We are seeking an Electrical Engineer to join our engineering team in Madrid, Spain.

Main responsibilities:

• Design and develop EWIS including wire harnesses, cable assemblies, and connector systems compliant with DO-160, SAE AS50881, MIL-DTL-38999, and FAA AC 21-99(0).
• Perform wire gauge calculations, voltage drop analysis, and current capacity assessments. Select materials, connectors, terminals, and protective components based on environmental and performance requirements.
• Develop grounding/bonding schemes for electrical safety and EMC compliance.
• Create harness assembly drawings, wire lists, installation procedures, tooling requirements, and manufacturing documentation.
• Coordinate wire routing through bulkheads, fairings, and structural members, ensuring proper support, strain relief, bend radius, clearances, and protection from chafing, vibration, and environmental hazards.
• Support prototype builds and production installations with hands-on guidance; verify proper EWIS component installation.
• Develop and execute test plans for continuity, insulation resistance, and functional testing; perform acceptance testing, quality inspections, and fault isolation.
• Create and maintain technical documentation including wiring diagrams, ICDs, installation manuals, work instructions, QC procedures, and parts lists.
• Coordinate with manufacturing, quality teams, and suppliers to optimize harness producibility, reduce assembly time, and support procurement.
