Top SchoolMazz Mosley is an engineering manager with 17 years of experience leading platform and software teams across startups and scaling organisations, currently managing two web product teams at Overstory. He builds high-performing, multi-disciplinary teams through clarity, coaching, and measurable outcomes, and has hands-on experience with Kubernetes, Terraform, ArgoCD, AWS and optimisation engines like OR-Tools. Previously he scaled platform and scheduler teams at Automata, led engineering at Weaveworks and Lyst, and has a track record of hiring managers and codifying engineering practices (including an Engineering Handbook and transparent salary bands).
