Job description

Position Overview: We are seeking a high-caliber Maintenance Supervisor to lead our facility's maintenance operations. The ideal candidate has a strong mechanical background in heavy industrial machinery, combined with solid, hands-on industrial electrical troubleshooting skills. You will be responsible for keeping our production floor running smoothly, managing a small crew of technicians, and driving project implementation to fruition.

Key Responsibilities:

• Hands-On Mechanical Maintenance: Act as a technical resource for heavy mechanical equipment repairs. Diagnose, overhaul, and repair hydraulic systems, high-torque gearboxes, pneumatic lines, pumps, conveyors, and high-temperature furnace components.
• Team Leadership & Management: Lead, schedule, and assign daily work orders to a small team of multi-craft technicians. Enforce strict safety protocols, including OSHA standards, Lockout/Tagout (LOTO), and job hazard assessments. Alongside the Director of Operations manage third-party contractors during major equipment overhauls.
• Electrical Troubleshooting & Controls: Systems-level electrical troubleshooting. Diagnose issues within 480V 3-phase power systems, motor control centers (MCCs), VFDs, and automated machine control panels. Must be comfortable reading schematics to isolate electrical vs. mechanical faults.
• Data Analysis and Capital Equipment End of Life Evaluation: Using our digital maintenance tracking system, review and analyze the data on equipment and workorders. Alongside the Director of Operations, use this data to identify future capex needs and requirements.

Required Qualifications & Mindset:

• The Experience: Minimum 5-7 years of experience in heavy manufacturing, industrial processing, foundry, or milling environments.
• The Technical Balance: A strong mechanical baseline (hydraulics, welding/fabrication, rigging, power transmission) coupled with confident, hands-on industrial electrical experience.
• The Leadership: Minimum 2 years of experience in a supervisory, crew lead, or shift foreman role. You must know how to earn the respect of a seasoned maintenance crew by being willing to get your hands dirty when a critical machine goes down.

Why This Role is Different:

We don't want a manager who sits behind a desk analyzing spreadsheets all day, nor do we want a technician who only looks at their own assigned tasks. We need a partner on the floor who can lead our team by example, troubleshoot a complex mechanical failure under pressure, and strategically plan out the next week's maintenance to eliminate unplanned downtime alongside the guidance of the Director of Operations.
