Core Responsibilities

Primary Functions

Perform comprehensive visual and dimensional inspections of highly complex wire harnesses, cable assemblies, and electromechanical systems at various stages of production.
Meticulously verify that all assemblies conform to engineering drawings, schematics, work orders, bills of material (BOMs), and customer-specific requirements.
Utilize a wide range of precision measuring instruments, including calipers, micrometers, pin gauges, and optical comparators, to validate physical dimensions and tolerances.
Conduct a full suite of electrical tests, such as continuity, insulation resistance, and dielectric withstanding voltage (Hipot), using both automated and manual test equipment.
Scrutinize solder joints and crimp terminations to ensure full compliance with rigorous industry standards like IPC/WHMA-A-620 and J-STD-001.
Accurately document all inspection results, non-conformances, and rework requirements within the company's Quality Management System (QMS) or ERP software.
Generate, review, and maintain detailed and accurate inspection records, first article inspection reports (FAIR), and data logs to ensure full product traceability.
Clearly identify, tag, and segregate defective or non-conforming components and assemblies to prevent their unintended use and facilitate disposition.
Collaborate proactively with manufacturing, purchasing, and engineering teams to investigate, troubleshoot, and resolve complex quality issues in a timely manner.
Execute and document First Article Inspections (FAIs) for new product introductions or process changes, providing clear and constructive feedback to the production team.
Routinely verify that all hand tools, crimpers, and test equipment are properly calibrated, identified, and maintained according to established schedules.
Read and interpret complex technical documentation, including multi-level assembly instructions, process specifications, and quality control plans.
Systematically verify part numbers, wire colors and gauges, connector types, backshells, and hardware against the official bill of materials before and during assembly.
Conduct critical in-process inspections at key manufacturing steps to provide real-time feedback and prevent the recurrence of defects downstream.
Perform the final inspection and acceptance testing of finished products, ensuring they are 100% compliant with all quality standards prior to packaging and shipment.
Actively participate in root cause analysis (RCA) and corrective action (CAPA) activities for recurring defects, suggesting robust and sustainable solutions.
Assist in the training and certification of assembly technicians on critical quality standards, visual acceptance criteria, and proper handling techniques.
Diligently uphold and enforce all safety protocols and electrostatic discharge (ESD) prevention procedures within the manufacturing and inspection areas.
Serve as a technical point of contact and interface with customer source inspectors during on-site product acceptance reviews and audits.
Contribute to the organization's continuous improvement initiatives by identifying opportunities to enhance process efficiency, reduce waste, and improve product quality.
Review and approve completed manufacturing travelers and associated paperwork, ensuring all required steps, signatures, and data are present and accurate.
Manage the non-conforming material report (NCMR) process from initiation through to the final disposition and closure of the report.

Secondary Functions

Support engineering and production teams by providing detailed feedback on the manufacturability and testability of new designs.
Participate actively in continuous improvement (Kaizen) events and process optimization workshops aimed at enhancing quality and productivity.
Assist in maintaining the calibration schedule and records for all inspection tools, gauges, and test equipment within the department.
Contribute to the development, review, and refinement of inspection procedures, work instructions, and visual standards.
