About The Position

Saronic is seeking a Senior EWIS Engineer to own and drive EWIS architecture execution for a platform or major subsystem, translating schematic intent into manufacturable harness documentation and reliable vessel integration. This role leads technical decisions, supports production scale-up, interfaces directly with manufacturing and suppliers, and mentors junior EWIS engineers while ensuring compliance with applicable standards and program requirements.

Requirements

• Bachelor’s degree in Electrical Engineering, Mechatronics, or 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/integration tools (e.g., NX or equivalent).
• 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.

Responsibilities

• 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.
• Plan and review EWIS verification & validation activities; lead root-cause analysis and corrective actions for complex wiring, EMI, and integration issues.
• Interpret and enforce IPC/WHMA, ABYC, ABS, and applicable MIL standards within projects, ensuring consistent application across designs and releases.
