• Review drawings, specifications, submittals, and control sequences; identify installation and maintenance concerns.

• Coordinate contractors and internal teams during installation, startup, testing, commissioning, and turnover.

• Evaluate vendor recommendations, verify repair quality, and ensure compliance with safety and technical standards.

Maintenance, Safety, and Operations

• Maintain accurate CMMS work orders, equipment histories, repair records, and corrective-action documentation.

• Follow OSHA, EPA, refrigerant-handling, electrical safety, and Lockout/Tagout (LOTO) requirements.

• Support multiple Texas facilities, shutdowns, production activities, and after-hours HVAC emergencies.

• Communicate equipment conditions, operational risks, and restoration plans to Facilities leadership.

Required Qualifications

• 12+ years of commercial or industrial HVAC experience, or an equivalent combination of education and relevant experience.

• Extensive hands-on experience maintaining, repairing, installing, and commissioning HVAC systems ranging from 5 to 100+ tons.

• Advanced knowledge of refrigeration, airflow, psychrometrics, electrical systems, controls, and HVAC sequences of operation.

• Ability to independently troubleshoot complex mechanical, refrigeration, electrical, and BAS failures.

• Experience with root cause analysis, corrective actions, and industrial, manufacturing, or mission-critical facilities.

• Ability to interpret mechanical drawings, electrical schematics, control diagrams, and equipment specifications.

• Strong communication, documentation, decision-making, and technical leadership skills.

• Willingness to work overtime, weekends, and participate in an after-hours on-call rotation.

Required Certifications

• EPA Section 608 Universal Certification.

Preferred Qualifications

• Experience in aerospace, semiconductor, pharmaceutical, advanced manufacturing, laboratory, or test environments.

• Advanced BAS troubleshooting and programming; experience with Trane, Carrier, Daikin, Johnson Controls, Siemens, Honeywell, or similar platforms.

• Experience with chillers, hydronic and glycol systems, process cooling, dehumidification, humidification, clean rooms, and controlled environments.

• Advanced VFD troubleshooting and experience with compressed air (CDA), vacuum, and process exhaust.

• Experience with commissioning, preventive and predictive maintenance, RCA/RCCA documentation, and contractor oversight.

• Knowledge of equipment redundancy, lifecycle planning, reliability, and critical spare-parts management.

• Plumbing and general mechanical systems experience.

• Ability to operate forklifts, scissor lifts, boom lifts, skid steers, or similar equipment.

• Proficiency with CMMS and digital work-order systems.

Level IV Leadership Expectations

• Own complex HVAC failures through resolution and lead critical troubleshooting efforts.

• Mentor junior technicians and provide technical direction during repairs and commissioning.

• Drive corrective actions, reliability improvements, and equipment replacement recommendations.

• Oversee contractors and OEM service providers while maintaining high standards for safety, quality, and documentation.

• Communicate technical risks and recommendations to Facilities leadership.

Leadership Scope: This is a technical leadership role, not a formal personnel-management position unless additional responsibilities are assigned by Facilities management.

Physical Requirements and PPE

• Stand, walk, bend, kneel, climb ladders, and work on elevated platforms.

• Safely use HVAC tools, diagnostic equipment, meters, and gauges.
