Lead QAQC - Mech & Process (Cleanroom)

Job description

Job ID: 41185 Date: 10 Jul 2026 Location: Dholera, GJ, IN Department: Projects Business: Semifab ## **Responsibilities** Responsible for quality assurance of mechanical piping fabrication and erection, with a specialization in high purity and ultra-high purity (HP/UHP) process systems and cleanroom infrastructure. This is a technically demanding role requiring deep familiarity with semiconductor-grade cleanliness standards, orbital welding, and cleanroom construction protocols. Serves as a critical quality interface with the GC, PMC, and specialist sub-contractors. - Oversee fabrication and installation quality of HP/UHP piping systems – UPW, CDA, N2, specialty gas, and chemical distribution. - Conduct pre-fabrication audits at spool fabrication shops; verify material traceability (heat certificates, mill certs) per ASTM standards. - Monitor orbital welding operations — welder/operator qualifications, purging protocols, borescope weld inspection. - Review and approve ITPs, WPS/PQR, and welding records for SS 316L, PVDF, and other process pipe materials. - Witness hydro/pneumatic pressure tests, helium leak tests, and particle count tests per system flushing protocols. - Enforce cleanroom construction protocols — gowning, contamination control, material handling, and surface protection. - Track NCRs from identification through verified closure; analyse systemic trends. - Coordinate with GC, PMC, process engineers, and move-in teams for CMIA (Construction to Move-In Authorization) milestones. ## **Key Responsibility** - Strong understanding of SEMI, ASME, IS and AWS codes - Familiarity with orbital welding, manual GTAW for fittings, flanges, and repair welds under controlled conditions - Familiarity with Purging and back-purging protocols for stainless steel; oxygen monitoring (<20 ppm) - Experience in weld coupon qualification, tensile, bend, and borescope visual inspection criteria - Familiarity with thermoplastic welding (IR fusion, socket fusion) for PVDF and PP piping systems - Strong coordination skills — experienced in daily interface with GCs, PMC, and third-party inspectors - Ability to prepare professional quality reports and management presentation decks - Proficient in MS Excel (trackers, pivot tables, charts), PowerPoint, and Word - Detail-oriented, assertive in quality enforcement, and composed under schedule pressure. - Drive GCs accountability via clarity, technical credibility, documented evidence, and disciplined escalation—not hierarchy. - Ability to read process flow diagrams, P&IDs, isometric drawings, and cleanroom layout drawings - Quick to learn proprietary commissioning and quality management platforms used on the project ## **Qualification** B.E. / B.Tech in Mechanical, Chemical, or Process Engineering ## **Experience** - 10+ years in quality for process/mechanical construction – at least 3 years on HP/UHP or cleanroom projects - Prior involvement in FAB construction projects (e.g., Micron, Intel, GlobalFoundries, Siltronics etc.), pharmaceutical (ISPE/GMP), or advanced electronics facility preferred. - Experience with high-purity piping, gas distribution systems, and vibration-sensitive installations ## **Competencies** A. Customer Empathy A. Agility A. Teamwork A. Future Ready A. Deep Domain Knowledge A. Pioneering A. Purposeful Pursuit of Goals
