BSEE Min. | MSEE Preferred

Build real power hardware. Solve real engineering problems. Ship products that matter.

We are seeking a hands-on Principal Power Electronics Engineer to design and bring to production high-power inverter and energy conversion systems used in demanding industrial environments. This role requires a builder-minded engineer who thrives at the bench—debugging hardware, solving real-world problems, and driving designs from concept through release and in-field performance support .

You will take ownership of power architecture, hardware development, and product delivery ,ensuring designs perform not only in the lab but in real-world applications over time.

If you’ve spent your career bringing converters to life, chasing down EMI and thermal issues, and seeing your designs successfully deployed in the field—we want to talk.

This is not a simulation, modeling or management role. This is a builder’s role.

Advanced degrees are valued, but do not substitute for practical, hands-on experience. Candidates whose experience is primarily simulation, modeling or management will not be a fit.

★ Bi-Directional Inverter/Charger:
Hands-on design & development of high-power bi-directional topologies — schematic through tested hardware

★ AC Ratings: 120

VAC–575

VAC line voltages, up to 200A — proven in shipped products

★ DC Ratings: DC bus voltages up to 480

VDC, DC currents up to 400

ADC in product environments

★ Power Topologies:
Full-Bridge, Flyback, Buck, Boost — hard-switching and resonant/quasi-resonant, hands-on bench experience

★ Magnetics & Transformers: HF ferrite and LF laminated steel transformer design — core selection, winding, prototype build and test

★ Passive Components:
Intimate knowledge of electrolytics, film caps, inductors, and resistors — derating, parasitics, failure modes

★ Thermal Design:
Passive and forced air cooling techniques

★ Battery System Integration:
Direct experience with power electronics interfacing battery systems — charge/discharge control, Li-ion, LFP, lead-acid

★ Analog & Digital Circuits:
Mixed-signal design integrated into power conversion systems

★ Microchip Embedded:
Hands-on experience with Microchip PIC or dsPIC microcontrollers for real-time power conversion control — device configuration, peripherals, and firmware debug

★ C / Assembly Programming:
Must have personally written and debugged embedded firmware in C or machine-level assembly — not just modified existing code

★ Bench Troubleshooting:
Expert daily use of DVMs, oscilloscopes, and differential probes for hardware bring-up and fault diagnosis

★ Simulation: LTspice or equivalent SPICE tools for converter modeling and pre-build validation

→ in-field performance support

★ Design battery-interfaced power converters up to 480

VDC / 400

ADC

★ Build and test power transformers — HF ferrite and LF laminated steel
