Job Title: Power Electronics Engineer
Location: Cambridge, UK
Industry: Power Electronics / Advanced Energy Systems
Employment Type: Full-time / Permanent
Overview:
We are seeking a highly skilled and motivated Power Electronics Engineer to join our client's innovative team in Cambridge. The successful candidate will play a key role in the design and development of cutting-edge power conversion systems, leveraging wide-bandgap semiconductors and high-frequency magnetics for next-generation applications.
Key Responsibilities:
- Lead the design and optimisation of planar magnetics, including PCB winding layout and electromagnetic simulation for high-density power converters.
- Design and test high-voltage LLC DC-DC converters operating above 500V, ensuring high efficiency and compact form factor.
- Work extensively with 650V and 1200V SiC and GaN devices, including selection, thermal management, and performance characterisation.
- Develop high-frequency gate driver circuits (up to 1 MHz) and associated auxiliary power supplies to support robust and fast switching.
- Perform simulation, schematic capture, PCB layout supervision, and prototype testing across the full development lifecycle.
- Collaborate with mechanical, thermal, and firmware teams to deliver integrated system solutions.
- Support DVT, EMC compliance, and safety certification processes as required.
Key Requirements:
- Degree (Master’s or PhD preferred) in Electrical/Electronic Engineering or related discipline.
- Proven hands-on experience in:
- Planar transformer design and layout using PCB-based windings.
- SiC and GaN power device implementation in real-world power converter designs.
- High-voltage LLC resonant converter topologies.
- High-frequency gate drive circuits and power stage integration.
- Strong analytical and simulation skills using tools such as LTspice, PLECS, Altium, ANSYS, or equivalent.
- Experience with lab equipment and test procedures for high-voltage power electronics.
- Ability to work independently and contribute to a collaborative engineering environment.
Desirable:
- Knowledge of EMI/EMC mitigation techniques in power converters.
- Experience in thermal modelling and magnetic material characterisation.
- Familiarity with digital control of power converters (e.g., using DSP or MCU platforms).
What We Offer:
- A chance to work at the forefront of power electronics innovation.
- Flexible and dynamic working environment in the heart of Cambridge.
- Competitive salary and benefits package.
- Opportunities for technical and professional growth.
