Kuy Mainwaring is an engineering manager with 13 years of experience leading cross-disciplinary teams to build reliable embedded systems and high-performance machine learning infrastructure. He currently manages a large Google team responsible for XLA, the ML compiler that optimizes PyTorch, TensorFlow and JAX models to run efficiently on GPUs and TPUs. His background spans founding hardware-focused startups, shipping consumer IoT products (from smart locks to kitchen appliances), and writing ultra-low-power firmware and OTA update systems. Kuy combines systems-level architecture with hands-on firmware and tooling experience—he once built an open-source microcontroller platform and a JavaScript IDE that brought full-source debugging to low-cost boards. Known for shipping pragmatic, safety- and reliability-focused firmware in constrained environments, he brings that discipline to optimizing ML toolchains at scale from his base in San Francisco.
