Principal Product Manager

M365 Core Platform | United States 

Shape the platform & infrastructure strategy behind M365 and Copilot. This role takes on the hardest technical and strategic problems spanning storage, performance and scale, fleet and capacity, and LLM infrastructure, connecting decisions across the stack into a coherent platform strategy. 

The M365 Core Platform team is hiring a Principal Product Manager to lead high-impact initiatives across Storage Fabric, Performance & Scale, Fleet & Capacity, and LLM API. This is a broad role for someone who can move fluidly across these systems, go deep quickly, and drive problems that do not fit neatly within a single team. 

AI is changing how infrastructure needs to be built and operated. Demand moves at software speed while physical capacity moves at infrastructure speed. Models, hardware, and workloads change continuously. Storage, compute, GPUs, routing, caching, reliability, efficiency, and product policy are increasingly interconnected. 

As a Principal Product Manager, you will take on a small number of the organization's highest-impact strategic problems at a time. You will develop the technical and product thesis, understand the system and its constraints, identify architectural choices and tradeoffs, align teams around a direction, and drive the work to measurable customer, capacity, performance, or efficiency outcomes. 

This is an AI-first product management role. You will use AI agents, automation, data analysis, and rapid prototyping to investigate problems, test hypotheses, model tradeoffs, and accelerate decisions. The role requires systems thinking, technical depth, product judgment, and the ability to operate with significant ambiguity and autonomy. 

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.

• Lead strategic and technical initiatives spanning Storage Fabric, Performance & Scale, Fleet & Capacity, and LLM API, particularly where solutions require changes across multiple layers of the platform.
• Take ambiguous, high-impact infrastructure problems from first principles through strategy, architecture, roadmap, execution, and measurable results.
• Develop a system-level view of how storage, compute, GPU capacity, models, inference infrastructure, routing, caching, reliability, and product policy interact, and identify opportunities across organizational boundaries.
• Shape how M365 and Copilot scale, including workload portability, infrastructure utilization, capacity allocation, and reducing resources required per customer outcome.
• Connect demand, supply, workload characteristics, model efficiency, infrastructure efficiency, and economics to drive capacity and investment decisions.
• Identify architectural simplifications and platform investments that remove structural bottlenecks rather than repeatedly solving individual performance, capacity, or reliability problems.
• Use telemetry, experimentation, modeling, and AI-driven analysis to quantify opportunities, test hypotheses, and measure outcomes.
• Anticipate changes in models, hardware, workloads, and AI architectures and translate them into platform requirements and investment priorities.
• Work across engineering leaders, architects, product teams, and infrastructure organizations to establish direction and drive complex initiatives through execution.
• Define success metrics and communicate complex technical and economic tradeoffs to senior leaders in a way that enables decisions.
• Mentor PMs and technical leaders and raise the organization's ability to reason about infrastructure as an interconnected system. 

• Bachelor's Degree AND 10+ years experience in product/service/program management or software development
  • OR equivalent experience.
