As a Mechanical Quality Assurance Inspector working with the LotusWorks team, you will join our client site in the high-tech semiconductor sector. This job is based in a cutting-edge facility in Manassas, Virginia.

You will act as the Owner’s Representative to verify, audit, and sign off on mechanical, piping, and structural installations after trade contractors have completed their Quality Control (QC) processes. This role ensures that all installations—ranging from ultra-high purity (UHP) process systems to tool structural supports, seismic anchoring, and exhaust ductwork—strictly comply with engineering designs, semiconductor industry codes, and facility standards.

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.
