Overview
Azure Core powers the platform that runs Microsoft Azure, from datacenter infrastructure through the services that enable customers and Microsoft products to run at global scale. The Software-Defined Datacenter team combines distributed systems, machine learning, and cross-layer optimization to improve the efficiency of Azure's fleet, including Graphics Processing Unit (GPU) capacity used for artificial intelligence inference. You will work on initiatives that reduce inference cost, improve utilization, and unlock more serving capacity from existing GPU infrastructure in close partnership with Microsoft Research, Azure Artificial Intelligence engineering teams, and Azure Core platform teams.
As a Principal Software Engineer, you will be a hands-on technical leader for GPU efficiency. You will design, build, and operate cloud-scale systems that measure, model, and optimize inference workloads across Azure, translating research ideas into reliable production services. This opportunity will allow you to deepen your expertise in artificial intelligence infrastructure, distributed systems, and fleet-wide optimization while collaborating across research, hardware, and Azure Artificial Intelligence teams.
Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
Responsibilities
- Design, implement, and operate cloud-scale services that improve GPU inference efficiency, utilization, and cost across Azure.
- Partner with Azure Systems Research and Azure AI infrastructure teams to translate algorithms, models, and systems research into production-ready infrastructure.
