Wire Harness Design Engineer (ewis)

Saronic Saronic · Defense · Austin, TX · Engineering

Electrical Wiring Interconnection System (EWIS) Engineer responsible for creating the interconnect architecture for marine platforms, including schematics, harness assembly drawings, and 3D routing using CAD software. Requires strong understanding of manufacturing practices, electrical systems, and industry standards, with a focus on technical support and troubleshooting during harness construction and integration.

What you'd actually do

  1. Develop and maintain EWIS architectures, schematics, and harness assembly drawings in Zuken E3, ensuring drawings contain all information required for manufacturing and installation.
  2. Use NX computer-aided design (CAD) software to route harnesses in 3D per design and installation standards.
  3. Review and revise EWIS designs to meet project specifications and standards, including EMC/EMI, current-carrying capacity, voltage drop, and environmental/classification requirements.
  4. Maintain up-to-date knowledge of industry and military standards such as IPC/WHMA-A-620, ABYC, ABS, and applicable MIL-STDs, and apply them consistently in design and documentation.
  5. Provide technical support and troubleshooting during the construction of a harness, factory test, and integration into the vessel; lead root-cause analysis and corrective actions for nonconformances.
