Principal Product Manager - Copilot Extensibility DevX
About The Position
Microsoft 365 is seeking a Principal Product Manager to shape how builders prove, understand, and continuously improve the quality and value of Copilot plugins. The role owns strategy and roadmap for customer-facing plugin evaluations and quality measurement, providing builders and owners with evidence that plugins work, meet quality standards, deliver value, and offer actionable improvement guidance. The Product Manager 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 Observability and Analytics product leader, the role will connect evaluation findings with production signals to provide an end-to-end view of plugin value and support decisions to improve, scale, consolidate, or retire plugins. The position turns ambiguous developer and platform needs into durable product direction, leads complex evaluation and quality-measurement decisions, and aligns engineering, applied science, design, security, compliance, and partner teams. It defines evaluation contracts and feedback loops connecting pre-production evidence, the developer journey, and production signals to support continuous, evidence-driven improvement across Microsoft’s Copilot ecosystem.
Requirements
- Bachelor’s degree and 8+ years of experience in product/service/program management or software development, or equivalent experience.
- Experience with AI or LLM evaluation, including nondeterministic outputs, LLM-as-judge methods, human-rating calibration, multi-step agent or tool-use evaluation, dataset development, or offline-to-online measurement.
- Experience defining product strategy and leading developer platforms, extensibility systems, AI products, or evaluation capabilities from concept through launch and sustained adoption.
- Demonstrated data-driven product management using evaluation findings, telemetry, customer feedback, adoption, or business-value signals to prioritize investments and measure outcomes.
- Experience partnering with engineering on platform architecture, APIs, SDKs, extensibility models, data systems, or production services.
- Hands-on software development or equivalent experience building prototypes and integrations using APIs, SDKs, or AI-assisted development tools.
- Experience building products for technical audiences and translating developer needs into clear requirements, roadmaps, and measurable outcomes.
- Experience influencing senior product and engineering stakeholders and leading complex technical initiatives across organizations without direct authority.
Nice To Haves
- Bachelor’s degree and 12+ years of experience in product management, service management, program management, software development, or a related field, or equivalent experience.
Responsibilities

- Establish quality and Responsible AI models, regression protections, and release criteria for groundedness, prompt injection, harmful content, reliability, and performance.
- Build evaluation into CLI and IDE workflows, CI/CD, and publishing so developers can create evaluation sets, interpret results, identify gaps, and improve plugins.
- Connect evaluation findings with production telemetry, adoption, support, customer, and business-value signals through a shared scorecard that guides investments.
- Validate product concepts through AI-assisted prototypes and translate them into architecture, APIs, reusable components, integration contracts, and clear engineering handoffs.
- Represent the strategy and lead cross-organizational decisions, balancing developer value, platform reuse, responsible delivery, cost, and speed.
