Senior Principal, Design Engineering - Power

Summary

Responsible for architecting, implementing, and supporting power system solutions for Networking, storage & server systems and related products. 
In this position you will help develop hardware solutions to be integrated into common platform designs including processors, high speed serial interfaces, NPUs, FPGAs, High speed memory (DDR4/DDR5) and high-speed PCB layout. You will work with design, software/firmware, mechanical and thermal engineers. You will lead the design of DC-DC switch-mode power supplies and component selection. The successful candidate will work across disciplines to assure power supply designs meet the power, thermal, and safety requirements of the system specification. You will work closely with Celestica multi-disciplinary engineering and manufacturing teams to understand the system requirements and contribute or lead the specification, design, and debug of complex power delivery systems for datacenter products.
