- Ensure all technical designs comply with safety, industry, and regulatory standards (e.g., Chapter 8, TSRGD, DVSA).
- Maintain a structured and accessible database of drawings, BOMs, and technical records for all vehicle builds.
- Review existing builds to identify and implement design improvements and standardisation opportunities.
- Support compliance documentation and product improvement initiatives, refining legacy designs and component selections.
- Assist in the creation of training materials and service documentation to aid ongoing vehicle support and maintenance.
Experience, Qualifications and Skills required:
- Proven experience in vehicle electrical and/or mechanical design, ideally within commercial or specialist vehicle manufacturing.

- Ability to produce and interpret wiring diagrams, hydraulic schematics, and BOMs.
- Strong understanding of vehicle safety standards and regulatory compliance.
- Excellent attention to detail with strong documentation and manual-writing skills.
