About The Position

The Mechanical Dry Commissioning and Startup (CSU) Engineer supports safe planning and field execution of commissioning and startup activities for dry mechanical utility systems serving a semiconductor manufacturing facility. Systems include cleanroom and facility HVAC, process and general exhaust, compressed dry air, bulk gas, and vacuum systems.

Working for the EPC organization, the engineer coordinates with engineering, procurement, construction, quality, vendors, subcontractors, and customer operations to confirm systems are complete, clean, tested, functionally proven, documented, and ready for turnover and operation. The role owns assigned systems from construction completion through commissioning, startup, performance verification, deficiency resolution, and final handover.

The engineer develops commissioning plans and documentation; verifies construction completion and turnover; leads or supports commissioning, startup, testing, and troubleshooting; coordinates technical problem resolution; maintains quality and handover records; and ensures safety and regulatory requirements are followed. Work takes place in an active construction and commissioning environment, with potential support for shift work, off-hours testing, or schedule-critical startup activities when required.

Requirements

• Bachelor's degree or international equivalent and 2–5 years of relevant experience, or 6–9 years of relevant work experience in lieu of a degree.
• Ability to read and interpret P&IDs, process flow diagrams, ductwork and piping plans, equipment drawings, specifications, sequences of operation, vendor manuals, and system boundary drawings.
• Working knowledge of dry mechanical systems, including air handling and makeup air units, fan filter units, exhaust fans and scrubbers, air compressors and dryers, vacuum pumps, bulk gas distribution, dampers, valves, ductwork, piping, and associated instrumentation.
• Understanding of mechanical completion, turnover, pre-commissioning, commissioning, troubleshooting, and system acceptance workflows.
• Working knowledge of duct leakage testing, pressure and leak testing, purging and blowdown, testing, adjusting, and balancing (TAB), and equipment startup practices.
• Working knowledge of lockout/tagout and hazardous energy control, including commissioning-specific risks involving pressure, rotating equipment, compressed and inert gases, oxygen-deficient atmospheres, and stored energy.
• Ability to evaluate field conditions, organize technical information, identify root causes, and coordinate practical corrective actions across disciplines.
• Ability to produce clear technical procedures, test records, status reports, and turnover documentation using project-approved digital systems.
• Strong written and verbal communication skills and ability to work effectively with craft supervision, engineers, vendors, subcontractors, commissioning teams, and customer representatives.
• Ability to work in an active construction and commissioning environment, including field walkdowns, climbing stairs and ladders, and wearing required personal protective equipment.
• Availability to support shift work, off-hours testing, or schedule-critical startup activities when required by the project.

Nice To Haves

• Experience commissioning cleanroom HVAC, exhaust, or gas and vacuum utility systems in a high-technology manufacturing environment.
• Experience with building automation systems, distributed control systems, commissioning databases, digital turnover platforms, and electronic test documentation.
• Familiarity with integrated system testing and interfaces among mechanical, electrical, instrumentation, controls, HVAC, process utility, and life-safety systems.
• Knowledge of cleanroom classification (ISO 14644), room pressurization, gas purity and moisture specifications, and cleanliness requirements relevant to assigned systems.

Responsibilities

• Develop and maintain commissioning plans, procedures, check sheets, test forms, and turnover requirements for assigned systems.
• Establish system boundaries, turnover sequence, commissioning logic, test prerequisites, and acceptance criteria aligned with the project schedule.
• Review P&IDs, drawings, specifications, sequences of operation, equipment data, and vendor submittals for commissioning readiness.
• Participate in design, constructability, hazard, and operational readiness reviews; identify risks, constraints, vendor support, test equipment, and temporary system needs.
• Coordinate construction-to-commissioning turnover and verify packages are complete and aligned with system boundaries.
• Perform field walkdowns to confirm installation meets approved drawings, specifications, and vendor requirements.
• Validate mechanical completion, testing, cleaning, purging, leak testing, and preservation records.
• Develop, prioritize, track, and close punch-list items.
• Lead or support inspections, valve and damper lineups, equipment rotation checks, purging, blowdowns, pressurization, and energization.
• Coordinate startup and troubleshooting of HVAC equipment, fan filter units, exhaust systems, scrubbers, compressors, dryers, vacuum pumps, valves, dampers, ductwork, and piping.
• Monitor airflow, pressure, temperature, humidity, dew point, and gas purity against acceptance criteria; document results and coordinate corrective actions.
• Support testing, adjusting, and balancing (TAB) and integrated testing with other disciplines.
• Work with engineering to resolve field conditions, design discrepancies, nonconformances, requests for information, and commissioning changes.
• Coordinate OEM and supplier support for installation verification, startup, testing, troubleshooting, and documentation.
• Communicate system status, risks, constraints, and recovery actions.
• Maintain accurate commissioning records and turnover documentation; prepare mechanical completion packages, test records, commissioning reports, and acceptance documentation.
• Confirm redlines, vendor records, spare parts, and O&M documentation are captured.
• Support customer walkdowns, system orientation, operational readiness, and final acceptance; document remaining items with clear ownership and completion criteria.
• Demonstrate visible safety leadership and stop work when conditions are unsafe.
• Perform work in accordance with ES&H, quality, regulatory, and permit requirements.
• Support lockout/tagout, hazardous energy control, line-breaking, compressed and inert gas handling, confined space, oxygen-deficient atmosphere, and stored-energy controls.
• Participate in hazard analyses, pre-task planning, readiness reviews, and pre-startup safety reviews.
• Verify test boundaries, exclusion zones, communications, and restoration requirements before startup.
