Job description

We are seeking an experienced Power Electronics Engineer with strong expertise in high-power AC/DC and DC/DC power conversion systems. The ideal candidate will have hands‑on experience with power electronics design, system‑level debugging, and collaboration with firmware, mechanical, and test teams.

Key Responsibilities

• Architect and design high-power AC/DC and DC/DC systems for consumer and commercial EV chargers.
• Design and develop 40–100 kW soft‑switching converters and multi‑level converters up to 2000 VDC.
• Develop 100–200 kW grid‑tie inverters and four‑quadrant power conversion systems.
• Perform power electronics design including schematics, PCB layout, magnetics, thermal design, component selection, modeling, and DFM.
• Work with power topologies including LLC, Phase‑Shifted Full Bridge, Flyback, Forward, Multilevel Converters, and PFC.
• Apply ZVS/ZCS and other soft‑switching techniques.
• Model and simulate power designs using PLECS, MATLAB/Simulink, and SPICE.
• Support digital control development using DSPs, FPGAs/PLDs, and embedded software.
• Collaborate closely with firmware, mechanical, thermal, test, and validation teams.
• Perform system‑level debugging and resolve issues from architecture through laboratory testing and validation.
• Ensure product reliability under demanding electrical and environmental conditions.
• Support regulatory, compliance, and industry‑standard requirements.

Required Qualifications

• M.S. in Electrical, Electronics, Computer, or related Engineering; PhD preferred.
• 10+ years of power electronics product development experience preferred, with flexibility for strong candidates with less experience.
• Strong experience in high‑power AC/DC and DC/DC power conversion.
• Strong electrical design and system‑level engineering skills.
• Hands‑on experience with power electronics hardware development and debugging.
• Experience working cross‑functionally with firmware, software, mechanical, thermal, and test teams.
• Experience bringing power electronics products from concept through production.
• Knowledge of consumer and industrial electrical standards.
• EV charging standards experience is a plus.
• Experience with EV, energy storage, solar, or grid‑connected power systems is highly preferred.
