M365 Copilot inference is a high-impact engineering team advancing applied AI and large-scale machine learning across Microsoft. We design and operate the platform powering Microsoft 365 Copilot experiences.

Our team is operating at massive GPU (Graphics Processing Unit) scale across multiple regions and SKUs in global datacenters. We build the core LLM (Large Language Model) API (Application Programming Interface) , routing, capacity, and control plane services that turn that fleet into Copilot experiences.

We are hiring a Principal Group Software Engineering Manager to own GPU fleet health, capacity intake and planning, and automated model deployment for Copilot. This is one of the most strategic leadership roles in Copilot: every feature, experiment, and model launch flows through the systems this leader owns. You will lead existing teams, grow the org, and build the control plane that turns capacity management from a manual, ticket-driven pro...
