Electrical Engineer (EWIS) (m/f/d)

Design and develop electrical wiring interconnection systems for advanced aerospace platforms, ensuring reliable integration, regulatory compliance, and high-performance electrical architectures.

Your Role & Responsibilities

• Design and develop Electrical Wiring Interconnection Systems (EWIS), including wire harnesses, cable assemblies, and connector systems

• Perform wire gauge calculations, voltage drop analysis, and current carrying capacity assessments

• Select suitable wiring materials, connectors, terminals, and protective components based on environmental and operational requirements

• Develop grounding and bonding concepts to ensure electrical safety and EMC compliance

• Create detailed harness assembly drawings, wire lists, manufacturing documentation, and interconnect diagrams (ICDs)

• Develop installation procedures and tooling requirements for harness assembly and aircraft integration

• Ensure proper wire support, strain relief, and protection against vibration, chafing, and environmental influences

• Coordinate wire routing through aircraft structures while maintaining bend radius requirements and installation clearances

• Support prototype builds and production installations with hands-on technical guidance

• Develop and execute EWIS test plans including continuity, insulation resistance, and functional testing activities

• Perform quality inspections, acceptance testing, fault isolation, and troubleshooting of electrical systems

• Ensure compliance with aerospace regulations and standards including DO-160, SAE AS50881, MIL-DTL-38999, and FAA requirements

• Maintain technical documentation including wiring diagrams, installation manuals, parts lists, work instructions, and maintenance documentation

• Collaborate closely with manufacturing, quality, and supplier teams to improve producibility and optimize assembly processes

• Support continuous improvement initiatives across design and production environments
