Example projects include tooling that enable developers to efficiently use AI to refactor our large codebases at scale, perform package integrations automatically with AI, answer architectural questions about a codebase, make directed code changes with a human-in-the-loop approach, and other related problems. The authors of these codebases are also your customers! They are just down the hall enabling us to iterate quickly, get feedback, and bring required expertise together to make rapid progress.

We’re a growing team looking for a Senior Software Engineer for ES365 AI! In this role, you’ll be orchestrating the latest AI models to build tooling in service of Office productivity. You’ll lead through your own contributions to the codebase, form and advocate best practices and patterns to the team in this new field of AI development, and forge great technical and mission-based partnerships with other teams across Microsoft working on related problems in AI-powered developer productivity.
