Requirements

• Currently pursuing a Ph.D. in Electrical Engineering, with a graduation date no earlier than December 2026.
• At least 1 year of doctoral-level research experience in power electronics, electromagnetic modeling, or high-frequency magnetic design.
• Proficiency in electromagnetic FEA tools (e.g., Ansys Maxwell, FEMM, COMSOL) and circuit simulation tools (e.g., PLECS, LTspice, MATLAB/Simulink).
• Strong knowledge of electromagnetics, control theory, and semiconductor physics as applied to power conversion.

Nice To Haves

• Hands-on experience with PCB design tools (e.g., Altium, KiCAD) and building/testing power electronic hardware (>1kW).
• A proven track record of contributions to top-tier venues such as IEEE TPEL, TIE, APEC, or ECCE.
• Familiarity with high-frequency characterization equipment, including impedance analyzers and partial discharge test setups.

Responsibilities

• High-Density Converter Design: Develop and optimize power electronics topologies (e.g., resonant converters, multi-level stages) with a focus on extreme miniaturization and maximizing power density.
• Advanced Magnetic Modeling: Design and characterize high-frequency magnetic components, including planar, integrated, or novel configurations, to minimize volume and losses.
• Multi-Physics Simulation: Perform comprehensive modeling (electromagnetic, thermal, and dielectric) using finite element analysis (FEA) tools to predict performance and ensure reliability in compact designs.
• Insulation Coordination: Analyze and implement strategies to ensure dielectric integrity and compliance with safety standards in high-voltage, high-density systems.
• Hardware Prototyping: Lead the full hardware development process, including PCB layout, magnetic component fabrication, and complete converter assembly.
• Experimental Validation: Perform laboratory testing to evaluate efficiency, thermal management, and insulation performance under high-frequency operation.
• Technical Communication: Document research findings through technical reports and contribute to peer-reviewed publications or internal presentations.

Benefits

• Hired applicants may be eligible for benefits, including but not limited to, medical, dental, vision, life insurance, short-term disability, long-term disability, 401(k) match, flexible spending accounts, flexible work schedules, employee assistance program, Employee Scholar Program, parental leave, paid time off, and holidays. Specific benefits are dependent upon the specific business unit as well as whether or not the position is covered by a collective-bargaining agreement.
• Hired applicants may be eligible for annual short-term and/or long-term incentive compensation programs depending on the level of the position and whether or not it is covered by a collective-bargaining agreement. Payments under these annual programs are not guaranteed and are dependent upon a variety of factors including, but not limited to, individual performance, business unit performance, and/or the company’s performance.
