• Verify compliance with design specifications, engineering standards, and quality requirements.
• Support development and implementation of inspection and test plans (ITP), checklists, and quality documentation.
• Participate in design reviews to ensure manufacturability, reliability, and compliance with quality standards.
• Support validation of mechanical system performance (e.g., cooling systems, piping, fuel systems, structural elements).
• Identify potential quality risks in design and recommend mitigation actions.
• Support supplier quality control activities, including inspections, audits, and quality checks of mechanical components and systems.
• Monitor manufacturing quality at suppliers and contract manufacturers, including module packagers in North America.
• Verify material quality, fabrication accuracy, and assembly processes against specifications.
• Coordinate with Japan-based teams to ensure alignment with MHI global QA/QC standards.
• Support field quality support activities during installation, commissioning, and site acceptance testing.
• Conduct site inspections and verify installation quality and system performance.
• Assist in identifying and resolving field quality issues in coordination with engineering and project teams.
• Support non-conformance & root cause analysis, including identification, documentation, and tracking of non-conformance issues (NCRs).
• Follow up on corrective actions to ensure proper resolution and prevention of recurrence.
• Ensure QA/QC activities are executed in compliance with Mitsubishi Heavy Industries, Ltd. QA/QC processes, procedures, and documentation standards.
• Support compliance with North American regulatory and certification requirements (e.g., UL, ETL, NRTL, and applicable codes).
• Maintain accurate and complete quality documentation, inspection records, and reports.
• Work closely with design engineering, program management, procurement, and manufacturing teams to resolve quality issues.
• Communicate quality findings, risks, and status clearly to internal stakeholders.
• Support continuous improvement activities across projects and suppliers.
