Senior Power Electronics Engineer

Responsibilities

• Design, analyze, simulate, prototype, and validate power conversion systems and topologies.
• Develop and implement both analog and digital control loops.
• Create and maintain technical documentation, including product specifications, schematics, and interface control documents.
• Conduct design reviews and collaborate cross-functionally with Engineering, Manufacturing, and Quality teams.
• Support product transition to manufacturing, including design for manufacturability and test readiness.
• Troubleshoot and resolve complex issues in production and field environments.
• Mentor and support the development of team members, contributing to a culture of continuous improvement.

Requirements

• Bachelor’s degree in Electrical Engineering with 8+ years of power conversion experience OR a Master’s degree with a focus in Power Electronics and 6+ years of power conversion experience.
• Proven experience designing power conversion systems, including active front-end designs for single and three-phase AC inputs.
• Strong understanding of isolation requirements, including creepage and clearance standards (UL, IEC).
• Experience with EMI/EMC design, compliance, filtering, and troubleshooting.
• Deep knowledge of power semiconductor devices (MOSFETs, SiC, GaN), gate drivers, and protection circuits.
• Proficiency in analog and power circuit simulation tools (e.g. LTspice).
• Strong foundation in control theory, including design, modeling, and stability analysis of control loops.
• Experience with thermal design and analysis (heatsinking, airflow, and loss modeling).
• Knowledge of magnetics design, including transformers and inductors (core selection, winding techniques).
• Experience with isolated and non-isolated bidirectional topologies (DAB experience strongly preferred).
• Hands-on experience with lab instrumentation (oscilloscopes, power supplies, electronic loads, network analyzers).
• Demonstrated success bringing products from concept through volume production.
• Strong collaboration and communication skills with the ability to work effectively across teams.
