How do you know an AI product is actually getting better—and how do you prove it at scale, before millions of people experience the difference?
We build and operate the offline evaluation platform that gates Microsoft Copilot’s quality. Teams across Copilot depend on us to run their scenarios against the product, score the responses, and produce the scorecards that inform what ships. We do this at the scale of one of the world’s largest AI products, within a strict enterprise compliance boundary. As Copilot evolves into a fleet of autonomous agents, the way we measure quality must evolve with it—and you will lead that transformation.
As a Principal Software Engineer on the Copilot evaluation team, you will own the technical vision for a platform built AI-first and agent-first: one where autonomous agents are not only measured, but also help operate, extend, and heal the system itself.
You will take on our hardest problem: delivering trustworthy results across a deep chain of dependencies—including Copilot’s model, retrieval, and scoring services—that we push far beyond their normal operating envelope, with hundreds of calls per job under relentless and growing load. You will architect how we evaluate agentic Copilot experiences, from multi-turn trajectories and tool selection to end-to-end task outcomes, and set the standard for how the broader product defines and measures quality.
This opportunity will allow you to shape the evaluation strategy for one of the world’s most visible AI products, work at the frontier of large-scale agentic systems and reliability engineering, and grow your influence as a technical leader across a large engineering organization.
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.
