Responsibilities & Requirements

• Develop and maintain EWIS architectures, schematics, and harness assembly drawings in Zuken E3 with a strong emphasis on design intent, configuration control, and manufacturability.

• Lead complex 3D harness routing and packaging trade studies using NX (or equivalent), balancing integration constraints, serviceability, and production repeatability.

• Independently size wiring, shields, and protection devices considering continuous/transient loads, voltage drop, derating, thermal environment, and fault conditions.

• Identify and mitigate EMI/EMC risk through grounding/bonding strategy, routing/separation, shielding, and termination choices aligned to system architecture.

• Review and approve EWIS designs produced by Level 1 engineers; mentor and raise documentation and design quality across the team.

• Serve as a primary EWIS interface to manufacturing and external suppliers; drive build readiness, incorporate DFM feedback, and mitigate schedule/technical risk.

• Deep expertise in EWIS integration and production support, including independent wire/shield/protection sizing and robust grounding/bonding/shielding strategies.

• Strong ability to interpret and produce complex technical documentation (schematics, BOMs, harness/installation drawings) and ensure design intent carries through to installation.

• Proven ability to lead cross-functional technical execution, improve workflows/documentation quality, and mentor engineers.
