Job summary

Enphase Energy in Petaluma, CA is seeking a technically deep power electronics engineer to advance the Solid-State Transformer platform. You will design high-density power modules, optimize efficiency, and reduce cost per watt across the SST family.

Join a team that collaborates with mechanical, thermal, and controls engineering to optimize packaging, cooling, and reliability. Applicants should have earned BS+3 yrs, MS+1, or PhD with hands-on hardware experience and proficiency in ECAD tools.

Qualifications

• BS, MS, or PhD in Electrical Engineering or closely related field.
• Typically, 4+ years of electronics hardware/system design experience.
• Hands-on experience in schematic capture, layout, and testing of power electronics.
• Proficiency with ECAD tools such as OrCAD, KiCad, or Altium.
• Ability to translate modeling and simulation to benchtop performance.
• Experience co-designing power electronics with mechanical and thermal teams.

Responsibilities

• Design and develop power conversion circuits and magnetics for the SST platform, optimizing power density, efficiency, and thermal performance.
• Evaluate and integrate advanced power semiconductor devices (GaN) and planar magnetics to increase power throughput while shrinking module footprint.
• Translate modeling and simulation results into benchtop prototypes, reconciling differences between predicted and measured performance.
• Drive design trade-offs across power density, efficiency, thermal management, and cost per watt to meet next-generation targets.
• Co-design with mechanical and thermal engineering to optimize packaging, cooling, and power density, and collaborate with controls engineering to integrate power modules into the SST platform.
• Lead root-cause analysis and design iteration based on test data to improve power density and reliability.
