technical design, mentoring engineers, conducting code reviews, and making architecture-level decisions. - Clear written and verbal communication skills, with the ability to articulate tradeoffs and build consensus across teams. - User-centric mindset focused on polished, intuitive experiences.

Nice to have

- Experience writing automated UI tests (unit, integration, and UI automation) using relevant testing frameworks. - Background in desktop performance optimization, including startup time, memory footprint, high-DPI rendering, and responsiveness. - Familiarity with localization, right-to-left UI support, internationalization, and accessibility across multiple regions. - Comfort with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications. - Hands-on work shaping CI/CD workflows, release pipelines, and deployment strategies for desktop software.

Benefits and work setup

- High-impact role with direct influence over the architecture and future direction of the Windows product. - Collaborative, flat engineering culture that treats senior engineers as builders and decision-makers. - Opportunities to mentor, steer technical direction, and grow toward tech lead or architect responsibilities. - Fully remote, distributed work environment with high autonomy and end-to-end feature ownership. - US-based compensation: $140,000–$200,000 USD per year, plus bonus and equity, depending on experience.
