  • Generate and release documents for designs, assembly, acceptance-testing, manufacturing etc.
  • Assist other electrical engineers in designs and testing of analog and digital circuits
  • Perform failure analysis on new and returned systems from the field


  • US Citizen or Permanent Resident
  • 6+ years in design of AC/DC and DC/DC converter topologies that includes flyback, buck, boost, buck-boost, half- and full-bridge, ZVS, multi-phase, etc.
  • 5-10 years experience designing high power (kW and above), high-voltage (>100V) DC/DC power conversion
  • Subject matter expert on tradeoffs of power MOSFET, IGBTs, SCRs, diodes and semiconductor technologies including GaN and SiC
  • Great understanding of power and mechanical design tradeoffs between high-voltage, power, weight, space, environmental, safety, thermal, etc.
  • Designed high-reliably power supplies from the ground-up used in demanding applications
  • Extensive implementation experience of thermal management for high-power semiconductors
  • Experience with control systems, analog compensation, PID, firmware control, etc. used in power supply circuitry
  • Strong experience in complex system integrations
  • Experience dealing with revisions to requirements and schedule in a dynamic environment
  • Experience working with CAN, RS232, RS485, Ethernet bus communication and I2C, SPI, UART embedded protocols
  • Good understanding of testing EMI and mitigation techniques for EMC


  • Worked in AS-9100, ISO-9001, DoD, MIL-STD related regulatory environments
  • Implementing MCU and/or FPGA firmware for power applications
  • Startup experience is helpful
  • Hands-on, cable assembly, wiring crimping, machine shop experience
  • Understanding of different battery cell electrochemistry and the electronics that go into a battery management system


  • Use the best design tools for work including custom CAD workstations with SpacePilot Pro 3D mice, FirePro GPU’s, and 27" IPS LCD displays
  • Ongoing education such as conferences, workshops, and books/subscriptions
  • Onsite meals, snacks, ping pong, basketball and foosball
  • Competitive benefits, matching 401k and Tuition reimbursement
