About The Position

We are reimagining the marketing research discipline by building AI-powered tools that help researchers and data scientists move from question to insight faster. We’ve already delivered millions in cost savings for Microsoft and are scaling the next generation of intelligent, production-ready capabilities. In this role as a Data Scientist, you will design, build, and operate AI-enabled applications on top of our marketing research data ecosystem. You’ll partner closely with product, engineering, and research stakeholders to translate real user needs into secure, reliable experiences—bringing strong software engineering fundamentals (architecture, coding, testing, and deployment) plus applied AI expertise (LLMs, retrieval, evaluation, and monitoring). You’ll join a collaborative team that values clear problem statements, thoughtful trade-offs, and continuous learning. Our work spans the spectrum from rapid MVPs and prototypes to hardened, scaled production services—always with clear criteria for quality, security, and user impact. You will have room to focus deeply, iterate with users, and ship improvements end-to-end—from prototype to production—while measuring impact with well-defined quality and adoption metrics.
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.
