Job DescriptionLead Industrial Maintenance Technologist (Hydraulics & PLC Systems)

Location: Chicago, IL (Onsite) | Schedule: Day Shift, 4:00 a.m.–12:30 p.m. | Employment: Full-Time, Direct Hire

A day in the life

You clock in before dawn and scan your CMMS dashboard to prioritize work orders. You assign tasks to junior techs, then dive into a high-pressure hydraulic press that’s showing erratic pressure due to a sticky proportional valve. By mid-morning, you’re reviewing PLC ladder logic to isolate a misbehaving input, swapping a sensor, and validating operation up to 480V. After lunch, you lead a planned overhaul: swapping a gearbox and large bearing, checking alignment, and coordinating heavy rigging to realign the press. You wrap up by auditing spare parts, documenting preventive maintenance, and coaching a newer technician through LOTO best practices—always with OSHA and NFPA 70E top of mind.

What you’ll own

• Troubleshoot, overhaul, and repair multi-stage high-pressure hydraulic molding presses, accumulators, cylinders, directional valves, and proportional pumps.
• Diagnose and repair automated machinery: I/O devices, VFDs, industrial sensors, relays, and PLC-controlled systems up to 480V; read, interpret, and troubleshoot PLC ladder logic.
• Inspect, maintain, and repair steam boiler lines, electric heating platens, temperature controllers, hot oil heating units, and cooling water tower circuits.
• Lead major machinery rebuilds, including replacing large bearings, gearboxes, drive shafts, and automated transport mechanisms; perform safe heavy rigging to relocate or realign molding presses and related equipment.
• Execute, document, and continuously improve preventive and predictive maintenance using a Computerized Maintenance Management System (CMMS).
• Audit parts inventory and maintain accurate maintenance records; lead emergency troubleshooting during active production breakdowns.
• Assign daily work orders, monitor progress, and mentor junior maintenance technicians.
• Adhere to Lockout/Tagout (LOTO), NFPA 70E, OSHA, and all company safety procedures; maintain a clean, organized, and safe work environment; perform additional duties as assigned.

What you bring

• Minimum of 5 years of industrial plant maintenance experience, including at least 2 years in rubber molding, plastic injection molding, or heavy industrial manufacturing.
• Technical trade school degree, vocational certification, or formal mechanical/electrical apprenticeship preferred.
• Hands-on experience with Allen-Bradley and Siemens PLCs; ability to read hydraulic schematics, electrical wiring diagrams, mechanical drawings, and pneumatic layouts.
• Verified Lockout/Tagout (LOTO) training; forklift, aerial lift, and overhead crane certifications preferred.
• Proficiency with digital multimeters, insulation testers, hydraulic pressure gauges, precision micrometers, welding equipment, and heavy rigging tools.
• Intermediate Microsoft Word and Excel skills.

Core strengths

• Expert mechanical, hydraulic, electrical, and PLC troubleshooting capability.
• Calm, decisive problem-solving in a fast-paced production environment.
• Clear communicator and hands-on mentor.
• Safety-first mindset and continuous improvement focus.
• Meticulous documentation and attention to detail.

Physical demands & environment

• Lift, carry, and manipulate up to 75 lbs routinely.
• Climb ladders, work at heights, enter confined spaces, and stand/walk on concrete for 8–12-hour shifts.
• Work around elevated temperatures, steam systems, chemical odors, and high noise while wearing required PPE.
