Job Description

Senior Power Electronics Engineer – High-Voltage DC/DC Converter Design

The Role

We're looking for a Senior Power Electronics Engineer to lead the design and development of low-power, high-voltage DC/DC converters. This is a hands-on design role covering the full development lifecycle — from topology selection and simulation through to prototyping, test, and release to production. You'll work on compact, high-reliability power solutions where creepage, clearance, isolation, and efficiency at light load are everyday challenges rather than edge cases.

Key Responsibilities

You'll own converter designs end-to-end: selecting and optimising topologies (flyback, resonant, LLC, push-pull or similar) for high-voltage, low-power applications; designing and specifying magnetics, including HV transformer design with attention to insulation systems and parasitics; performing analogue circuit design, control loop compensation, and worst-case analysis; running simulations (SPICE, PLECS or equivalent) to validate designs before hardware; conducting lab bring-up, debug, and characterisation of prototypes; supporting EMC compliance and safety standards work (e.g. IEC 62368, IEC 60601, or sector-specific equivalents); and mentoring junior engineers while contributing to design reviews and best practice across the team.

What We're Looking For

• Degree in Electrical/Electronic Engineering (or equivalent experience), with 7+ years in power electronics design
• Proven track record designing DC/DC converters at high voltage (hundreds of volts to multi-kV output) and low power.
• Strong grasp of HV design fundamentals: creepage/clearance, partial discharge, insulation coordination, corona effects
• Hands-on magnetics design experience, particularly HV transformers
• Confident in the lab: oscilloscopes, HV probes, network analysers, safe HV working practices
• Solid analogue and control theory foundation; comfortable with both analogue and digitally controlled converters
• Familiarity with wide-bandgap devices (SiC/GaN) advantageous

What's on Offer

• Competitive salary of £60k to £65k plus bonus/benefits
• Genuine technical ownership on challenging, niche HV design problems
• Career progression toward Principal/Staff Engineer or technical leadership
