Principal Product Manager - M365 Messaging

The Microsoft 365 Messaging team builds and operates the trusted, secure, intelligent, and scalable messaging and notification platform that powers Copilot across Microsoft 365. We are the connective tissue behind Copilot’s conversations and notifications — the platform that lets Copilot connect, converse, remember, notify, and continue the thread across Microsoft 365 Enterprise and Consumer Copilot, Microsoft Teams, Outlook and beyond. We operate at extraordinary scale, and Copilot is our fastest-growing workload as agentic, multi-step AI experiences become first-class. As a Principal Product Manager on the team, you will own the strategy and charter to establish the conversation store as the platform of choice for all Copilot scenarios — and to extend that platform into the connected areas of Notifications and Tasks. You will set the multi-year vision for how Copilot and agents persist, load, and reason over conversations, then drive its execution across one of the largest distributed systems at Microsoft. This is a high-influence, high-ownership role for a builder who can operate from first-principles strategy down to schema-level technical tradeoffs, at the center of Microsoft’s AI strategy. Our mission is to make Copilot the most trusted, effective communicator in the enterprise: reaching users wherever they are, remembering every conversation, and acting as a true partner to get work done. Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
