Senior / Principal Power Supply Design Engineer
South UK – Permanent
An exciting opportunity has become available for a
Senior / Principal Power Supply Design Engineer
to join a leading technology company in the South of the UK. You will be responsible for the design and development of advanced
DC/DC
and
AC/DC
power conversion solutions for a range of high-performance applications.
As a
Senior / Principal Power Supply Design Engineer
, you will take technical ownership of complex projects from concept through to production, contributing to architecture definition, detailed design, verification, and support.
Key Responsibilities
* Lead the design and development of isolated and non-isolated
DC/DC
and
AC/DC
power supplies, including high-efficiency switch-mode converters.
* Define power architectures and topologies (e.g., flyback, forward, LLC, full bridge, synchronous buck/boost).
* Select key components including magnetics, semiconductors (Si, SiC, GaN), and control ICs.
* Perform hands-on prototyping, simulation, and bench evaluation to validate designs against performance, safety, and compliance requirements.
* Generate technical documentation — schematics, BOMs, design notes, test plans, and compliance records.
* Work closely with cross-functional teams (mechanical, firmware, compliance, manufacturing) to ensure robust, cost-effective designs.
* Provide technical guidance and mentorship to less experienced engineers.
Key Requirements
* Degree (or equivalent) in Electrical/Electronic Engineering or related discipline.
* Strong experience in
power supply design
— both
DC/DC
and
AC/DC
converters.
* Proficiency in magnetics design, control loop stability, and thermal considerations.
* Familiarity with safety and EMC compliance standards (IEC, EN, UL).
* Practical lab experience: oscilloscopes, network analysers, load testing, fault finding.
* (For Principal level) Experience leading projects, mentoring engineers, and making architecture-level decisions.
Desirable
* Experience with wide bandgap semiconductors (SiC, GaN).
* Simulation tools (e.g., LTspice, PLECS, SIMetrix, MATLAB).
* Knowledge of manufacturing processes and DFM.
