**Overview** Are you a **Software Engineer** already at the forefront of agentic AI development - someone who uses agents to build software today and wants to build the platform that brings those capabilities to every developer at Microsoft? Do you have strong opinions about what great agentic tooling looks like, formed from real experience shipping with it? Do you want to dogfood the very platform you're building and have your own productivity transformed by it? If so, we'd love to talk with you about this opportunity! Our AI team is a part of the larger ES365 (Microsoft 365 Engineering Systems) team - and we own the agentic engineering platform being adopted across all of Microsoft. ES365 owns the tools and systems used by thousands of Microsoft developers who innovate across the company's largest codebases, from source control and check-in experience to build, validation, and deployment automation. This gives us a unique position to define what AI-powered developer productivity looks like at Microsoft scale. The ES365 AI team is 100% focused on pushing that frontier. We build the agentic platform itself and the experiences on top of it. The developers and codebase owners who use these tools are your customers, just down the hall - giving us a tight feedback loop and the domain expertise to move fast. For additional context, example workstreams have included AI-assisted large-scale codebase refactoring, automated package integrations, deep architectural Q&A over codebases, and human-in-the-loop directed code changes. We're a growing team looking for a passionate **Software Engineer** . In this role, you'll help define and build the next generation of our agentic platform, orchestrating the latest AI models and harnesses in service of company-wide developer productivity. You'll lead through excellent contributions to the ESAI codebase, advocate best practices for agentic development, and forge technical and mission-based partnerships with other teams across Microsoft working on related problems. If you are excited about AI's potential and want to be on the front lines of AI-Powered developer efficiency at Microsoft, we want you in ES365 AI.
