Software Engineer II - Office AI Platform

Microsoft 365 Copilot is a groundbreaking productivity tool that leverages the power of large language models, user data, Microsoft Graph, and the web to drive unparalleled creativity and productivity. At the heart of this innovation is the Office AI team, which plays a crucial role in the development of Copilot experiences across M365 and an expanding list of partners across Microsoft. We own the infrastructure that enables complex orchestration of M365 Copilot workflows to put powerful AI capabilities at the user’s fingertips, as well as the chat user experience and horizontal skills, and extends across Word, Excel, PowerPoint, OneNote, and an expanding list of partners across Microsoft. As a Software Engineer II on the Office AI Platform team, you spend most days designing and implementing changes to core feature and platform components that power Copilot across Office apps. You review telemetry to understand how your features behave in production, debug issues across client and service boundaries, and iterate with partner teams to land integrations cleanly. You write and review code, add or refine instrumentation, update tests and build pipelines, and contribute to drive root‑cause investigations when something breaks. Your work alternates between building new platform capabilities and strengthening the reliability, performance, and security of existing ones so Copilot scenarios run consistently at Microsoft scale.
