Wire Harness Design Engineer - EWIS (Associate - Principal)

Saronic Technologies is a leader in revolutionizing autonomy at sea, dedicated to developing state-of-the-art solutions that enhance maritime operations through autonomous and intelligent platforms.

Job Overview

Saronic is seeking a skilled Electrical Wiring Interconnection System Engineer, responsible for creating the interconnect architecture for marine platforms at scale. These designs serve as blueprints for manufacturing of harnesses. The role requires a strong understanding of manufacturing practices of individual harnesses and harness integration, excellent communication with electrical systems and mechanical engineers, and system schematic creation and change management. EWIS Engineers must also possess strong attention to detail, problem-solving skills, and the ability to work collaboratively with other team members to ensure that projects are completed efficiently and accurately.

Responsibilities & Duties

• Develop and maintain EWIS architectures, schematics, and harness assembly drawings in Zuken E3, ensuring drawings contain all information required for manufacturing and installation.

• Use NX computer-aided design (CAD) software to route harnesses in 3D per design and installation standards.

• Review and revise EWIS designs to meet project specifications and standards, including EMC/EMI, current-carrying capacity, voltage drop, and environmental/classification requirements.

• 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.

• 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.

• Plan and support verification and validation activities (continuity/insulation resistance, hipot, and harness test board checks) and document results for compliance and quality audits.

• Communicate effectively with project managers, suppliers, and production stakeholders to coordinate build readiness, design-for-manufacture feedback, and schedule/risk mitigation.

Qualifications & Skills

• Bachelor’s degree in Electrical Engineering, Mechatronics, or related field.

• 5–10+ years of experience in EWIS design, harness engineering, or electrical integration within automotive, marine, or aerospace industries.

• Proficiency in Zuken E3, Siemens Capital, or equivalent electrical design tools.

• Experience using NX, CATIA, or SolidWorks Electrical for 3D harness routing and integration.

• Strong understanding of electrical systems design principles, grounding/shielding practices, and connector standards.

• Demonstrated ability to interpret and produce complex technical documentation, including schematics, BOMs, and installation drawings.

• Deep familiarity with industry standards such as IPC/WHMA-A-620, ABYC, and ABS.

• Proven ability to manage multiple projects and priorities in a fast-paced environment.

Physical Requirements

• Prolonged periods of sitting at a desk and working on a computer.
