About the role
As a Magnetics Design Engineer youll work closely with senior engineers to develop advanced models for ferrite-based magnetics while spending significant time in the lab performing hands-on measurements and experiments. Youll design and build test fixtures cut ferrite samples measure impedance and core losses and validate winding resistance and component performance against predictive models. Youll also collaborate with ferrite vendors and develop custom test fixtures to deploy innovative new test approaches.
This position is part of an advanced R&D team within the CTO Office and reports directly to the Sr. Director of Inverter Technology. Its an ideal role for a recent Masters graduate who is deeply interested in magnetic materials and eager to combine analytical skills with hands-on experimentation.

What you will do
- Design and validate ferrite-based magnetic components for advanced power conversion including inductors matrix transformers and integrated magnetics.
- Perform hands-on lab work: impedance and core loss measurements winding resistance checks and component assembly.
- Develop and refine custom test fixtures including PCB-based measurement systems using KiCAD.
- Cut ferrite samples prepare winding structures and execute precision measurements to validate material and component performance.
- Collaborate with senior engineers on magnetics modeling and simulation workflows.
- Work with ferrite vendors to evaluate material properties and integrate new materials into designs.
- Compare experimental results with predictive models and contribute to improving model accuracy.
Who you are and what you bring
- Masters degree in Electrical Engineering or a related field with a focus on magnetics or power electronics.
- Strong interest in high-frequency ferrite materials and magnetic component design (inductors matrix transformers integrated magnetics).
- Familiarity with a range of magnetic materials including ferrites (MnZn NiZn) powdered iron (MPP KoolMµ XFlux) nanocrystalline alloys (e.g. FINEMET Vitroperm) amorphous metals (Metglas) and silicon steel laminations.
- Understanding of dimensional effects in magnetic cores such as dimensional resonance and eddy current losses.
- Knowledge of advanced core loss modeling techniques including iGSE and emerging machine learning approaches from programs like Princeton MaGNET.
- Hands-on experience with lab measurements (impedance core loss winding resistance) and test equipment.
- Familiarity with PCB design tools (KiCAD preferred) for building custom test fixtures.
- Basic understanding of power electronics fundamentals; exposure to resonant converter topologies is a plus.
- Comfortable working in a fast-paced R&D environment with significant hands-on experimentation.
- Excellent attention to detail and a passion for bridging theory with practical validation.
