Software Engineer II, Foundry Agents - CoreAI

Microsoft Foundry is building the foundational platforms that power the next generation of intelligent agents and generative AI systems. Within CoreAI, the Foundry Agents organization is responsible for key ownership areas across the endtoend agent lifecycle: (a) Foundry Agents platform to deploy and run agents securely at enterprise scale with seamless integration with governed tools, (b) model finetuning to train and improve agentic performance, and (c) Foundry observability to generate insights from agentic traces and continuously evaluate and optimize agents.

As a Software Engineer II within Foundry Agents, you will contribute to building largescale, cloudnative systems that support the full lifecycle of advanced agentic applications - from secure enterprise deployment and tool integration, to finetuning workflows, to observability and evaluation in production. Your work will help enable developers and enterprises to build reliable and effective AI-powered agents.

You will work as part of a team at the intersection of distributed systems, AI infrastructure, and developer platforms, implementing components that meet high standards for performance, reliability, security, and compliance. This role is ideal for engineers who are strong coders, eager to learn, and excited to grow their expertise in large-scale systems and AI platforms.

Microsoft's mission is to empower every person and every organization on the planet to achieve more. We bring that mission to life through a culture that values growth mindset, diverse perspectives, and continuous learning. Join us and help build the platforms that will power the next generation of AI-driven applications.
