Senior Power Electronics Engineer

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

Why Join

• Work at the cutting edge of sustainable energy innovation.
• Access to in-house prototyping tools, including CNC winding equipment, enabling rapid iteration and hardware development.
• Experimentation is encouraged. The team embraces rapid learning through hands-on engineering.
• Your work will contribute directly to reducing carbon emissions and advancing clean energy technologies.
