About the role

  • Architect and design the power supply and board-level power delivery network (PDN) for accelerator cards and related platforms:
  • o Define power trees, rails, sequencing, and margining
  • o Select VRMs, DC‑DC converters, controllers, FETs, magnetics, and protection components
  • o Investigate PCB technology options and define power delivery strategies for high-current, low-voltage environments
  • Enable the supply chain and work with suppliers over the full lifecycle
  • Perform schematic design for power stages and collaborate with layout engineers to ensure proper placement, routing, and copper utilization for high‑current paths.
  • Work closely with PI/SI engineers on PDN impedance, decoupling strategies, and transient performance.
  • Specify and guide power-on sequencing, monitoring, and telemetry (PMBus, I2C, etc.).
  • Conduct lab validation of power subsystems:
  • o Efficiency, ripple, transient response, stability
  • o Load/line regulation and thermal performance
  • Lead debug of power-related issues (e.g., startup failures, droop, noise coupling, OCP/OVP events).
  • Collaborate with silicon, hardware, system, reliability, and manufacturing teams to ensure design-for-reliability (DFR) and design-for-manufacturability (DFM) of power solutions.
  • Generate design documentation, test plans, and bring‑up procedures.

Requirements

  • Bachelor’s and Master’s degree in Electrical Engineering or related field.
  • 5+ years of experience in board-level power design for high-performance or server-class systems.
  • Strong understanding of:
  • o Switching power converters (buck, multiphase, POL regulators)
  • o Power topologies, compensation, and stability
  • o High-current layout techniques and loss optimization
  • Hands-on experience with schematic capture (e.g., Siemens Xpedition) and familiarity with PCB layout constraint definition.
  • Proficiency with lab equipment (oscilloscopes, electronic loads, power analyzers, DMMs).
Benefits
  • Join an innovative team and experience company growth.
  • We believe in investing in our employees and providing them with the opportunities they need to grow and develop their careers.
  • Enjoy a hybrid work environment.
  • We also offer flexible schedule.
  • We offer a remuneration that values your experience.
