This is an office-based role within a modern, well-equipped facility, offering hands-on technical work and the chance work on a variety of projects.

The Role

You will be heavily involved in the electrical build of prototypes, working with a mix of pre-existing and newly sourced components. Your primary focus will be on wiring, interconnection, and harness creation.

As detailed design drawings are not available, this role suits someone who is self-sufficient, practical, and confident working things out independently, while collaborating closely with the wider engineering team when needed.

Key responsibilities include:

• Electrical build of an industrial prototype
• Designing and assembling wiring harnesses and cable looms
• Sourcing components and connectors as required
• Wiring and interconnecting electrical components
• Documenting wiring harness designs and build processes
• Reworking PCBs, including small surface mount components (desirable)

Skills & Experience Required

• Experience reworking PCBs with small surface mount components
• Proven experience in wiring harness and cable loom manufacturing
• Ability to produce wiring harnesses to a professional standard
• Confidence sourcing electrical components and connectors
• Strong documentation skills for wiring and build processes
• Experience within the medical devices sector (desirable)

Why Apply?

• Work on a cutting-edge industrial product at prototype stage
• Join a small, collaborative project team
• Modern working environment in Warwick
• Competitive salary of £40,000
• Office-based, hands-on technical role with real impact

If you’re an Electronics Technician who enjoys problem-solving, autonomy, and prototype development, this is an excellent opportunity to make your mark.
