Electrical Engineer III

Summary:

We are seeking a highly motivated Electrical Engineer III to join our Engineering team with a strong focus on magnetic components design for power electronics applications. This role will contribute to the development of next-generation power modules by designing and optimizing inductors, transformers, and related magnetic components, as well as building component libraries and performing system-level simulations. The ideal candidate is hands-on, detail-oriented, and passionate about power electronics, with the ability to bridge component-level design and system-level performance validation.

• Design and develop magnetic components (inductors, transformers, and integrated magnetics) for power electronics applications with a focus on performance, efficiency, and manufacturability.
• Create and maintain a magnetic component library, including models, material properties, and design guidelines for internal reuse.
• Perform electromagnetic and system-level simulations (e.g., SPICE, Ansys Maxwell, Simplis, MATLAB) to evaluate power module performance and efficiency.
• Conduct detailed analysis of core loss, copper loss, thermal behavior, and electromagnetic fields to optimize designs.
• Prototype, test, and validate magnetic components using lab equipment (oscilloscopes, power analyzers, LCR meters).
• Perform system-level evaluation of magnetic components within power modules.
• Collaborate with cross-functional teams including power electronics, mechanical, and manufacturing teams.
• Prepare technical documentation, simulation reports, and test plans.
• Support design reviews and continuous improvement initiatives.

• Strong understanding of power electronics and magnetic component design principles.
• Experience with magnetic design tools (Maxwell, Ansys, SPICE, MATLAB or similar).
• Knowledge of inductor and transformer design.
• Hands-on lab experience.
• Strong problem-solving and teamwork skills.
• Ability to manage multiple tasks.

• Bachelor's degree in Electrical Engineering, Applied Physics and Materials Science or related discipline (Master's preferred). 2+ years of experience in power electronics or magnetics. Experience with magnetic component design, simulation, and testing preferred.
