Job Description

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.
