Reading, Reading, United Kingdom Ampere Recruitment Full time £60,000 - £120,000 per year

Power Supply Design Engineer

Location:
Berkshire

Represented by:
Ampere Recruitment

Overview

Ampere Recruitment is supporting a leading technology innovator in the search for a skilled
Power Supply Design Engineer
. The successful candidate will design and develop advanced switch-mode power supplies used across industrial and medical applications.

This role involves hands-on design of
DC/DC
and
AC/DC
converters using a wide range of modern topologies — including LLC, Flyback, Forward, Full-Bridge, Half-Bridge, and Resonant converters.

Key Responsibilities

Power Electronics Design

  • Design, simulate, and validate
    DC/DC
    and
    AC/DC
    SMPS architectures from concept through to production.
  • Select and implement appropriate topologies (LLC resonant, Phase-Shifted Full Bridge, Flyback, Forward, Buck/Boost, etc.).
  • Develop high-efficiency power stages using Si, SiC, and GaN devices.
  • Create and optimise magnetics (transformers & inductors) for resonant and hard-switched designs.
  • Perform simulation and modelling using tools such as LTspice, PLECS, or similar.

Prototyping & Verification

  • Build and test prototype circuits, evaluating thermal performance, efficiency, EMI/EMC behaviour, and reliability.
  • Conduct design validation, fault analysis, and root-cause investigations.
  • Support compliance testing (EN/UL standards, safety, EMC, isolation).

Product Development & Documentation

  • Generate schematics, BOMs, test plans, design reports, and manufacturing documentation.
  • Collaborate closely with mechanical, firmware, and manufacturing teams to ensure smooth product integration.
  • Support transition from prototype to mass production, ensuring design for manufacturability (DFM) and design for reliability (DFR).

Required Experience

  • 3–10+ years' experience in
    switch-mode power supply (SMPS) design
    .
  • Strong understanding of power converter topologies (LLC, resonant converters, Flyback, Forward, Full Bridge, Half Bridge, PFC stages, etc.).
  • Hands-on experience designing both
    AC/DC
    (up to 1kW+ ideal) and
    DC/DC
    converters.
  • Ability to design magnetics or work closely with magnetics suppliers.
  • Proficient with simulation tools (LTspice, PLECS, PSIM, or equivalent).
  • Knowledge of safety standards, EMC considerations, thermal management, and PCB layout best practices for high-density supplies.

Preferred (Not Essential)

  • Medical , industrial , or automotive design standards
  • Familiarity with digital control (DSP/MCU-based power supplies)

What This Role Offers

  • The chance to work on cutting-edge power electronics technologies
  • Influence over topology selection and product architecture
  • Exposure to advanced magnetics, resonant technologies, and high-efficiency platforms.

If this role sounds of interest, then please apply with an up-to-date CV and contact information.
