Full job description

Operations and Maintenance Specialist (Hands-On) — Food Waste Anaerobic Digester

Shifts: 3:00 PM – 11:30 PM or 11:00 PM – 7:30 AM (Mon–Fri) On-call rotation for emergencies

Company Overview

Chastain’s client transforms packaged food waste into renewable energy and nutrient-rich compost, creating local jobs and healthier neighborhoods. Their award-winning campus operates one of the region’s only integrated depackaging and anaerobic digestion systems.

The Role

This is not a desk job. You’ll be the go-to O&M Specialist on the floor -- installing, aligning, troubleshooting, and improving equipment. If you love solving tough problems with your hands (and a multimeter), you’ll thrive here.

What You’ll Do

  • Install, align, and maintain pumps, tanks, screens, conveyors, filtration, gearboxes, motors, and utilities.
  • Diagnose & repair mechanical, hydraulic, pneumatic, and electrical (24V–480V) systems; coordinate with licensed electricians as needed.
  • Work with industrial controls: PLCs (e.g., Allen-Bradley), VFDs, HMI/SCADA, instrumentation, sensors, and control logic.
  • Perform preventive/predictive maintenance using a CMMS; keep accurate work logs and parts usage.
  • Weld, fabricate, and rig (mild/stainless); safely operate hoists/cranes/forklifts to move heavy equipment.
  • Drive root-cause analysis and continuous improvement to reduce downtime and boost throughput.
  • Enforce LOTO, Confined Space, Hot Work, NFPA 70E, OSHA 1910 and site PPE requirements.

    • What You Bring

  • 3–10 years hands-on experience in industrial maintenance, millwrighting, or mechanical engineering (manufacturing, waste processing, food/beverage, chemicals, or similar).
  • Strong mechanical fundamentals plus working knowledge of 24V–480V equipment and VFDs/controls.
  • Proficiency in welding/fabrication/rigging, reading prints/schematics/P&IDs, and using precision tools.
  • Experience with CMMS, parts kitting, and maintenance planning.
  • Proven people leadership: setting priorities, training, and holding a team to high standards.
  • Valid driver’s license; ability to lift 50+ lbs and work at heights/in confined spaces (with permits).
  • Degree paths: Bachelor’s in Mechanical Engineering (preferred); technical/vocational training strongly valued.

    • Nice to Have

  • Experience with anaerobic digestion, pumps/centrifuges, depackaging systems, or process plant.
  • Allen-Bradley programming, basic ladder logic edits, instrumentation calibration.
  • Forklift/crane/signalperson certifications; CWI or pressure vessel welding experience.

    • Schedule & Working Conditions

  • Primary shift 3:00 PM – 11:30 PM or 11:00 PM – 7:30 AM (Mon–Fri) On-call rotation for emergencies; occasional OT/weekends/holidays during turnarounds or breakdowns.
  • Industrial environment: noise, odors, heat, dust, chemicals; rigorous adherence to safety protocols.
  • On-call rotation for urgent equipment issues.
