Focus Areas

High Voltage/Pulsed Power Systems: Design, test, troubleshoot, support, and scale high-voltage systems for driving pulsed magnetic coils. Evaluate and apply solid-state switching devices (IGBTs, MOSFETs, SCRs/thyristors) with attention to losses, protection, di/dt, dv/dt, and thermal performance. Specify and integrate high energy components (capacitors, switches, pulse forming networks, buswork, protection, grounding).
Power Electronics: Design, test, scale, and integrate DC/DC, AC/DC, DC/AC converters used for energy delivery, energy recovery, and distribution ranging from hundreds of volts to thousands of volts. Develop switching-stage designs including half/full bridges, phase-shifted/full-bridge, LLC/series-resonant, or buck/boost-derived converters (topology selection based on efficiency, controllability, and fault behavior).
Low Voltage Control and Diagnostics: Design low voltage control electronics and PCBAs that interface with high energy systems. Own schematic capture and support layout, help scale PCBA deliveries to tens of thousands of boards. Build analog front ends for current/voltage/field/temp and other diagnostics: amplification, filtering, isolation, ADC interfacing. Ensure measurement integrity in high EMI environments (noise mitigation, grounding, shielding, calibration strategies). Partner with firmware/software teams on acquisition requirements and data quality.

Required Skills

2+ years experience in power electronics, solving complex electrical engineering problems from design to delivery.
Bachelor’s or Master’s level degree in Electrical Engineering, Physics, or a related technical field.
Demonstrated strength in at least one of the focus areas above.
Hands-on troubleshooting ability with standard lab equipment (oscilloscope, DMM, power supplies, loads, function/pulse generators, etc).
Comfortable working in high-energy or electrically noisy environments with strong safety mindset and disciplined documentation.
Experience with Microsoft Suite, LTSpice, SIMetrix/SIMPLIS, Simulink, Python, and/or MATLAB.

Benefits

Medical, Dental, and Vision plans for employees and their families.
31 Days of PTO (21 vacation days and 10 sick days).
10 Paid holidays, plus company-wide winter break.
Up to 5% employer 401(k) match.
Short term disability, long term disability, and life insurance.
Paid parental leave and support (up to 16 weeks).
