13 - Senior Principal, Design Engineering
Date:
Apr 18, 2026
Location:
San Jose, CA, US
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.
Detailed Description
Design power solutions for custom server & storage and Networking products using x86, ARM SoCs, DDR4/DDR5, NVMeoF, PCIe, RAID controllers and SAS. Drive power systems architectural direction for next generation devices & platforms
Defining power architectures, work with SI engineers to define SI constraints, Guide CAD designers and bring‑up and debug issues.
Set standards and achieve cost and performance for product
Make design choices, component selection and supplier selection.
RLC component selection, create and maintain the preferred list
DC relevant IC selection, create and maintain the preferred list
Manage BOM cost
Design maintain building block of DC relevant circuit, including BBU, except PSU. Base on specific requirement, including schematic and layout design
Architecture Lead and contribute to power delivery system architecture and specifications.
Design, analysis, and simulation of high current and low noise power delivery circuits.
Debug Contribute to system bring up, debug, and validation in the lab.
Verification Write and execute test and DVT plans.
10+ years industry experience, 5+ years power supply design experience
Familiar with the theory of buck, boost, buck‑boost, LDO, hotswap, oring, load switch, E‑fuse, fuel gauge, fuse transistor, diode cell and DC relevant parts and IC.
Familiar with Intel VR solutions like VR12.5 and VR13 design.
Well understand power efficiency optimization.
Experience of products development from prototype to mass production.
Proficiency in high efficiency DC‑DC power conversion design, analysis, circuit simulation, control loops, and stabilization.
Good understanding and skills to determine phase and gain margins
Proficiency in power design component selection and trade‑offs
Proficiency with Spice, LTspice, TI WorkBench, etc. circuit simulators
Experience in both high current low voltage multi‑phase (>500W) as well as ultra‑low noise power delivery circuitry
Proficiency in power supply layout and thermal design rules
Technical leadership of PCB layout with respect to various grounding and low noise etch techniques
Proficiency in power‑up sequencing in multi‑power supply systems
Designing interfaces with Processors, SPI & I2C devices
Ability to quickly grasp the existing designs and able to work independently with minimal supervision
Excellent verbal, written communication skills to produce Specifications and Test Plans
Experience in power supply design for leading edge high speed communication devices
Experience in power supply design for sensitive optical, switch, memory, NPU, CPU, GPU components
Failure mode analysis
Good understanding of power efficiency optimization schemes
Experience with Cadence Allegro and DxDesigner tools
Typical Education
Bachelor’s degree in Electrical Engineering, Master’s is preferred.
Educational Requirements may vary by Geography.
