About the Role

This is a facilities-first maintenance position supporting critical building and utility systems across three food manufacturing sites. The primary focus is keeping HVAC, boiler, compressed air, and ancillary utility systems running reliably through structured preventive maintenance and hands-on diagnostic and repair work. This person is expected to complete assigned PMs on schedule, document findings accurately in the CMMS, and escalate issues to their supervisor when work falls outside their scope. Production equipment support is a secondary but real responsibility; this person will assist the broader maintenance team when workload requires it.

Principal Duties/Responsibilities:

HVAC Systems (Primary Focus)

• Perform preventive maintenance on rooftop units and other HVAC equipment across all three sites, including scheduled roof walks, filter replacements, coil inspections, and belt/pulley checks.
• Diagnose and repair HVAC mechanical and electrical faults, including failed contactors, run capacitors, fan motors, and control boards.
• Test, replace, and calibrate transducers and pressure/temperature sensors.
• Inspect refrigerant circuits; identify and report indicators of refrigerant loss or system underperformance.
• Coordinate with BMS/controls systems where present to verify setpoints and alarm conditions.
• Document all PM completions, findings, and corrective work generated in the CMMS.

Boiler Systems

• Perform water-side PM including chemical treatment testing, blowdown procedures, and water quality documentation (conductivity, pH, hardness).
• Check gauges, sight glasses, and safety device indicators as part of routine rounds; log readings and flag abnormal conditions.
• Inspect general boiler room conditions including piping, valves, and ancillary equipment for visible leaks, corrosion, or wear.
• Maintain boiler logs accurately and consistently.
• Escalate any operational concerns, safety device anomalies, or system irregularities to supervisor or via CMMS work order.

Compressed Air Systems

• Perform PMs on air compressors including oil changes, filter replacements (inlet, oil separator, coalescing), belt inspections, and dryer checks.
• Monitor system pressure, dew point, and air quality; document trends and flag abnormal readings.
• Diagnose compressor faults including pressure regulation issues, moisture carryover, and motor or drive problems.
• Maintain drain traps, aftercoolers, and distribution system components.

Water Filtration

• Replace and document filter cartridges across site filtration systems on scheduled intervals.
• Verify pre/post differential pressure and flag abnormal flow restriction or consumption.
• Maintain change-out logs and coordinate filter supply replenishment.

Monitored Systems — Ammonia, CO2, Fire Suppression

These systems are not serviced in-house. The role requires system familiarity, alert recognition, and clear escalation practices.

• Ammonia refrigeration: understand system overview, recognize alarm conditions, and escalate to supervisor or log in CMMS immediately. No hands-on service work.
• CO2 system: monitor delivery pressure and system status; recognize low-supply or freeze events; escalate to supervisor or log in CMMS for response.
• Fire suppression: understand how the system works; read and interpret panel alerts; reset nuisance alarms and distinguish them from real fault conditions; escalate non-nuisance alerts to supervisor.

Production Equipment Support (Secondary)

• Performs expert level break-fix and preventive maintenance on production and process equipment as workload allows. Includes observing equipment in operation to identify root cause, dismantling devices to access defective parts, examining parts for imperfections, adjusting functional parts and control instruments, and testing devices after repair.
• Identifies and sources parts, supplies, and repair items. Performs evaluations of alternatives to improve cost or reliability.
• Works with Planner/Scheduler to optimize preventive maintenance procedures.
• May be required to set up and operate machining tools including lathe, drill press, and grinder to make or repair parts. May perform welding tasks.
• Troubleshoots and analyzes complex control systems to resolve software, hardware, and configuration problems.
• Utilizes predictive maintenance technologies to collect equipment performance data; observes trends and makes recommendations.

General

• Complies with 5S and housekeeping standards.
• Leads, drives, and participates in CI activities — processes, results, and cost savings using CI tools and methodology.
• Provides assistance to lower level technicians. Performs expert functions as part of training and development.
• Updates records and reviews CMMS history; analyzes data and documents findings.
• Completes and conducts on-the-job training and technical self-study programs for career development.
• Follows all safety-related policies, rules, regulations, technical instructions, and guidelines. Maintains situational awareness and identifies unsafe behaviors and conditions.

Knowledge, Skills, Abilities, & Behaviors Required:

• High School Graduate or equivalent (GED). Associate’s degree with a technical focus preferred.
• 5+ years of experience in facilities or industrial maintenance with a demonstrated focus on HVAC and building utility systems; or 7+ years of general industrial maintenance experience.
• Hands-on experience diagnosing and repairing HVAC equipment at the component level — contactors, capacitors, fan motors, transducers, and control boards.
• Experience with boiler water treatment, safety device testing, and boiler log documentation.
• Experience maintaining industrial air compressors (reciprocating, rotary screw, or both).
• Working knowledge of electrical systems: able to read schematics, use a multimeter, and safely work in panel and motor circuit environments.
• Understands mechanical, fluid power, and control systems. Can analyze problems, evaluate solutions, and perform repairs.
• Comfortable operating at height — roof access, ladders, and lifts.
• Must be able to use basic hand tools and specialized tools as appropriate.
• EPA Section 608 Universal Certification preferred.
• CMMS experience preferred (work order creation, PM documentation, history review).
• Familiarity with ammonia or CO2 refrigeration systems (monitoring and escalation, not servicing) is a plus.
• Wastewater pretreatment or discharge compliance experience is a plus.
• Experience in predictive technologies, vibration analysis, precision alignments, or laser interferometer operations is a plus.
• May be required to travel between sites.

Physical Demands and Working Conditions:

While performing the duties of this job, the employee is regularly required to stand; walk; use hands/fingers to handle, or feel; reach with hands and arms; climb, ascend/descend or balance to heights that may require a ladder or lift; stoop, kneel, crouch, or crawl in confined spaces; and talk or hear. The employee is occasionally required to sit. The employee must occasionally lift and/or move more than 50 pounds. The employee is regularly required to use close vision and color vision. This role works across active food manufacturing facilities with conditions including loud environments, temperature extremes (rooftop, refrigerated areas, boiler rooms), and exposure to cleaning chemicals, compressed gases, and electrical systems. The employee is occasionally exposed to outside weather conditions and risk of electrical shock.
