Precision Hydraulics Jobs in Indiana (NOW HIRING)

Description

At National Trade Supply, the Maintenance Technician III is a senior-level technical role responsible for keeping our air and water filtration manufacturing facility running safely, efficiently, and without interruption. This position works across the full breadth of facility systems - electrical, mechanical, pneumatic, hydraulic, and fabrication - and is expected to diagnose and resolve complex equipment and facility issues that others cannot. Responsibility for this role extends beyond production machinery to include the physical facility itself: building systems, infrastructure, utilities, and the overall condition of the environment our team works in every day.

This is a hands-on role for a skilled tradesperson who takes pride in precision, is highly motivated, responds with urgency to downtime, and brings the technical depth to handle both planned preventive maintenance and unplanned breakdowns. The Maintenance Technician III serves as a resource for less experienced team members and is expected to lead by example in both safety and craftsmanship.

At National Trade Supply, we operate with a shared set of core values that guide how we work and grow together: Grit, Bias for Action, Critical Thinking, Self-Awareness, and Operational Excellence. These principles shape our culture, influence our decisions, and define what it means to succeed on our team.

• Troubleshoot, repair, and maintain electrical systems including motors, motor controls, drives (VFDs), PLCs, sensors, and wiring up to 480V.
• Read and interpret electrical schematics, wiring diagrams, and ladder logic to diagnose faults.
• Install, modify, and commission electrical panels, control circuits, and instrumentation.
• Maintain facility lighting systems including replacing fixtures, ballasts, and bulbs throughout the building; coordinate lighting upgrades or repairs in production, warehouse, and common areas.
• Ensure all electrical work complies with NEC standards, NFPA 70E, and company safety protocols.

Mechanical

• Perform preventive and corrective maintenance on production machinery including conveyors, laminating equipment, cutting machines, and assembly line equipment used in air and water filtration manufacturing.
• Diagnose and repair mechanical failures including bearings, gearboxes, belts, chains, couplings, and drive systems.
• Perform precision alignment of shafts, pulleys, and couplings using appropriate tools and techniques.
• Read and interpret mechanical drawings, equipment manuals, and technical specifications.

Pneumatic

• Troubleshoot, repair, and maintain pneumatic systems including compressors, air lines, regulators, solenoid valves, cylinders, and actuators throughout the facility.
• Read and interpret pneumatic schematics and diagrams to identify component failures and system inefficiencies.
• Replace and calibrate pneumatic components to restore proper system pressure, flow, and function.

Hydraulic

• Inspect, maintain, and repair hydraulic systems including pumps, cylinders, valves, hoses, fittings, and reservoirs on production and facility equipment.
• Identify and resolve hydraulic leaks, pressure issues, and system failures using schematics and diagnostic tools.
• Perform fluid analysis, filter changes, and system flushes as part of a scheduled preventive maintenance program.

Fabrication

• Design and fabricate replacement parts, brackets, guards, and fixtures using welding equipment (MIG/TIG/stick) and other shop tools.
• Read and work from mechanical drawings, blueprints, and sketches to produce parts to specification.
• Select appropriate materials and fabrication methods to ensure durability, safety, and cost efficiency.

Facility Maintenance

• Serve as the primary point of contact for all facility-related maintenance issues, ensuring building systems and infrastructure are maintained in safe, functional, and professional condition at all times.
• Perform and coordinate repairs to building systems including HVAC units, exhaust fans, rooftop equipment, and ventilation systems; escalate to outside contractors when scope exceeds in-house capability.
• Maintain facility plumbing systems including sinks, drains, toilets, water lines, and water heaters; identify and resolve leaks, blockages, and pressure issues promptly.
• Inspect, maintain, and repair facility doors, dock doors, dock levelers, roll-up doors, and entry hardware; coordinate preventive maintenance on dock equipment to ensure reliable daily operation.
• Maintain interior and exterior facility conditions including floors, walls, ceilings, and roof integrity; identify and report structural concerns to the Plant Manager.
• Coordinate and oversee work performed by outside contractors and vendors for facility repairs, inspections, and capital projects; ensure vendor work meets safety requirements and quality standards before sign-off.
• Respond promptly to reported facility issues including leaks, temperature complaints, lighting outages, door malfunctions, and other building concerns; prioritize resolution to minimize disruption to operations.

General Maintenance & Safety

• Execute and document preventive maintenance tasks on a scheduled basis using the facility's CMMS (computerized maintenance management system).
• Respond to emergency breakdowns and equipment failures with a sense of urgency to minimize production downtime.
• Perform and enforce full lockout/tagout (LOTO) procedures on all equipment before maintenance work begins.
• Maintain a clean, organized, and safe work environment in the maintenance shop and throughout the facility.
• Mentor and provide technical guidance to manufacturing team members.
• Communicate equipment and facility status, completed work, and pending issues to the Plant Manager and Production Supervisor.
• Perform all other duties as assigned.

Success in this role looks like a facility that runs without preventable interruptions - every machine operating at specification, every safety system functioning correctly, every building system running reliably, and every breakdown resolved quickly and permanently. The Maintenance Technician III is the technical backbone of our manufacturing operation and the steward of the physical environment our team works in. When something goes wrong - whether it's a downed machine, a failed HVAC unit, or a leaking pipe - this person is who we count on to get it right.
