Do you want to be part of a team delivering innovative AI capabilities across flagship Microsoft products? Does the opportunity to lead a fast-paced, high-visibility, diverse team in a highly competitive market excite you? If so, this Principal Applied Science Manager role on the Microsoft Excel team is a great opportunity for you.

We are seeking an experienced Principal Applied Science Manager with a track record of building and shipping intelligent systems at scale. In this role, you will lead and develop a team of applied scientists responsible for architecting, designing, and delivering AI-powered experiences that help customers work more effectively in Microsoft Excel.

You and your team will apply state-of-the-art techniques in large language models, deep learning, information retrieval, agent orchestration, and evaluation. You will set the end-to-end scientific direction for Excel’s agentic AI and evaluation systems, translating customer needs, real-world usage patterns, and product failure modes into clear research, engineering, and product priorities - from early prototyping and experimentation through production deployment, evaluation, and ongoing service operation.

Microsoft’s customers use Excel as part of a broad suite of tools, and your role will expand to science work building key scenarios – such as finance - across the whole suite.

This is a deeply technical leadership role for a hands-on builder who can balance people management, technical strategy, and individual contribution. You will partner closely with engineering, product management, customers, and Microsoft’s broader AI, research, and platform communities to create trustworthy, high-quality AI applications that solve meaningful customer problems on a global scale.

The ideal candidate is passionate about maintaining a high scientific bar, building inclusive and high-performing teams, and delivering reliable, customer-impacting AI capabilities.
