Windracers
Windracers develops and operates large autonomous fixed-wing UAVs designed for logistics, humanitarian, and defence applications. Our aircraft combine long-range capability with advanced autonomy to operate efficiently, reliably, and safely. As we expand our programmes and develop next-generation platforms, we are seeking an Electronics CAD Technician / Cable Assembly Draftsman to produce and maintain the electrical, wiring, and cable harness documentation that supports reliable, repeatable manufacture across our fleet.
Role Overview
We are seeking an organised and detail-focused Electronics CAD Technician / Cable Assembly Draftsman to produce accurate electrical design and manufacturing documentation for electronic systems, wiring looms, and cable assemblies.
Working closely with electrical, mechanical, and manufacturing engineers, you will use SolidWorks Electrical to create and maintain electrical schematics, wiring diagrams, cable and harness drawings, connector pinouts, bills of materials, and production drawing packs. Your work will provide the controlled documentation needed to build, inspect, test, and support reliable electrical assemblies.
Key Responsibilities
- Create and maintain electrical schematics, single-line diagrams, wiring diagrams, and interconnection drawings using SolidWorks Electrical.
- Produce detailed cable, wire-harness, and loom assembly drawings, including wire identification, lengths, routing, shielding, breakouts, connector details, and termination requirements.
- Generate and maintain connector pinout schedules, cable schedules, wire lists, from-to lists, and bills of materials.
- Prepare clear manufacturing documentation for cable assembly, inspection, test, and installation activities.
- Develop 2D drawings and support 3D routing or mechanical integration of harnesses where required.
- Select and document suitable wires, cables, connectors, backshells, heat shrink, sleeving, labels, protective coverings, and associated hardware under engineering direction.
- Ensure drawing packs identify applicable part numbers, revisions, materials, standards, tolerances, and assembly notes.
- Maintain accurate CAD libraries for electrical symbols, connectors, manufacturer parts, cable types, and standard components.
- Apply drawing standards, revision control, naming conventions, and document-release processes consistently.
- Review designs for completeness, manufacturability, clarity, and consistency before release.
- Work with production and cable-assembly technicians to resolve drawing queries and incorporate practical feedback into documentation.
- Support prototype builds, fault investigation, design updates, and engineering change requests.
- Liaise with electrical, mechanical, purchasing, quality, and manufacturing teams to ensure documentation supports the complete product lifecycle.
- Maintain configuration-controlled records in the company’s document-management and product-data management systems.
