Lead HVAC/Cleanroom CSU Engineer (Field)

Bechtel Corporation•Town of Clay, NY

6d•$105,000 - $160,200

About The Position

The Lead HVAC/Cleanroom Commissioning and Start-Up (CSU) Engineer leads commissioning and startup activities for HVAC and cleanroom environmental systems on semiconductor projects. The role ensures air handling, filtration, pressurization, and thermal control systems are installed, tested, commissioned, and turned over to support tool installation and production ramp-up. Accountability spans system definition through turnover, including make-up air units, recirculation air units, fan filter units, air handling units, chilled and hot water systems, humidification and dehumidification equipment, exhaust and scrubber systems, and associated control sequences. The engineer verifies that cleanrooms meet design requirements for ISO classification, pressure cascade, temperature, and relative humidity during operation. As the technical lead and primary point of contact for HVAC and cleanroom systems during commissioning, this role directs and mentors commissioning engineers and technicians and coordinates with engineering, construction, QA/QC, vendors, and owner operations teams. The position is based in Clay, New York, with full-time office/project telework designation. National relocation with family is authorized.

Requirements

Bachelor's degree or international equivalent and 8–10 years of relevant experience, or 12–14 years of relevant work experience.
Experience commissioning and starting up HVAC and cleanroom systems in semiconductor, advanced manufacturing, pharmaceutical, or critical-environment facilities.
At least 4 years of relevant experience commissioning HVAC systems, including air handling units, make-up air units, recirculation air units, fan filter units, chillers, boilers, pumps, and exhaust systems.
Working knowledge of cleanroom design and operation, including ISO 14644 classification, pressure cascade, contamination control, and gowning protocols.
Working knowledge of ASHRAE guidelines and standards.
Familiarity with SMACNA duct construction and leakage testing standards.
Knowledge of building management systems/building automation systems (BMS/BAS) and sequences of operation for cleanroom environmental control.
Experience directing testing, adjusting, and balancing (TAB) activities.
Experience in commissioning or technical consulting, including facility design, engineering, construction management, or a related discipline.
Ability to work effectively with multidisciplinary teams.
Ability to manage time and priorities to meet schedule commitments and quality objectives.
Effective communication with engineering, operations, client, and stakeholder teams.

Nice To Haves

NEBB or AABC certification.
Familiarity with semiconductor facility standards and critical environment systems.
Experience using commissioning software such as SmartCompletions and other applicable digital tools.

Responsibilities

Lead commissioning and startup for HVAC and cleanroom environmental systems, including make-up air units, recirculation air units, fan filter units, air handling units, exhaust systems, chilled water systems, hot water systems, and humidification equipment.
Develop commissioning plans, turnover packages, test procedures, checklists, and acceptance criteria for HVAC and cleanroom systems.
Verify cleanroom performance against ISO 14644 classification, pressure cascade, air change rate, temperature, and relative humidity requirements.
Direct testing, adjusting, and balancing (TAB) activities and review TAB reports for compliance with design intent.
Witness and evaluate factory acceptance tests (FATs) and site acceptance tests (SATs) for HVAC equipment and cleanroom systems.
Review mechanical drawings, P&IDs, ductwork layouts, control schematics, sequences of operation, and project specifications.
Perform functional performance testing and integrated systems testing, including failure mode and recovery scenarios affecting cleanroom environmental control.
Coordinate with the controls and automation team to verify BMS/BAS points, alarms, interlocks, and sequences of operation for HVAC and cleanroom systems.
Coordinate with commissioning, design engineering, construction, vendors, and owner representatives to resolve technical issues and maintain project alignment.
Enforce project safety requirements, lockout/tagout procedures, and cleanroom gowning and contamination control protocols throughout commissioning activities.
Lead punch list development, tracking, and closeout for HVAC and cleanroom systems through client turnover.
Supervise, mentor, and develop commissioning engineers and technicians assigned to the HVAC and cleanroom scope.
Review performance curves, metrics, trackers, and user feedback to identify trends and drive continuous improvement.
Define and identify owner goals, operational needs, building performance expectations, and related commissioning responsibilities.
