Senior Wire Harness Design Engineer (EWIS)

About the role

Saronic Technologies is seeking a Senior EWIS Engineer to own and drive EWIS architecture execution for a maritime autonomous platform or major subsystem. You will translate schematic intent into manufacturable harness documentation and ensure reliable vessel integration.

Key responsibilities

• Develop and maintain EWIS architectures, schematics, and harness assembly drawings in Zuken E3 with strong configuration control.
• Lead complex 3D harness routing and packaging trade studies using NX (or equivalent), balancing integration constraints and production repeatability.
• Size wiring, shields, and protection devices considering loads, voltage drop, thermal environment, and fault conditions.
• Identify and mitigate EMI/EMC risk through grounding, shielding, routing, and termination strategies.
• Review and approve EWIS designs from junior engineers, mentoring the team and raising documentation quality.
• Serve as primary EWIS interface to manufacturing and external suppliers, driving build readiness and incorporating DFM feedback.
• Plan and review EWIS verification and validation activities, leading root‑cause analysis for wiring and integration issues.
• Interpret and enforce IPC/WHMA, ABYC, ABS, and applicable MIL standards across projects.

Required profile

• Bachelor’s degree in Electrical Engineering, Mechatronics, or a related field.
• 5–12+ years of EWIS, harness engineering, or electrical integration experience with demonstrated ownership.
• Proficiency with Zuken E3 (or equivalent) and 3D harness routing tools such as NX.
• Deep expertise in EWIS integration, production support, and robust grounding/bonding strategies.
• Strong ability to produce and interpret complex technical documentation (schematics, BOMs, harness drawings).
• Proven track record of leading cross‑functional technical execution and mentoring engineers.
• Physical ability to work at a desk for prolonged periods with occasional standing and walking.
