Principal AI Back-End Network Systems Lead
Mountain View, CA - USA
Job Summary
Microsoft Silicon Cloud Hardware and Infrastructure Engineering (SCHIE) is the team behind Microsofts expanding Cloud Infrastructure and is responsible for powering Microsofts Intelligent Cloud mission. SCHIE delivers the core infrastructure and foundational technologies that support Microsoft Azure and other online services globally. Our focus is on smart growth high efficiency reliability and a trusted experience for customers and partners worldwide.
The Platform Systems Engineering (PSE) team is seeking a Principal AI Back-End Network Systems Leadto serve as the technical lead and end-to-end product development owner for Back End Network across both scale-up and scale-out. The role will lead the product from requirements and architecture through design integration validation manufacturing readiness deployment and fleet learning - spanning silicon network adapters switches interconnects optics/electrical channels and the fabric as a complete system.
The successful candidate will bring deep expertise in one or more AI/ML scale-up or scale-out networking domains and the product-level thinking to connect decisions across the full system. This lead will work from physical and data-link technologies through network and transport behavior to collectives workloads modeling observability and datacenter deployment creating clarity across architecture execution quality performance reliability power cost and schedule.
