Copilot Developer Jobs in California (NOW HIRING)

Overview

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.

About the Team

We build the cross-cutting capabilities that shape the future of human-AI interaction. Our work spans modalities-text, voice, vision, action-and pushes the boundaries of what intelligence can do in people's lives. We partner deeply with design, product, and applied AI to ship extraordinary 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 AIcompanion: ubiquitous, always capable, always there. We're building for a future where AI doesn't just respond-it acts, creates, and orchestrates.

About the Role

You'll build revolutionary experiences at the intersection of modality and intelligence. The pace is fast. The ambiguity is high. You'll ship things that millions of people use-and you'll ship things 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 want to define the future of how humans and AI live and work together, come build with us.

Responsibilities

• Create breakthrough experiences that redefine what an AI companion can do

• Build across modalities-voice, vision, text, and action-to make Copilot feel seamless and alive

• Own features end-to-end, from concept through production, at scale

• Collaborate with applied AI researchers to bring cutting-edge model capabilities to users

• Ship experiments rapidly, learn from usage, and iterate toward experiences that feel like magic

• Work across team boundaries on problems that span the entire product
