David Williams-young is a Principal Quantum Software Engineer with nine years of experience bridging high-performance computing, computational chemistry, and production software—now leading mixed quantum-classical software efforts at Microsoft Quantum from Los Angeles. He built and scaled open-source exascale tools (GauXC, ExchCXX, IntegratorXX, MACIS) and helped make ChronusQ and NWChemEx go-to packages for advanced electronic-structure simulation on DOE leadership-class systems. Comfortable across the stack, he pairs deep numerical methods and GPU-accelerated Krylov algorithms with pragmatic engineering practices to deliver community-adopted libraries. An active open-source contributor, he also makes front-end improvements to popular projects like the Oni editor, showing a rare blend of low-level HPC expertise and attention to user-facing UX.
