Overview
We are the People Experiences team within the M365 AI Experiences organization, and the creators of People Agent, one of the most visible and transformative features in Microsoft 365 Copilot. We're not just building another productivity tool; we're transforming the way people engage and connect in their relationships at work.
You’ll help shape the AI-assisted Person View, a dynamic profile that brings together everything that matters about your collaborators: recent chats, shared docs, meetings, and personal insights, into one intelligent, actionable space. This is the front door to relationship intelligence in Copilot, and your work will be seen and used by millions of users across Outlook, Teams, Copilot, and more.
As a Senior Software Engineer you’ll work on:
- Declarative agent architecture that powers Copilot’s understanding of people.
- Prompt grounding and memory systems that personalize responses and enable proactive preparation.
- Tune the backend systems to surface real-time insights from across M365.
- UX innovations that blend model-forward intelligence with rich GUI affordances.
We move fast, iterate weekly, and care deeply about building tools that help people enhance collaboration and deepen relationships. If you’ve ever wished your software could help you remember what matters about your relationships, then this is the team to join.
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.
