As Microsoft continues to push the boundaries of AI, we are on the lookout for passionate individuals to work with us on the most interesting and challenging AI questions of our time. Our vision is bold and broad - to build systems that have true artificial intelligence across agents, applications, services, and infrastructure. It’s also inclusive: we aim to make AI accessible to all - consumers, businesses, developers - so that everyone can realize its benefits.

We build the cross-cutting capabilities that shape the future of human-AI interaction. Our workspans modalities-text, voice, vision, action-and pushes the boundaries of what intelligencecan do in people’s lives. We partner deeply with design, product, and applied AI to shipextraordinary experiences that define what Copilot becomes.The problems we solve don’t fit neatly into one layer of the stack or one corner of the org-which is exactly what makes them interesting. Our mandate is to make Copilot the essential AI companion: ubiquitous, always capable, always there. We’re building for a future where AIdoesn’t just respond-it acts, creates, and orchestrates.

As a Principal Full-Stack Software Engineer on our AI Experiences, Copilot Engineering team, you’ll build revolutionary experiences at the intersection of modality and intelligence. The paceis fast. The ambiguity is high. You’ll ship things that millions of people use-and you’ll shipthings that don’t exist anywhere else yet.

If you want to work on well-scoped problems with clear answers, this isn’t the team. If you wantto define the future of how humans and AI live and work together, come build with us.
