Job description

The Quality Assurance Manager leads plant-wide quality for a precision cooling equipment manufacturing operation. This role owns the ISO 9001:2015 Quality Management System and drives a prevention-first, data-driven quality culture — shifting the focus from detecting defects to designing and building quality into products and processes. Working with production, engineering, purchasing, and suppliers, the Quality Assurance Manager uses continuous improvement methods, statistical tools, and digital quality systems to reduce cost of poor quality and deliver measurable improvements in product quality, customer satisfaction, and factory performance. Duties are performed personally or through subordinate supervisors and quality staff.

Essential Duties and Responsibilities

• Quality Management System — Own, maintain, and continually improve the company’s Quality Management System in conformance with ISO 9001:2015, applying the process approach and risk-based thinking across all plant operations. Lead internal audit programs, management reviews, and certification/surveillance audits.
• Quality Performance & Data — Define, track, and report plant quality KPIs — first-pass yield, scrap and rework, cost of poor quality (COPQ), supplier PPM, warranty and field-failure rates, and on-time CAPA closure. Use data analytics and statistical methods (SPC, capability studies, MSA) to drive decisions and present performance to senior leadership.
• Corrective & Preventive Action — Lead structured root-cause analysis and corrective action (8D, A3, 5-Why, fishbone) for internal nonconformances, customer complaints, and field issues. Ensure containment, verification of effectiveness, and read-across to similar products and processes.
• Continuous Improvement — Champion Lean and Six Sigma methods to reduce variation and waste, including kaizen events, layered process audits, error-proofing (poka-yoke), and standard work. Build a proactive, prevention-based quality culture on the factory floor.
• Supplier Quality — Manage supplier quality performance: qualification and audits, PPAP/first-article approvals, incoming inspection strategy, supplier corrective action requests (SCARs), and supplier scorecards. Partner with purchasing and engineering on supplier selection and development.
• New Product Introduction — Represent quality in design and development, applying advanced quality planning (APQP-style) tools — design reviews, PFMEA, control plans, and inspection planning — so quality is designed in before launch.
• Regulatory & Product Compliance — Ensure products and processes meet applicable product safety and regulatory requirements (e.g., UL/ETL listings, applicable codes and customer specifications), supporting third-party inspections and maintaining associated documentation.
• Inspection, Test & Calibration — Oversee in-process and final inspection and test operations, nonconforming material control (MRB), and the calibration program for measurement and test equipment, including measurement system analysis.
• Customer Focus — Serve as the plant’s voice of the customer: manage customer complaints, returns, and audits; drive resolution and communicate transparently with customers on quality issues and improvement actions.
• Digital Quality — Advance the use of digital tools (eQMS, ERP quality modules, statistical and BI software) to automate quality records, traceability, and reporting.
• Leadership & Development — Lead, coach, and develop the Quality Assurance team (quality engineers, technicians, and inspectors). Set objectives, manage performance, and build quality competency across production through training and certification programs.
• Cross-Functional Collaboration — Partner with engineering, production, purchasing, and service teams to solve technical problems, improve manufacturability, and align quality objectives with business goals. Prepare and manage the department budget.
• Safety — Support a safe working environment and compliance with OSHA requirements within quality operations.
