Description
OverviewThe AI Transformation team within Microsoft Frontier Company is reimagining how the company operates in the age of AI. We work across the business to transform critical end-to-end workflows, bringing people, AI agents, and systems together to create fundamentally new ways of working.Our team brings together engineering, applied AI, program leadership, and business transformation to move rapidly from opportunity to working solution. We operate with a builder mindset: hands-on, highly collaborative, comfortable with ambiguity, and biased toward action. Our goal is not simply to add AI to existing processes, but to build AI-native operating models and reusable solutions that improve how Microsoft Frontier Company works and accelerate transformation at scale.

You’ll work in small, multidisciplinary teams to experiment rapidly, evaluate approaches, and turn data and emerging AI capabilities into agents, models, and decision systems that deliver measurable operational impact.
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.
