Location:

London, UK

Employment Type:

Full-time, Permanent

About the Role:

We are seeking an experienced Senior Power Supply Design Engineer to join our client, a London-based R&D company that develops high-voltage DC/DC and AC/DC converters for demanding industrial and technology applications. The successful candidate will play a key role in the design, development, and validation of switch-mode power supplies (SMPS), from concept through to production.

As an experienced Senior Power Supply Design Engineer, you will work closely with a cross-functional engineering team covering electrical, mechanical, and manufacturing disciplines to deliver innovative, reliable, and efficient power conversion solutions.

Key Responsibilities:

* Lead the design and development of isolated and non-isolated DC/DC and AC/DC converters, including topologies such as LLC, Flyback, Forward, Half-Bridge, and Full-Bridge.

* Perform detailed circuit design, simulation, and analysis for power stages, control loops, and protection circuitry.

* Carry out component selection (magnetics, semiconductors, capacitors, etc.) to optimise performance, reliability, and cost.

* Support the development of schematics, PCB layouts, and EMI/thermal design considerations.

* Conduct design validation, testing, and troubleshooting of prototype and production units.

* Collaborate with manufacturing and test teams to ensure DFM/DFT compliance and robust volume production.

* Generate and maintain technical documentation, including design reports, test plans, and user manuals.

* Provide mentorship and technical guidance to junior engineers within the team.

Requirements:

* Degree (BEng/MEng) in Electrical or Electronic Engineering (or equivalent).

* 7+ years of experience in switch-mode power supply design (SMPS).

* Proven track record in designing DC/DC and AC/DC converters in the 100 W – 5 kW range (or higher).

* Strong understanding of control theory, magnetics, EMC/EMI compliance, and thermal design.

* Experience with SPICE-based simulation tools and design for safety standards (EN/UL/IEC).

* Familiarity with SiC or GaN devices is advantageous.

* Excellent problem-solving, communication, and documentation skills.

Why Join:

* Work on next-generation high-efficiency power conversion technologies.

* Join a collaborative, technically-driven environment that values innovation.

* Competitive salary, bonus scheme, and professional development opportunities.
