Senior Power Electronics Engineer, Oklahoma City

The Role
My client is at the forefront of new technology development within the cleantech sector.
They are building novel hardware which is a cheaper and more efficient than current solutions in the space.
They have recently completed their first deployable unit and are already starting on their next.
They are looking for a Power Electronics Engineer with a builder's mindset, someone motivated by hands-on development, testing, and iteration.
You should be as comfortable holding a soldering iron and probing circuits with an oscilloscope as you are working in simulation software.
You will:
Rapidly prototype resonant converter topologies (LLC, dual active bridge, and beyond) for electrolysis systems
Wind custom inductors and transformers using in-house CNC winding equipment, pushing the limits of magnetics design
Troubleshoot high-voltage, high-frequency circuits in a lab environment, learning from each iteration
Contribute to hardware bring-up, from breadboard to final product, working closely with mechanical and chemical engineers
Take ownership of power-stage design, including PCB layout, thermal management, and EMI mitigation
Key Responsibilities
1. Resonant Converter Design
Architect and optimize LLC, dual active bridge, and other resonant converter topologies
Simulate designs using LTSpice, PSpice, or Simulink and validate through lab testing
2. High-Voltage Switching & SMPS
Develop high-efficiency switch-mode power supply (SMPS) solutions
Design high-voltage, high-side switching circuits
Address EMI challenges and optimize multi-layer PCB layouts
3. Magnetics Design & Prototyping
Design and wind custom transformers, inductors, and coils using CNC winding tools
Evaluate core materials such as ferrite, amorphous, and nanocrystalline materials to optimize performance
4. Hands-On Prototyping & Testing
Conduct lab testing using oscilloscopes, network analyzers, and spectrum analyzers
Diagnose failures, refine designs, and iterate rapidly
5. Thermal Management & Packaging
Design for reliable and safe operation, including heatsinks, airflow, insulation, and packaging
Validate thermal performance through simulation and experimental testing
6. Cross-Functional Collaboration
Work closely with mechanical, chemical, and firmware engineering teams
Clearly communicate complex electrical concepts to cross-disciplinary teams
Qualifications
Education
Bachelor's or Master's degree in Electrical Engineering (Power Electronics focus preferred)
Coursework or research in resonant power conversion, high-frequency design, or electrochemical systems is a plus
Experience
2–5+ years of experience in power electronics or power supply design
Experience designing and testing SMPS, high-voltage circuits, and magnetics
Comfortable working in both lab and manufacturing environments
Experience taking products from prototype through certification (UL, CE) is a plus
Technical Skills
Proficiency in LTSpice, PSpice, or MATLAB Simulink
PCB design experience using KiCad or Altium
Hands-on experience with oscilloscopes, spectrum analyzers, and network analyzers
Strong understanding of thermal design, EMI mitigation, and electrical safety
Culture and Work Environment
Hands-on, hardware-focused mindset
Comfortable working in fast-paced, early-stage environments
Passionate about clean energy and technology development
Strong communicator able to collaborate across technical disciplines
