Key Responsibilities and Required Skills for Quality Control Inspector

🎯 Role Definition

A Quality Control (QC) Inspector is a critical team member responsible for safeguarding product integrity and ensuring compliance with all established quality standards and engineering specifications. This role involves conducting detailed inspections at various stages of the production cycle—from incoming raw materials to in-process assemblies and final finished goods. By meticulously measuring, testing, and documenting product characteristics, the QC Inspector identifies and isolates defects, prevents non-conforming products from proceeding, and plays a vital part in the company's continuous improvement efforts. You will be the expert on quality, collaborating closely with production, engineering, and supply chain teams to resolve issues and maintain a culture of excellence on the manufacturing floor.

Core Responsibilities

Primary Functions

Perform comprehensive visual and dimensional inspections of raw materials, in-process components, and finished assemblies to ensure conformance with engineering drawings, specifications, and quality standards.
Utilize a wide range of precision measuring instruments, including calipers, micrometers, height gauges, bore gauges, optical comparators, and Coordinate Measuring Machines (CMM), to verify product dimensions.
Accurately interpret complex engineering blueprints, technical drawings, and geometric dimensioning and tolerancing (GD&T) callouts to confirm product compliance.
Meticulously document inspection results, record test data, and maintain detailed logs of approved and rejected parts in the quality management system (QMS) or ERP system.
Generate, manage, and process Non-Conforming Material Reports (NCMRs) for any parts or products that fail to meet specifications, and segregate non-conforming items to prevent unintended use.
Conduct First Article Inspections (FAIs) on new or revised products, creating detailed reports to validate that production processes are capable of producing parts to specification.
Approve finished products by confirming they meet all quality requirements and release them for shipment; prepare and review Certificates of Conformance (CoC) as required.
Collaborate directly with production supervisors and operators to communicate quality issues, provide feedback, and assist in identifying the root cause of defects.
Calibrate and maintain inspection, measurement, and test equipment, ensuring all tools are in proper working order and their calibration is current.
Perform receiving inspections on materials and components from suppliers to verify they meet purchase order specifications and quality requirements.
Execute in-process quality audits on the production floor to ensure manufacturing processes are being followed correctly and are producing conforming parts.
Participate actively in root cause analysis and corrective/preventive action (CAPA) initiatives to address quality issues and prevent their recurrence.
Review and approve production documentation and work instructions to ensure they contain clear, accurate, and up-to-date quality criteria.
Support the development and refinement of inspection plans, procedures, and quality control checklists to improve the efficiency and effectiveness of the inspection process.
Monitor and analyze production data using Statistical Process Control (SPC) methods to identify trends, process shifts, and opportunities for improvement.

Secondary Functions

Assist in training production personnel on quality awareness, measurement techniques, and the proper handling of conforming and non-conforming materials.
Contribute to continuous improvement and Lean Manufacturing initiatives by identifying and suggesting opportunities to reduce waste, improve quality, and increase efficiency.
Participate in internal and external audits (e.g., ISO 9001, AS9100) by providing documentation, explaining processes, and answering auditor questions.
Support the supplier quality team by providing data and feedback on the performance of externally sourced components and materials.
Maintain a clean, organized, and safe work environment within the quality lab and inspection areas, adhering to all 5S and safety protocols.
