Position Summary

This role supports plant operations by troubleshooting, maintaining and repairing electrical and mechanical systems and equipment. This role ensures equipment reliability, minimized downtime, and upholds safety standards while contributing to continuous improvement efforts.

Duties/Responsibilities

• Works directly with all departments and management to coordinate maintenance and repair work
• Perform all functions listed under Required Skills below
• Perform Level 1 and 2 Maintenance Technician responsibilities when requested or required
• Support new equipment installation and commissioning as well as equipment decommissioning
• Identify and implement improvements to increase equipment reliability and efficiency, and/or reduce operating costs

Required Skills

Electrical, Automation

• PLC Diagnostics: connect to and navigate PLC software to diagnose complex system logic errors, track flickering inputs and resolve timing conflicts.
• Power Distribution & VFDs: diagnose 3-phase electrical distribution systems up to 480V. Troubleshoot, configure, and tune Variable Frequency Drives (VFDs) exhibiting overcurrent, thermal, or voltage faults.

Welding & Cutting Systems

• Inverter Power Supplies: diagnose and repair heavy-duty industrial multi-purpose inverter welding machines (MIG, TIG, Sub-Arc), including high-frequency boards, IGBT modules, and wire-feeder control circuits.
• Gas Infrastructure: manage and maintain the plant’s bulk gas distribution manifolds (Argon, CO₂, Oxygen, Acetylene). Inspect flowmeters, gas mixers, and high-pressure line regulators to prevent production bottlenecks.

Hydraulics

• Read and interpret complex mobile hydraulic schematics to troubleshoot multi-spooled directional control valves, hydrostatic drive systems, and pilot-operated control circuits.
• Diagnose and repair hydraulic cylinder drift, internal piston bypass leaks, and pressure loss in primary lift cylinders, tilt cylinders, and specialized attachments (e.g., side shifters).

Reliability & Safety

• Root Cause Analysis: lead root cause failure analysis (RCFA) investigations on recurring machine failures to develop permanent engineering solutions rather than temporary fixes.
• Rigging & Facility Safety: inspect and maintain overhead cranes, hoists, and material handling systems. Rig and move heavy machinery safely adhering to strict weight calculations.
• Compliance: ensure absolute compliance with OSHA standards, specialized Lock-Out/Tag-Out (LOTO) protocols for multi-sourcing energy systems, and National Electrical Code (NEC) guidelines.
