Job summary

X4 Technology in Shropshire is seeking a Senior HV Design Engineer to lead hands-on power electronics design from initial requirements through prototype, testing and through to production. You will own the design process across schematics, transformer/magnetics and gate drives, with strong autonomy to influence technical decisions.

Ideal candidates have SMPS/DC‑DC experience, high‑voltage exposure, and proficiency with Altium.

Qualifications

• Experience in switch‑mode power supplies (SMPS) and DC/DC converters.
• Experience with isolated topologies such as resonant/LLC, flyback, forward and full‑bridge.
• Knowledge of MOSFET/IGBT power stages and gate drives; analogue and digital electronics.
• Proficiency with Altium for schematic and PCB design; embedded/microcontroller experience is a bonus.

Responsibilities

• Own the design process from initial requirements through prototype, testing and production.
• Design schematic and select components; transformer and magnetics design.
• Take products through to production and support from concept to qualification.

Job description

I’m currently recruiting for a Senior HV Design Engineer to join an established, high-reliability engineering business based in Shropshire.

This is a genuinely hands‑on power electronics design role — ideal for an engineer who enjoys taking a product from an initial requirement all the way through to prototype, testing and production. There is an opportunity to transition

You’ll have the autonomy to make technical decisions and work across the full design lifecycle, including:

• Schematic design & component selection
• Transformer and magnetics design
• Supporting products through to production

What are they looking for?

Ideally, you’ll have strong experience in:

• Switch‑mode power supplies (SMPS) and DC/DC converters
• Isolated topologies — resonant/LLC, flyback, forward & full‑bridge
• MOSFET/IGBT power stages and gate drives
• Analogue and digital electronics
• Professional schematic/PCB design packages such as Altium
• Microcontroller/embedded systems experience is a bonus

Direct high‑voltage experience would be great, but isn't essential if you have strong, transferable power electronics/SMPS design experience.

Experience within defence, aerospace, nuclear, medical, automotive or other high‑reliability environments would also be highly relevant.

What's on offer?

Shropshire (2 days per week working from home)

If you're an experienced power electronics engineer looking for a role where you can own the design process and work on technically challenging, high‑reliability products, I'd be keen to speak with you.
