Christopher Coleman-smith is a Staff Software Engineer with 17 years of experience designing and maintaining large-scale distributed storage systems, currently at Waymo after leading Colossus maintenance at Google. He began as a physics researcher with a PhD from Duke, bringing rigorous modeling and statistical calibration skills to complex systems engineering problems. A former Site Reliability Engineer for Bigtable and Senior Performance Engineer at Akamai, he combines deep operational experience with low-level programming enthusiasm to optimize performance and reliability across massive clusters. Christopher excels at bridging theory and production—applying numerical methods and probabilistic emulation techniques from his academic work to real-world storage and networking incidents. Based in Stony Stratford, England, he is known for shepherding distributed storage lifecycles and tackling both high-impact incidents and subtle hardware-level faults.
