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.

About the team:
The Microsoft Applied Sciences Group incubates disruptive technologies for Microsoft’s Experiences and Devices organization. We are working on groundbreaking technologies that shape how we will interact and communicate with computers, each other and our environment. Operating as a startup within the company, our team works closely with several research and product teams to bring compelling new experiences to the market. A lot of these experiences will be powered by machine learning – and as part of this team, you will be uniquely positioned to bring latest research to life in products that are used by hundreds of millions of people.
