Interface, Inc. is seeking a Customer Quality Engineer to serve as a key technical liaison between our customers and internal Manufacturing, Engineering, Calibration, Sales, and Quality teams. This position is responsible for leading customer quality investigations from initial complaint through final resolution, including product evaluation, root cause analysis, corrective action, and effectiveness verification. The Engineer will use technical data and structured problem-solving methods to identify causes of product or process issues, communicate clear and accurate findings to customers, and drive improvements in product reliability, manufacturing processes, and Interface's QMS.

The ideal candidate is a hands-on problem solver with strong technical communication skills and experience investigating quality issues in a precision manufacturing, measurement, calibration, or instrumentation environment.

• Coordinate containment activities for affected finished goods, work-in-process, inventory, and, when applicable, products already shipped to customers.
• Plan and coordinate returned-product evaluations, functional testing, calibration reviews, manufacturing record reviews, and technical data analysis.
• Perform structured root cause analysis using tools such as 8D, 5 Whys, cause-and-effect analysis, and fault tree analysis.
• Determine both the cause of the issue and why existing processes or controls did not prevent or detect the condition.
• Partner with Manufacturing, Engineering, Calibration, and other process owners to develop and implement appropriate corrective and preventive actions.
• Track corrective actions through completion, identify and elevate barriers, and verify effectiveness through testing, audits, data analysis, or recurrence monitoring.

• Use complaint and quality data to identify opportunities for improvements to manufacturing processes, inspection methods, control plans, procedures, training, and risk assessments.
• Support internal audits, systemic corrective actions, and continuous improvement initiatives.
• Provide guidance to cross-functional teams on evidence collection, root cause analysis, structured problem solving, and corrective action methodology.

• Bachelor's degree in Engineering, Quality, Manufacturing, or a related technical discipline; equivalent combinations of education and relevant experience may be considered.
• Ability to read and interpret engineering drawings, technical specifications, calibration results, inspection records, and test data.
• Experience investigating customer complaints, product failures, manufacturing nonconformities, or similar technical quality issues.
• Working knowledge of Quality Management System principles, including complaint handling, nonconforming product control, document control, and corrective action.
