Principal Product Manager - M365 Messaging

Microsoft Microsoft · Big Tech · Redmond, WA +1 · Product Management

Principal Product Manager for the Microsoft 365 Messaging team, focusing on the conversation store platform that powers Copilot across Microsoft 365. The role involves owning the strategy and roadmap for how Copilot and agents persist, load, and reason over conversations, including notifications and tasks. It requires driving convergence towards a unified schema, championing enterprise trust, and ensuring operational health for a large-scale distributed system at the center of Microsoft's AI strategy.

What you'd actually do

  1. Own the platform vision and roadmap for the conversation store for Copilot and agents — defining the durable primitives (conversations, threads, intermediate agent outputs, reasoning traces, tasks, notifications) that all Copilot scenarios build on.
  2. Drive conversation-store convergence toward a unified schema: separate intermediate agent outputs and reasoning traces to improve conversation loading and unlock client-side pagination, align storage and schema, and converge real-time transport (multi-endpoint presence, streaming) across surfaces.
  3. Lead the Copilot Notifications charter — evolve the extensible, end-to-end notification pipeline, prioritize notifications across products to reduce overload, and give users control through notification settings that re-engage them across mobile, email, and in-app.
  4. Scale the Tasks platform — mature first-class task representation across Copilot surfaces and Teams; enable a unified task hub as the control tower for AI work; and evolve toward an agent-to-agent (A2A) task-compatible interface.
  5. Champion enterprise trust — own compliance, auditability, data lifecycle, and large-message support, preventing data leakage and unintended duplication as conversations grow richer.

Skills

Required

  • Bachelor's Degree AND 8+ years experience in product/program management or software development OR equivalent experience.
  • Ability to meet Microsoft, customer and/or government security screening requirements.

Nice to have

  • Bachelor's Degree AND 12+ years experience in product/program management or software development OR equivalent experience.
  • 4+ years experience taking a product, feature, or experience to market
  • 6+ years experience improving product metrics for a product, feature, or experience in a market
  • 6+ years experience disrupting a market for a product, feature, or experience
  • Demonstrated ownership of a platform or infrastructure-adjacent product at scale, including setting strategy that multiple partner teams adopted.
  • Track record of translating complex partner and customer requirements into durable, reusable platform capabilities — not one-off integrations.
  • Proven ability to drive cross-organizational technical strategy and alignment, influencing without authority across engineering and product teams.
  • Solid written and verbal communication skills, with the ability to frame architectural tradeoffs for both engineers and executives
  • Experience with large-scale distributed systems — messaging, storage, pub/sub, or notification platforms (e.g., distributed NoSQL databases, event delivery pipelines).
  • Familiarity with AI / Copilot orchestration, agentic workflows, or large language model conversation modeling (e.g., intermediate agent outputs, reasoning traces, multi-agent scenarios).
  • Experience evaluating and driving non-functional requirements

What the JD emphasized

  • own the strategy and charter
  • set the multi-year vision
  • drive its execution
  • own compliance, auditability, data lifecycle
  • cross-organization alignment and adoption
  • guide them toward reusable platform capabilities rather than parallel one-off stores
  • Represent the platform in leadership reviews
  • build alignment across teams that do not report to you

Other signals

  • Copilot is our fastest-growing workload as agentic, multi-step AI experiences become first-class.
  • own the strategy and charter to establish the conversation store as the platform of choice for all Copilot scenarios
  • set the multi-year vision for how Copilot and agents persist, load, and reason over conversations
  • drive its execution across one of the largest distributed systems at Microsoft
  • 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.
