Senior Director of Power Systems Engineering

Overview

Senior Director of Power Systems Engineering — Santa Clara, CA (On-site / Lab-focused).

This hands-on role involves the design, implementation and validation of high-efficiency AC/DC and DC/DC converters for next-generation data center architectures. You will work with a team of systems and applications engineers to deliver high-power density solutions ranging from kilowatt (kW) rack-level systems to hundreds of kW cluster-level architectures. The ideal candidate blends hardware topology design/architecture with advanced digital control to power cutting-edge AI, GPU, and CPU hardware.

This is a senior role with high visibility requiring extensive interaction with management and cross-functional teams (Device Engineering, System Applications, Packaging).

• High-Power Design
  :
  Architect and build AC/DC front-ends and DC/DC converters handling kilowatt to hundreds of kW power blocks.
• Topology Innovation
  :
  Design high-efficiency, high-density topologies (e.g., interleaved PFC, LLC, dual active bridge, phase-shifted full bridge, ISoP converters) to meet stringent, evolving data center power delivery specifications.
• Hardware Development
  :
  Component selection, thermal-conscious schematic capture, and multi-layer PCB layout optimization. Collaborate with applications engineering for debug, simulation and validation of converter specs.
• Custom Magnetics Engineering
  :
  Design and model discrete and planar in-PCB magnetics for high-frequency operation. Partner with magnetics vendors to specify, iterate, and manufacture custom magnetic components.
• Digital Control Implementation
  :
  Develop, code, and tune digital control loops for real-time power conversion and telemetry.
• Compliance & Validation
  :
  Direct EMI/EMC mitigation strategies and validate systems against grid and safety standards.

• Education
  :
  Master’s or PhD degree in Electrical Engineering with a power electronics specialization.
• Experience
  : 5+ years in high-power switch-mode power supply (SMPS) design or grid-tied conversion.
• Semiconductor Expertise
  :
  Hands-on design experience with SiC and GaN wide-bandgap devices, and their gate-drivers, isolators and sensing circuits.
• Digital Control Platforms
  :
  Experience programming microcontrollers for power electronics (e.g., TI C2000, STM
  32, or FPGA).
• Simulation Tools
  :
  Proficient in PLECS, Simplis, MATLAB/Simulink or LTspice for system-level analysis of AC/DC and DC/DC converters.
• Advanced Architecture
  :
  Knowledge of 48V and 800V/±400V DC bus distribution frameworks common in hyperscale environments.
• Standards
  :
  Familiarity with Open Compute Project (OCP) power specifications and 80 Plus Titanium efficiency requirements.
