Senior HVAC Maintenance Technician
About The Position
The Senior HVAC Maintenance Technician will lead preventive, predictive, and corrective maintenance across various HVAC systems including AHUs, chillers, boilers, heat exchangers, VAVs, exhaust, dehumidifiers, and split systems. This role is crucial for maintaining temperature, humidity, airflow, and pressurization in GMP spaces, ensuring cleanroom compliance with ISO 14644 standards. The technician will optimize and troubleshoot BMS/EMS/SCADA systems, coordinate calibration, and support validation processes. They will also drive investigations and CAPA using RCA methods, champion audit readiness, and improve energy efficiency. Planning and executing outages, turnarounds, and capital projects, while leading safety culture and mentoring junior technicians, are key responsibilities. The role involves managing spares and CMMS workflows, collaborating with various departments, and directly supporting compliant manufacturing and product quality.
Requirements
- High school diploma/GED
- 6–10+ years in HVAC maintenance, including 3–5 years in pharma/biotech or regulated GMP environments
- Cleanroom HVAC experience is essential.
- GMP know‑how: ISO cleanroom classifications, airflow visualization/smoke studies, pressurization cascades, aseptic requirements.
- Technical strengths: AHUs/chillers/boilers/hydronics, humidity control, HEPA; strong controls/BMS proficiency (PID, trends, data integrity).
- Validation: Sensor calibration, IQ/OQ/PQ, GDP, CAPA, Change Control.
- Diagnostics: Advanced troubleshooting, basics of vibration analysis and thermography; instrumentation (anemometers, micromanometers, particle counters, data loggers).
- Soft skills: Clear communication, teamwork, stakeholder management, decisive under time pressure, meticulous documentation.
- Physical: Lift 50 lbs, ladders/heights/mechanical spaces, PPE for labs/cleanrooms, after-hours/on-call rotation.
Nice To Haves
- Technical diploma/apprenticeship in HVAC/Mechanical/Building Services
- Bachelor’s in Mechanical/Building is a plus.
- Certifications: Safety training preferred; manufacturer training on chillers/controls and GxP/cleanroom courses are a plus.
Responsibilities
- Lead preventive/predictive/corrective maintenance across AHUs, chillers, boilers, heat exchangers, VAVs, exhaust, 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/capital projects with contractors, materials, and risk assessments.
- Lead safety culture (LOTO, confined space, hot work, arc-flash; EPA 608 refrigerants) and mentor junior techs.
- Manage spares and CMMS workflows; partner closely with Quality, Manufacturing, Engineering, Validation, and Operations.
