High Purity Welding Jobs (NOW HIRING)

Overview

The QA/QC Engineer will be responsible for developing, implementing, and managing quality assurance and quality control programs for the construction of Chemical Distribution System (CDS), gas cabinets, and associated high-purity piping used in a high-volume semiconductor manufacturing facility. The primary goal is to ensure the purity, integrity, and reliable operation of the chemical and gas infrastructure to prevent contamination and maintain high product yield.

Key Responsibilities

1. Quality Assurance (QA) and Documentation

• Develop, revise, and maintain the Quality Management System (QMS) documents specific to CDS, including Standard Operating Procedures (SOPs), Work Instructions (WIs), and Quality Checklists.
• Ensure all installation, testing, and commissioning activities for CDS and piping comply with industry standards (e.g., SEMI, ASTM), client specifications, and local regulations.
• Manage the Material Traceability program, ensuring all components (valves, pipes, fittings, filters, pumps) used are correctly certified and traceable to their manufacturer and purity specifications.
• Conduct internal and external audits of contractors and vendors to verify adherence to quality standards and specifications.

2. Quality Control (QC) and Testing

• Oversee and perform critical QC inspections during all phases of CDS installation, including:
  • Orbital Welding inspection and certification (review of weld logs and NDT reports).
  • Dimensional checks of piping systems and equipment layout.
  • Cleanroom protocol adherence during installation.
• Manage and witness specialized testing for high-purity systems:
  • Pressure Testing (hydrostatic/pneumatic).
  • Helium Leak Testing to ensure system integrity.
  • Particle Count Testing (e.g., using a non-volatile residue (NVR) test or particle counter) of wetted surfaces to confirm cleanliness .
  • Oxygen and Moisture Analysis of inert gas lines.
• Review and approve Final Turnover Packages (TOP), including all QC reports, test results, certifications, and as-built drawings, prior to system release.

3. Non-Conformance Management & Continuous Improvement

• Identify, document, and track all quality non-conformances (NCRs) and material rejections.
• Lead Root Cause Analysis (RCA) for quality failures or deviations in the CDS.
• Implement effective Corrective and Preventive Actions (CAPA) to prevent recurrence.
• Drive continuous improvement initiatives to enhance the quality and efficiency of CDS installation and maintenance processes.

Required Qualifications

• Education: Bachelor's degree in Chemical Engineering, Mechanical Engineering, Materials Science, or a related field.
• Experience: Minimum 3-5 years of experience in QA/QC, specifically within high-purity process piping, chemical delivery systems, or similar infrastructure in the semiconductor, pharmaceutical, or ultra-clean manufacturing industries.
• Technical Skills:
  • Strong knowledge of SEMI standards related to chemical and gas delivery (e.g., SEMI F1, F5, F57).
  • Proficiency in interpreting technical drawings, P&IDs (Piping and Instrumentation Diagrams), and material specifications.
  • Experience with orbital welding quality requirements and inspection.
  • Familiarity with various QC testing methods for clean systems (pressure decay, helium leak, particle counting).
• Certifications (Preferred): ASQ Certification (e.g., CQE), Welding Inspector Certification (e.g., AWS CWI).

Key Attributes

• High Attention to Detail: Critical for identifying minute defects in high-purity components.
• Excellent Communication: Ability to clearly communicate quality requirements and non-conformance issues to engineers, contractors, and management.
• Safety Conscious: Deep commitment to safety protocols, especially when working with hazardous production materials (HPMs).
