Job description

Based at our Hethel Perfomance Hub facility in Norfolk, we are looking for a Prototype Vehicle & Test Technician to build, commission, maintain and support prototype and development electric vehicles at MOTV’s development and engineering centre in Hethel, Norfolk, supporting engineering test programmes at Hethel and at test sites across the UK and abroad.

Working side by side with design and engineering, you will be accountable for the quality and readiness of every development vehicle you touch, from first build through HV commissioning and instrumentation to rapid turnaround between test runs. You will work safely to HV safe systems of work and protect the confidentiality of our prototypes.

This is an exciting opportunity to get hands‑on with cutting‑edge electric vehicles from the earliest build stage, often before full documentation exists, and to see your work tested on the rig, track and road at proving grounds and test facilities in the UK and overseas.

Key Responsibilities

• Prototype vehicle build and maintenance
• Build and maintain prototype and development vehicles, systems and sub-assemblies from drawings, BOMs, CAD data and build instructions, often before full documentation exists.
• Install, commission and decommission HV systems: battery packs, e‑drive units, inverters, HV harnesses and charging hardware.
• Record build issues, fitment problems and deviations. Feed them back to design and engineering, and help develop fixes.
• Make and modify parts where needed.

Test support

• Prepare vehicles for test, including fitting instrumentation, data loggers, sensors and test harnesses, and setting up calibration and diagnostic tools.
• Change parts and specifications between test runs, and turn vehicles around quickly after faults.
• Carry out HV diagnostics, isolation and fault‑finding on development vehicles, working to your HV authorisation level.
• Support rig, dyno, track and road testing, and report observations and faults to engineers.

Off‑site testing

• Travel with vehicles to test sites in the UK and abroad, such as proving grounds, tracks, climate testing and partner facilities. This may include overnight stays and weekend work.
• Act as the on‑site technician: set up the temporary workshop, do daily vehicle checks and fix problems at the roadside or trackside.
• Arrange vehicle transport, spares kits, tooling and safe HV transport and storage.

Workshop, safety and compliance

• Follow HV safe systems of work, including isolation and lock‑off, PPE, insulated tooling and damaged battery procedures.
• Keep build records, test vehicle logs, parts usage and condition reports up to date.
• Protect prototype confidentiality.

Essential

• Level 3 Light Vehicle qualification (or equivalent), with OEM, prototype, motorsport or specialist vehicle experience.
• HV qualification: IMI TechSafe Level 3 minimum, Level 4 preferred for live working and HV component repair.
• Proven experience of prototype or development vehicle builds and engineering test support.
• Experience of off‑site testing and working away.
• Strong electrical diagnostics, including reading wiring diagrams, CAN and laptop‑based tools.
• Full UK driving licence, a valid passport, and willingness to travel.

Desirable

• IMI Level 4 HV, or a supervisory or HV Authorised Person role.
• Experience with data acquisition and instrumentation, such as Vector or DEWESoft‑type tools.
• Experience on low‑volume, premium luxury, restomod or bespoke vehicle programmes.
• Motorsport or track operations experience, and a track licence.
• Fabrication skills (TIG/MIG welding, machining).
• Towing licence.

What's On Offer

• Competitive salary, dependent on experience
• Pension
• Life assurance
• Group benefits package, including private medical insurance
• 25 days' annual leave plus bank holidays
