Job summary

EPC Power Corp. is seeking a Quality Engineer to support the Quality Management System, manufacturing quality, product validation, and reliability initiatives across electromechanical power electronics systems.

You will collaborate with engineering, operations, supply chain, and supplier quality to ensure conformance and readiness for production. The role focuses on continuous improvement, process controls, audits, and data-driven actions to reduce defects and improve yield in energy and grid

Qualifications

• 7+ years of experience in quality engineering within manufacturing environments supporting electromechanical systems, power electronics, or industrial equipment manufacturing.
• Demonstrated experience supporting manufacturing quality, product validation, reliability improvement, and structured problem-solving across the product lifecycle of complex electromechanical assemblies.
• Proven ability to analyze manufacturing performance and key quality indicators such as First Pass Yield, defect rates, rework, and scrap to drive corrective actions and continuous improvement initiatives that improve manufacturing stability and product conformance.

Responsibilities

• Support the implementation and maintenance of the Quality Management System aligned with international quality standards, including maintaining quality procedures, supporting internal and external audits, assisting with Corrective and Preventive Action activities, and contributing to continuous improvement initiatives across manufacturing operations.
• Support quality activities throughout the manufacturing lifecycle of electromechanical assemblies including power conversion systems, inverter cabinets, power electronics modules, control electronics, and integrated electromechanical systems, ensuring manufacturing stability, product conformance, and consistent performance of complex power electronics assemblies used in energy and grid infrastructure applications.
• Implement and maintain process quality controls and control plans to ensure manufacturing stability and product conformance, while monitoring manufacturing process capability and key performance indicators such as First Pass Yield, defect rates, rework, scrap, and production yield to identify opportunities for improvement.
• Support manufacturing process controls to ensure compliance with the Process Audit Standard VDA 6.3 and readiness for internal and external process audits, including participating in process audits, supporting corrective actions related to audit findings, and assisting in evaluating production readiness and process stability.
• Support product validation and verification activities including functional testing, electrical performance verification, environmental testing, and reliability testing, ensuring products meet defined specifications and quality requirements prior to production release.
• Support investigation and resolution of customer quality issues and field failures by participating in structured problem-solving methodologies including Eight Disciplines Problem Solving, A3 Problem Solving Methodology, Root Cause Analysis, and Human Error Root Cause Analysis, while assisting in implementing corrective actions to prevent recurrence.
• Support reliability improvement initiatives for electromechanical products by participating in failure analysis activities related to manufacturing defects or field failures and analyzing reliability and field performance data to identify opportunities for product and process improvements.
• Support continuous improvement initiatives using Lean Manufacturing and Six Sigma methodologies to improve manufacturing quality, production yield, product reliability, and operational efficiency, while monitoring key manufacturing indicators such as First Pass Yield, defect rates, rework, and scrap levels to drive process improvement initiatives.
• Collaborate with engineering teams to support Design for Quality, Design for Manufacturability, and Design for Assembly principles during product development and manufacturing readiness activities.
• Work closely with operations teams to support production quality control and manufacturing process improvements while ensuring quality standards are consistently applied across production processes.
• Partner with the Supplier Quality and Development organization when supplier-related issues impact manufacturing operations.
