The HVAC & Mechanical Commissioning Engineer (Mechanical Dry CSU Engineer) supports planning and field execution of commissioning and startup for HVAC and dry mechanical utility systems at a semiconductor manufacturing facility, including cleanroom and facility HVAC, AHUs, ductwork, process and general exhaust, abatement, chilled water, compressed dry air, bulk gas and vacuum systems. Working within the EPC Commissioning & Startup (CSU) organization, the engineer coordinates with engineering, construction, quality, vendors, subcontractors and customer operations to verify that systems are complete, clean, tested, balanced (TAB and airflow balancing), functionally proven, documented and ready for turnover. The role owns assigned systems from construction completion through functional testing, startup, performance verification, deficiency resolution and final handover. HVAC, mechanical or building commissioning experience from data center, pharmaceutical, healthcare, commercial or industrial projects is welcome.
