Chuck Walbourn
Senior Software Engineer at Microsoft
Redmond, Washington, United States
Summary
🤩
RockstarChuck Walbourn is a Senior Software Engineer with 11 years of experience based in Redmond, Washington, focused on low-level C++ systems for graphics, audio, and tooling across DirectX and Xbox ecosystems. At Microsoft he has contributed to high-profile projects like DirectXTK, DirectXTex, DirectXMesh, FX11 and vcpkg, improving performance, cross-compiler compatibility, and robustness in production graphics code. His work spans audio engine prototypes, BC7 compressor optimizations, and fixes for memory and compiler issues, reflecting deep expertise in performance-sensitive, platform-specific engineering. He often operates at the intersection of systems engineering and developer tooling—porting libraries, updating headers, and modernizing legacy DirectX samples for Windows 10 and UWP. Colleagues would note his attention to subtle correctness issues (SAL annotations, memory access fixes) and a knack for making low-level subsystems more usable, such as adding abort/ESC handling to tooling.
