Amazon Hires Veteran Microsoft AI Executive to Build Coding and Workplace Tools
Pedram Rezaei, a nearly 20-year Microsoft veteran who previously served as Copilot’s chief technology officer, has joined Amazon Web Services as a distinguished engineer. The move places him at the center of AWS’s bid to compete with Microsoft and other tech giants in the fast-growing market for AI-powered coding and workplace productivity tools.
Rezaei starts in the AWS Agentic AI and Emerging Technologies organization, which is led by Swami Sivasubramanian. He will work initially on Kiro, AWS’s coding assistant, and Quick, Amazon’s AI assistant for workplace tasks, according to a memo Sivasubramanian wrote to his team.
“He is a hands-on engineer who is still in the code every day, and he plans to keep it that way here,” Sivasubramanian wrote, characterizing Rezaei’s approach as deeply technical rather than managerial.
A Track Record Across Microsoft’s Biggest Products
Rezaei joined Microsoft in 2006 and held senior technical roles on Power BI, Dynamics 365, Cortana, Bing, and Azure Maps before moving to Copilot, according to his LinkedIn profile. He became Copilot’s CTO in February 2026 and moved to the Microsoft Superintelligence team in June, where he was most recently working on training foundation models.
His departure is part of a broader pattern of AI talent moving between the two companies. Shawn Bice returned to AWS in May from a security role at Microsoft to lead its Automated Reasoning Group. Additionally, two longtime AWS engineers, Marvin Theimer and Reto Kramer, returned from Microsoft to work on neurosymbolic AI and automated reasoning, which Sivasubramanian called “one of our biggest bets for the future.”
Neurosymbolic AI pairs large language models with rule-based systems that can verify whether an AI agent is following a company’s policies and procedures, an approach that addresses one of the key concerns enterprises have about deploying AI tools in production environments.
The Competitive Landscape for AI Coding Tools
The hire comes as Amazon and Microsoft compete more directly in AI tools for work. Microsoft last month unveiled an all-in-one Copilot app that combines chat, coding, and agents, its answer to offerings from OpenAI and Anthropic. Amazon made its Quick desktop app generally available in September and brought its main features to mobile.
According to Sivasubramanian’s memo, Kiro’s user count doubled from the first quarter to the second, and monthly AI users for Quick grew fourfold. Rezaei’s plan for his first few months is to “meet people, learn how things work here, and ship something real.”
Sivasubramanian’s organization was expanded in July to include emerging technologies, part of a broader reshuffling of Amazon’s AI teams that reflects the company’s recognition that AI tools for developers and knowledge workers represent a significant growth opportunity.
What Rezaei’s Hiring Signals About AWS’s AI Strategy
The decision to bring in a senior executive with deep experience in Copilot’s development suggests that AWS is serious about competing in the AI coding assistant market, which has been dominated by Microsoft through its GitHub Copilot product. By hiring someone who helped shape Copilot’s technology vision, AWS is effectively trying to import expertise from its chief rival.
Rezaei’s background in foundation model training also aligns with AWS’s investments in custom AI infrastructure and its partnerships with leading AI labs. The company has been building out its Trainium chip lineup and expanding its Bedrock platform, which provides access to models from multiple providers.
For developers and enterprises, the competition between AWS and Microsoft in this space is likely to accelerate innovation and drive down costs, as both companies race to offer the most capable and affordable AI tools for building and running software.
The coming months will reveal whether Rezaei’s move translates into tangible product improvements for Kiro and Quick, and whether AWS can close the gap with Microsoft in a market that is evolving rapidly and attracting new entrants on a regular basis.
