Sr. Wiring Harness Quality Technician (Contract)

Harbinger Motors is seeking a highly skilled Sr. Wiring Harness Quality Technician to support the assembly and quality auditing of prototype Low Voltage (LV) and High Voltage (HV) wire harnesses. This is a contract-to-hire position requiring on-site attendance five days a week at our Garden Grove facility. This role is critical in ensuring our prototype vehicles meet the highest standards of electrical safety and performance.

Responsibilities

Assembly & Integration: Build, install, and repair complex LV and HV harnesses according to detailed technical drawings & schematics; Quality Auditing: Perform 100% visual and mechanical inspections on in-house builds, focusing on routing, labeling, tie-wrap tension, and overall workmanship; Verification & Testing: Conduct crimp height analysis, pull-tests, and terminal seating audits to ensure electrical and mechanical integrity; Precision Measurement: Use calipers & tape measures to verify harness lengths and breakout points against engineering specifications; Documentation: Maintain rigorous audit logs and "redline" engineering drawings when discrepancies or design improvements are identified; Precision Soldering: Utilize microscopes to solder components onto PCBAs and perform wire-to-board terminations; Continuous Improvement: Partner with the engineering and production teams to perform root-cause analysis on defects and suggest process optimizations; Lab Stewardship: Maintain a clean, organized, and safe laboratory environment (5S)

Requirements

5+ years of experience building complex wire harnesses from scratch; Mastery of industry-standard crimping, terminating, splicing, and shielding techniques; Proven experience soldering components onto PCBAs under a microscope; Advanced ability to interpret complex wiring diagrams, electrical schematics, and mechanical assembly drawings; Ability to multi-task and pivot quickly in a fast-paced prototype environment; High school diploma or equivalent

Nice to have

Technical trade school certification; IPC/WHMA-A-620 certification; Familiarity with J-STD-001; Knowledge of high-voltage safety protocols and orange-cable handling/shielding; Experience with 5S, Six Sigma, or similar quality management frameworks

Benefits
