  • Utilize your scientific experience and knowledge to invent new topologies, determine root causes of challenging issues, and contribute to other projects,
  • Design, evaluate and support various leading-edge high performance, cost-effective reference DC-to-DC converters that exemplify the superior characteristics of eGaN FETs, including instructional collateral generation and design for manufacturing (DFM) reviews,
  • Participate in the definition of new GaN devices by testing new GaN devices in DC-to-DC converter applications and provide feedback on improvements,
  • Provide technical guidance and mentor team members,
  • Help establish new and efficient design procedures,
  • Support sales and marketing teams,
  • Write and publish world-class technical documents, journals, and books that explain the excellence of your work.


  • Design of DC-to-DC switching converters and topologies, with computing and automotive systems, background a plus,
  • Familiarity with switching devices, gate drivers, and digital control is a plus
  • Experience in debugging hardware issues and understanding root cause failure,
  • Experience with layout (Altium preferred) and PCB design process of digital, analog, and power converter systems. Knowledge of IPC specifications is a plus,
  • Practical bench experience: testing and setting up experiments, data processing, and document generation, soldering and rework, modification of boards and, mechanical assembly,
  • High-frequency, digital, RF, highly resonant wireless power, and high-density design experience is a plus,
  • Publishing, seminar, tutorial, and other educational experience in English,
  • Project leadership and ownership experience with the ability to meet tight schedule deadlines.


  • Expert in the field of Power electronics and switching converters, with in-depth knowledge of DC-to-DC switching converters and topologies,
  • Good understanding of analog circuit design, semiconductor testing, and thermal aspects of converters,
  • Proficient in design capture and analysis software: schematics, PCB layout (Altium preferred), simulations (e.g., LTSpice)
  • Good understanding of magnetic component design, operation, and use,
  • Ability to understand high-level industry trends based on discussions with customers on their requirements for the new product generation,
  • Good listening, verbal, written, and interpersonal communications skills.
