QA/QC Engineer – Mechanical & Process (HP/UHP Systems)

About the role

We are seeking a QA/QC Engineer specialized in Mechanical & Process to lead quality assurance for high‑purity (HP) and ultra‑high‑purity (UHP) piping systems on a large‑scale advanced manufacturing project. The role combines hands‑on oversight of orbital welding, cleanroom construction, and process piping quality control.

Key responsibilities

• Ensure quality of HP/UHP piping systems including UPW, CDA, nitrogen, specialty gases, and chemical lines.
• Monitor fabrication, erection, and installation activities on‑site.
• Conduct pre‑fabrication audits and verify material traceability (MTC, heat numbers, ASTM compliance).
• Oversee orbital welding operations, including welder/operator qualification, purging/back‑purging protocols, and weld inspection documentation.
• Review and approve ITPs, WPS/PQR, and welding records.
• Witness and validate hydro‑static, pneumatic, and helium leak testing, as well as system flushing and cleanliness checks.
• Enforce cleanroom protocols for contamination control, material handling, and surface protection.
• Manage NCRs, drive root‑cause analysis, and ensure timely closure.
• Coordinate with contractors, consultants, and stakeholders to maintain quality compliance.
• Prepare inspection reports, quality dashboards, and management presentations.
• Support commissioning activities and system handover milestones.

Required profile

• B.E. / B.Tech in Mechanical, Chemical or Process Engineering.
• 8–15 years of QA/QC experience on mechanical or process systems.
• Hands‑on experience with HP/UHP piping (UPW, gases, chemicals).
• Strong knowledge of ASME, SEMI and AWS standards.
• Ability to read and interpret P&IDs, isometric drawings and process layouts.

Required skills

• Orbital welding and GTAW (SS 316L) expertise.
• Purging protocols and oxygen control.
• Cleanroom construction and contamination control practices.
• Material traceability (MTC, heat numbers, ASTM compliance).
• Hydro‑static, pneumatic and helium leak testing.
• System flushing and cleanliness verification.
• Non‑conformance report (NCR) management and root‑cause analysis.
• Reading P&IDs, isometric drawings, and process layouts.
• Familiarity with ASME, SEMI and AWS standards.
