Principal Software Engineer, Foundry Agents CoreAI

Microsoft Foundry is building the foundational platforms that power the next generation of intelligent agents and generative AI systems. WithinCoreAI theFoundry Agents organizationis responsible for key ownership areas across theendtoendagent lifecycle:(a) Foundry Agents platformto deploy and run agents securely at enterprise scale with seamless integration with governed tools(b) modelfinetuningto train and improve agentic performance and(c) Foundry observabilityto generate insights from agentic traces and continuously evaluate and optimize agents.

As a senior engineer within Foundry Agents you will help build and evolvelargescalecloudnativesystems that span the full lifecycle of advanced agentic applications from secure enterprise deployment and governed tool integration tofinetuningand training loops to deep observability evaluation and optimization in production. Your work will directly shape how developers and enterprises build reliable autonomous andhighimpactAI agents.

You willoperateat the intersection ofdistributed systems AI infrastructure and developer platforms owning architectural decisions for complex systems that must meet the highest standards of performance reliability security and compliance. This role requires deep technical judgment strong systems thinking and the ability to translate evolving customer developer and research needs into durable platform capabilities.

Across the organization you will:

• Build and scale foundational services that power secure agent deployment and execution governed tool integration training/finetuning and observability/evaluation

• Design and evolve distributed runtimes and cloud services to run agents securely at enterprise scale with strong reliability security and compliance guarantees

• Improve iteration loops for researchers engineers and developers through better tooling abstractions and automation acrossfinetuning evaluation and optimization

• Debug andoptimizecomplex interactions across models data hardware and infrastructure

• Drive technical direction across the full software development lifecycle influencing design tradeoffs and longterm architecture

• Champion operational excellence securebydesign practices and responsible AI at scale

• Collaborate closely with partner teams acrossCoreAIand Azure to deliver seamless productionready platforms

As a senior technical voice you will raise the engineering bar throughstrong designprinciples rigorous reviews mentorship and influence across yourwork will help define how intelligent agent systems are builtoperated and trusted shaping how the world interacts with AI.
