Job Summary

The Quality Assurance Manager is responsible for leading and maintaining the Quality Management System (QMS) and ensuring product and process within a precision engineering environment involving CNC machining, fabrication, and tight-tolerance components. This role will drive quality assurance strategies, ensures compliance with ISO 9001 and customer-specific requirements, oversee inspection and metrology systems, and lead continuous improvement initiatives to achieve customer, quality, and operational objectives.

Key Responsibilities

• Lead, maintain and continuously improve the Quality Management System (QMS) in compliance with ISO 9001 and applicable customer-specific requirements.
• Establish and drive quality policies, objectives, and KPIs, and improvement plans aligned with business and production goals.
• Develop, review, and control SOPs, work instructions, control plans, inspection procedures, and quality standards for machining and precision-engineered components.
• Ensure audit readiness and lead internal, external, certification, and customer audits, including timely closure and effectiveness verification of audit findings.
• Interpret engineering drawings, CD&T requirements, specifications, and tight tolerance requirements to ensure accurate appropriate quality and inspection standards are applied.
• Oversee inspection planning and execution for First Article Inspection (FAI), in-process inspection, and final inspection to ensure product conformity.
• Manage the metrology and measurement system, including CMM, vision systems, and conventional measuring equipment such as micrometers, calipers, and height gauges.
• Ensure proper calibration, maintenance, traceability, and capability of inspection and measurement equipment.
• Monitor production quality performance using SPC and other statistical tools, and analyse process capability, including Cp and Cpk, for critical machining processes.
• Drive data-based decision-making through quality dashboards, trend analysis, and regular management reporting.
• Lead investigations into non-conformances, machining defects, process failures, and customer complaints using structured root cause analysis methodologies such as 5Whys and Fishbone Analysis.
• Ensure timely implementation and verification of corrective actions to eliminate recurring quality issues and prevent recurrence.
• Oversee non-conformance management, including containment, disposition, scrap, rework, deviation, and concession control.
• Conduct supplier quality audits, monitor supplier performance, and drive supplier improvement initiatives where required.
• Lead quality risk management activities, including PFMEA and Control Plan development and review for critical processes and products.
• Drive continuous improvement initiatives focusing on yield improvement, scrap, and rework reduction, process capability, and manufacturing process stability using Lean, 5S, Kaizen, and other appropriate methodologies.
• Collaborate closely with Production, Engineering, Planning, and other relevant functions to improve manufacturability, process stability, and overall product quality.
• Lead, mentor, and develop the QA/QC team, including quality inspectors and engineers, ensuring competency in inspection techniques, measurement systems, quality standards, and problem-solving methodologies.
• Act as the primary point of contact for customers on quality-related matters, including customer complaints, audits, quality performance, corrective actions, and technical clarifications.
• Promote a strong quality culture across the organization by ensuring compliance with established procedures and encouraging ownership of quality at every stage of the manufacturing process.

Requirements

• Singaporean Only

Education
