Senior Software Engineer, Fauna
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 end‑to‑end agent lifecycle: (a) Foundry Agents platform to deploy and run agents securely at enterprise scale with seamless integration with governed tools, (b) model fine‑tuning 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 large‑scale, cloud‑native systems that support the full lifecycle of advanced agentic applications — from secure enterprise deployment and tool integration, to fine‑tuning workflows, to observability and evaluation in production. Your work will help enable developers and enterprises to build reliable and effective AI-powered agents.
