In this role you will: 

HVAC and Mechanical Systems

• Operate, maintain, and troubleshoot air handling units serving classified and unclassified spaces, including supply and return fans, VFDs, chilled water and hot water coils, reheat, humidification, dehumidification, economizers, and control and isolation dampers.

• Maintain terminal air devices and airflow control components, including VAV/CAV boxes, actuators, flow stations, and terminal HEPA housings.

• Perform filter management across the site: differential pressure monitoring, prefilter and final filter change-outs, and HEPA change-out support including coordination of post-change certification.

• Maintain supporting utilities and equipment: chilled water and hot water pumps and loops, boilers, cooling towers, DX and split systems, compressed air, condensate systems, and building steam where applicable.

• Execute mechanical preventive maintenance to schedule, including belt and sheave replacement and alignment, bearing lubrication, coil and drain pan cleaning, vibration and amperage checks, and sensor verification.

• Perform refrigeration maintenance and repair on DX systems, split systems, condensing units, and chilled water equipment, including compressor, metering device, and refrigerant circuit troubleshooting using superheat and subcooling analysis.

• Perform refrigerant handling in accordance with EPA Section 608 requirements, including leak detection and repair, recovery, evacuation, charging, and required recordkeeping.

• Support maintenance and monitoring of laboratory and GMP cold storage equipment, including refrigerators, freezers, and associated controls and alarms.

• Troubleshoot temperature, humidity, and differential pressure excursions to root cause, distinguishing mechanical failure from control, sensor, calibration, and load-driven causes.

• Take and interpret field readings using manometers, anemometers, flow hoods, psychrometers, tachometers, clamp meters, and refrigerant gauges. Support air balance activities and verify balanced conditions after system work.

Controls and Monitoring

• Monitor facility performance through physical rounds, the building automation system (BAS), and the continuous monitoring system (CMS).

• Respond to BAS and CMS alarms, assess impact to manufacturing and laboratory operations, take corrective action, and escalate per site procedure.

• Interpret BAS graphics and trend data to evaluate system behavior, identify setpoint and sequence issues, and verify that corrective actions returned the system to control.

• Interpret mechanical drawings, P&IDs, control schematics, wiring diagrams, sequences of operation, valve and damper schedules, and equipment submittals in planning and performing maintenance and repairs.

GMP Execution and Documentation

• Execute work orders, SOPs, and work instructions per the maintenance schedule, and document work performed in accordance with Immatics documentation requirements and good documentation practices.

• Understand how pressure cascade, air change rates, temperature, humidity, and filtration integrity relate to product and patient safety, and treat classified-space work accordingly.

• Support deviation and event documentation by providing accurate, timely, factual accounts of system condition, actions taken, and timelines.

• Recognize when planned or emergent work requires change control or qualification impact assessment, and escalate before proceeding.

• Work with and escort qualified contractors performing work on or within the facility, including verification of scope, permits, LOTO, and work area controls in GMP spaces.

• Support equipment moves, room and area setups, along with supporting any operations changes that need to occur in the facility, including verification of utilities and environmental conditions before release.

• Assess multiple simultaneous requirements and prioritize based on impact to manufacturing operations and product quality.

Secondary Functions

• Perform installation and light construction work supporting new equipment and systems in offices, labs, and GMP areas, including duct, piping, and utility tie-ins.

• Coordinate schedules with Manufacturing, Quality, and Laboratory Operations so facility work is performed within operational and cleaning windows.

• Maintain accurate asset, PM, and calibration records in the site CMMS.
