BAS Technician – HVAC Monitoring and Controls

We are looking for an experienced and technically proficient Senior BAS (Building Automation System) Technician to lead the operation, maintenance, and optimization of automated HVAC systems in controlled or regulated environments. The ideal candidate will have a strong understanding of HVAC processes, automation controls, instrumentation, and cleanroom compliance. This role requires both technical leadership and hands-on expertise in managing and troubleshooting BAS platforms to ensure continuous, efficient, and compliant system performance.

Key Responsibilities:

1. BAS Monitoring & Optimization

• Operate and monitor HVAC systems through BAS/BMS platforms (e.g., Siemens, Honeywell, Schneider, Johnson Controls).

• Optimize control loops, temperature setpoints, differential pressures, and humidity ranges based on process requirements.

• Diagnose control logic issues, sensor failures, and equipment integration faults.

2. Preventive & Corrective Maintenance

• Lead the maintenance of field-level devices (sensors, actuators, valves, VFDs, dampers) connected to BAS.

• Perform system checks, trend analysis, and resolve discrepancies between BAS data and field equipment.

• Coordinate with mechanical and electrical teams to implement corrective actions and system upgrades.

3. Environmental Control Compliance

• Ensure BAS is configured and functioning to meet cleanroom requirements (e.g., ISO 14644, GMP, HACCP).

• Maintain and monitor parameters for air changes per hour (ACH), pressure cascades, temperature, and humidity across classified zones.

• Support validation and qualification processes for HVAC and automation systems.

4. Alarm Management & Troubleshooting

• Investigate and resolve BAS alarms related to HVAC, environmental conditions, and control logic faults.

• Maintain alarm logs and provide detailed reports and root cause analysis of repeated system issues.

• Support 24/7 alarm escalation protocols in critical process zones.

5. Documentation & Compliance Reporting

• Maintain all control system documentation including logic diagrams, device wiring maps, network architecture, and point lists.

• Use CMMS/BMS to log maintenance activities, alarm trends, and calibration histories.

• Ensure compliance with internal quality standards and external audits (GMP, FDA, ISO).

6. Technical Leadership & Training

• Mentor junior BAS technicians and oversee field installation, commissioning, and verification tasks.

• Conduct technical training on BAS platforms, alarm response protocols, and HVAC control principles.

• Collaborate with engineering, validation, QA, and production teams to support system changes or expansions.

Key Focus Areas:

• HVAC Controls Operation & Automation System Management

• Cleanroom & Process Zone Environmental Control

• BAS Optimization and Troubleshooting

• Control Devices Calibration & Verification (Sensors, Actuators, Dampers, VFDs)

• Documentation for Regulatory Compliance (GMP, ISO 14644)

• Alarm Management and Root Cause Analysis

• Team Mentorship and Technical Leadership

Qualifications:

• Diploma / Degree in Instrumentation, Electronics, HVAC, Automation, or Electrical Engineering.

• 6+ years of experience with BAS/BMS systems, HVAC controls, and automation in a regulated or critical facility.

• Hands-on experience with major BAS platforms (e.g., Siemens Desigo, Schneider EcoStruxure, Honeywell EBI, JCI Metasys).

Preferred Certifications:

• BAS Platform Certification (OEM specific)

• GMP or Cleanroom Behavior Certification

• Instrument Calibration / Validation Training

• LOTO, Electrical Safety, or HVAC Commissioning Certifications
