Project Overview: Fab 62 is an advanced semiconductor fabrication facility for Intel Corporation, located at Intel's Ocotillo campus in Chandler, Arizona. As part of this work, the M&T team is responsible for delivering the engineering, procurement, and construction scope required to complete and finish-out a leading-edge chipmaking facility - a highly demanding environment where precision, cleanliness, schedule certainty, and coordination across thousands of craft and professional personnel are essential to success. The project supports the continued expansion of domestic semiconductor manufacturing capacity, contributing to a more resilient technology supply chain while creating significant opportunity for the local Arizona workforce. Joining the Fab 62 team means contributing directly to one of the most strategically important construction efforts in the United States and helping deliver the infrastructure behind the next generation of microelectronics. Job Summary: The Mechanical DRY CSU Engineer leads the discipline CSU team responsible for high-purity process and utility systems (specialty gases, chemicals, slurry, ultrapure water, and waste) during commissioning and start-up of the semiconductor fabrication facility. The role plans and supervises discipline execution from construction completion through system turnover to operations, ensuring work is performed safely, on schedule, and to design intent. The Mechanical Dry Commissioning Engineer is responsible for planning, coordinating, and executing dry commissioning activities for mechanical systems within semiconductor fabrication facilities (fabs). The role ensures systems are installed correctly, meet design requirements, operate safely, and are ready for wet commissioning, process qualification, startup, and handover to operations. This position works closely with Engineering, Construction, Vendors, Quality, Facilities, and Operations teams to verify mechanical systems including HVAC, cleanroom systems, process cooling water, chilled water, heating water, exhaust systems, bulk gas infrastructure, and supporting utilities. Owns the planning, supervision, and execution of CSU for high-purity process and utility systems (specialty gases, chemicals, slurry, ultrapure water, and waste) on the F62 project - Mechanical dry commissioning engineering in the semiconductor industry involves pre-functional verification and testing of process mechanical, cleanroom HVAC, and dry utility systems. Accountable for the discipline's safe and quality execution within the CSU plan set by the Commissioning Manager. •
