Amazon Hires Ex-Microsoft Copilot CTO

Amazon AWS hired Pedram Rezaei as a Distinguished Engineer on October 5, joining its Agentic AI and Emerging Technologies group.

Rezaei spent over two decades at Microsoft, most recently serving as Copilot's CTO until June and working on foundation model training within the Superintelligence team. He will initially focus on bolstering Quick, AWS's AI assistant, and Kiro, its AI-powered coding tool. Internal emails note rapid growth for these products: Kiro's user base doubled in Q2, while Quick's monthly AI users grew fourfold.

This hire signals Amazon's strategy to acquire top-tier technical talent from competitors to accelerate the deployment of widely used AI agent products.
