Senior HVAC Maintenance Technician

Responsibilities

• Lead preventive, predictive, and corrective maintenance across AHUs, chillers, boilers, heat exchangers, VAVs, exhaust systems, dehumidifiers, and split systems—owning temperature, humidity, airflow, and pressurization in GMP spaces.
• Ensure cleanroom compliance with ISO 14644: HEPA integrity, airflow patterns, recovery times, and differential pressures; support aseptic areas and gowning zones.
• Optimize and troubleshoot BMS/EMS/SCADA (Siemens, Allen-Bradley, Johnson Controls): tune PID loops, rationalize alarms, adjust sequences of operation, and document via change control.
• Coordinate calibration (temperature, RH, pressure, flow) and support IQ/OQ/PQ with solid validation documentation.
• Drive investigations and CAPA using RCA methods (5-Why, Fishbone) and maintain impeccable cGMP/GDP records and SOPs.
• Champion audit readiness (FDA/EU GMP) and keep systems in a validated state.
• Improve energy and performance: VFDs, heat recovery, demand-based ventilation, and smart control strategies.
• Plan and execute outages, turnarounds, and capital projects with contractors, materials, and risk assessments.
• Lead safety culture (LOTO, confined space, hot work, arc-flash; EPA 608 refrigerants) and mentor junior technicians.
• Manage spares and CMMS workflows; partner closely with Quality, Manufacturing, Engineering, Validation, and Operations.

Requirements

• Education: Technical diploma or apprenticeship in HVAC, Mechanical, or Building Services; bachelor’s degree in Mechanical or Building Engineering is a plus.
• Experience: 6–10+ years in HVAC maintenance, including 3–5 years in pharma, biotech, or regulated GMP environments; cleanroom HVAC experience is essential.
• Technical strengths: Proficiency with AHUs, chillers, boilers, hydronics, humidity control, HEPA systems, and strong controls/BMS knowledge (PID, trends, data integrity).
• GMP know-how: Familiarity with ISO cleanroom classifications, airflow visualization/smoke studies, pressurization cascades, and aseptic requirements.
• Validation: Experience with sensor calibration, IQ/OQ/PQ, GDP, CAPA, and Change Control.
• Diagnostics: Advanced troubleshooting skills, basics of vibration analysis and thermography; proficiency with instrumentation (anemometers, micromanometers, particle counters, data loggers).
• Certifications: Safety training preferred; manufacturer training on chillers/controls and GxP/cleanroom courses are a plus.
• Soft skills: Clear communication, teamwork, stakeholder management, decisiveness under time pressure, and meticulous documentation.
• Physical: Ability to lift 50 lbs, work on ladders/heights/mechanical spaces, wear PPE for labs/cleanrooms, and participate in after-hours/on-call rotation.

Benefits

• Eligibility for various incentives, including short-term incentive bonuses, equity-based awards (for salaried roles), and commissions (for sales roles).
• Qualified retirement programs.
• Paid time off (vacation, holiday, and leaves).
• Health, dental, and vision coverage in accordance with applicable plans.

Pay

The annual base pay for this position ranges from $71,749.60 to $107,624.40.
