Principal Product Manager

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As Microsoft accelerates its AI-first strategy, platform efficiency and cost discipline have become foundational enablers for sustainable growth of Microsoft 365 and Copilot experiences. The M365 Core Platform Performance & Scale PM team owns the end-to-end efficiency and cost optimization strategy across the Microsoft 365 substrate. We are looking for a Principal Product Manager to lead Microsoft 365 Core Platform Efficiency and COGS Savings, spanning the multiple efficiency workstreams—including Azure infrastructure, telemetry, Copilot workloads, and platform-wide optimization, not limited to any single fleet type. This role is strategically critical to Microsoft’s AI roadmap. As AI workloads scale rapidly, this position ensures that Microsoft can deliver AI innovation at global scale while maintaining financial sustainability, margin health, and operational excellence.
