Microsoft 365 is seeking a Principal Product Manager to shape how builders prove, understand, and continuously improve the quality and value of Copilot plugins. You will own the strategy and roadmap for customer-facing plugin evaluations and quality measurement, giving builders and owners clear evidence that a plugin works, meets the intended quality bar, and delivers value and actionable guidance on what to do next.
A plugin is a unit of Copilot extensibility that packages skills, connectors or MCP capabilities, and agents into a capability that can be discovered, invoked, and used consistently across products. As plugins become central to connecting AI experiences with enterprise data, tools, and business processes, builders and owners need a clear view of whether each plugin works, is being used, and delivers value.
You will define an adaptive strategy for evaluation experiences and quality measurement across the plugin lifecycle, from pre-production evaluation through continuous improvement. In partnership with the plugin DevX architect and the Observability and Analytics product leader, you will connect evaluation findings with production signals to give builders and owners an end-to-end view of plugin value and a shared flywheel to improve, scale, consolidate, or retire plugins.
As a Principal Product Manager, you will turn ambiguous developer and platform needs into durable product direction, lead complex evaluation and quality-measurement decisions, and align engineering, applied science, design, security, compliance, and partner teams around shared outcomes. You will define the evaluation contracts and feedback loops that connect pre-production evidence with the end-to-end developer journey and production signals, moving the ecosystem from isolated testing to continuous, evidence-driven improvement.
This is an opportunity to define a foundational capability for Microsoft’s copilot ecosystem, influence how plugin quality is measured across Microsoft experiences, and make it dramatically easier for developers to ship reliable, secure, high-quality AI extensions with confidence.
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. We build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
