Responsibilities:

• UHP Piping & Orbital Welding Verification Inspect and sign off on daily orbital weld coupons, verifying both the initial “in-coupon” and terminal “out-coupon” to ensure weld parameter stability and gas purity.
• Perform 100% visual QA inspection on all “Golden Welds” (final closure/tie-in welds exempt from pressure testing) to guarantee absolute system integrity.
• Conduct QA sampling and audits of all field welds, supplementing the trade contractor’s 100% QC inspection with independent visual checks.
• Verify adherence to ASME B31.3 Chapter X, SEMI F78, and SEMI F81 visual acceptance and alignment criteria for stainless steel tubing.
• Perform final QA verification and sign-off on mechanical and piping installations only after the trade contractor’s QC process is complete and documented.
• Audit trade contractor weld logs, testing records, and quality documentation for accuracy, completeness, and full traceability.
• Witness flange bolt torquing and verify correct gasket materials, bolt grades, lubricants, and torque values against engineering specifications.
• Witness and verify contractor hydrostatic, pneumatic or sensitive leak tests to grant final system acceptance.
• Conduct on-site QA inspections of structural steel pedestals to verify dimensions, squareness/plumbness, weld quality, and coating compliance prior to delivery.
• Perform Special Inspections for tool installations, including the verification of post-installed concrete anchors, adhesive anchors, and seismic restraint brackets.
• Perform final walkdowns on tool exhaust ductwork systems to verify structural integrity, alignment, and proper support.
• Review and validate spark-testing logs and torque logs specifically for Perfluoro polymer-Coated Stainless Steel (PSP) exhaust ductwork to ensure coating continuity and joint integrity.
• Issue and track Owner-level Non-Conformance Reports (NCRs) for any discovered trade deficiencies, and verify the effectiveness of subsequent corrective actions.
• Demonstrated ability to compile comprehensive, audit-ready Quality Turn-Over Packages with zero data gaps prior to turn on of utilities.
• Any other duties or responsibilities that may be assigned to you in your role.

Skills Required:

• A minimum of 2 years of field experience in QA/QC of Mechanical Systems is required.
• Experience in the semiconductor, datacentre or high-tech manufacturing industries are preferred.
• Extensive experience in the implementation of Quality Assurance on large Engineering/Construction Projects.
• Preparation of clear and comprehensive correspondence and reports.
• Strong communication skills required, both verbal and written.
• Good computer skills and familiar with use of Excel, PowerPoint, Word and SharePoint.
• Working knowledge of quality assurance programs and a minimum of 3 years quality assurance auditing /Inspection experience.
