Job Level

Lead

About the role

  • Responsible for architecting, implementing, and supporting power system solutions for Networking, storage & server systems and related products.
  • 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 drive system architecture of multi-tiered power network design from rack level power distribution down to the board level POL solution.
  • 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.

Requirements

  • 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.
Benefits
