Summary
👤
Senior🎓
Top SchoolHarry Mallon is a pragmatic software engineer and release/configuration specialist with a decade of experience building high-performance, hardware-integrated systems for cinema and cloud environments. He progressed through senior engineering and team lead roles at CODEX, where he led a distributed team to deliver an unannounced product (‘SD’), designed its software spec, and shipped device control APIs and multi-platform clients. His hands-on expertise spans C++, Python, Rust, Swift, Typescript and build systems, and includes GPU work (Metal/CUDA), Linux ARM devices, and kernel driver delivery. An active contributor to notable open-source projects like CMake and OpenImageIO, he has improved build tooling and added AVIF/HEIF support and iOS/Xcode build features. Now at Apple as a Config/Release Engineer, he combines deep systems-level engineering with release automation and cross-functional delivery skills. Colleagues describe him as a technical generalist who comfortably moves between low-level performance work and product-facing APIs.
