About the Role

Our products live on scaffolding, in tunnels, on service vehicles and in rain. The electronics have to survive that. As Electronics Hardware Engineer you will own the circuit design of portable lighting products from concept to certification — driver selection and layout, battery pack design, charging behaviour, thermal management and protection against the failures that happen in real use.

You will work inside a small engineering group, with access to test equipment, prototype runs and field feedback. We expect you to question datasheets, test at temperature extremes, and design for repair rather than replacement.

 

Key Responsibilities

• Design LED driver circuits — constant current topologies, dimming, efficiency and EMI behaviour.

• Specify and validate lithium-ion and LiFePO4 battery packs, including BMS requirements, balancing and protection.

• Design charging circuits for 12/24 V vehicle supply, mains and USB-C input.

• Own thermal design for high-power portable lights: heatsink sizing, junction temperature margins, derating curves.

• Prototype, test and document designs; maintain schematics, BOMs and test reports.

• Run EMC pre-compliance testing and fix the issues before formal laboratory testing.

• Support certification work with external labs (CE, EMC, safety, transport of batteries).

• Investigate field failures with after-sales and turn findings into design changes.

 

Requirements

• Degree in electronics, electrical engineering or a related discipline.

• Three or more years designing power electronics or LED lighting hardware in production.

• Solid understanding of switching power supplies, thermal behaviour and battery safety.

• Hands-on with oscilloscopes, power analysers, thermal cameras and bench testing.

• Able to read and write technical documentation in English.

• Experience with Altium, KiCad or an equivalent ECAD tool.

• Practical — willing to take a prototype into a workshop and test it under real conditions.

 

What We Offer

• Salary reviewed twice a year against delivered projects.

• A properly equipped lab bench and access to external test houses.

• Involvement in the full cycle: concept, prototype, certification, field feedback, next generation.

• Small team, short approval chain, real ownership of the products you design.
