Principal AI Optimization Software Engineering Manager

**Overview**

The AI Frameworks Group builds the software foundation that enables Microsoft to deploy and run AI models efficiently across a rapidly evolving set of hardware platforms. Our mission is to ensure that every relevant AI model runs as efficiently as possible on every Microsoft AI accelerator. Because AI powers nearly every Microsoft product and service, our work directly shapes the performance, scalability, and profitability of the entire company. At Microsoft's scale, even modest efficiency gains translate into outsized infrastructure cost savings, making this one of the highest-impact engineering opportunities in the company.

We are looking for an accomplished engineering leader to build and lead the AI Optimization team: a group of expert engineers pushing the limits of AI performance through ML algorithm innovation, advanced AI compilation and hardware optimization, runtime and serving optimizations, and distributed execution.

In this role you will set the technical vision and strategy for AI optimization across Microsoft's AI hardware portfolio. You will own the roadmap, drive execution, and partner with senior leaders across model, systems, compiler, and hardware organizations to deliver step-change gains in performance, scalability, and efficiency for Microsoft's most critical AI workloads.
