Senior Applied Scientist

** Overview*
* The Copilot Offline Evaluation Platform (COEP) team provides the evaluation data, environments, and capabilities that Microsoft Copilot product teams use to make faster, more confident release decisions. We are seeking a Senior Applied Scientist to improve how well offline evaluations represent and predict real customer experiences. You will develop scientific methods for extracting representative query and intent patterns from Copilot traffic, generating high-quality synthetic evaluation data, measuring and improving query-set and tenant representativeness, reproducing customer dissatisfaction scenarios as compliant evalsets, and increasing alignment between offline evaluation results and online shadow experiments.

You will partner closely with engineering, product, and research teams to turn these methods into scalable capabilities used across Copilot, including evaluation of long-running agents and generative AI systems.

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.
