Job description

A day in the life

You walk the line at shift start, scan the maintenance dashboard, and prioritize a PLC-controlled filler that flagged a fault overnight. With the schematic open, you trace the issue through a 3‑phase motor control panel (230–480V), swap a suspect sensor, and bring the machine back online. A hydraulic press is due for preventive service, so you complete inspections, change filters, and verify system pressures. Later, you hop on a forklift to reposition a conveyor section and take a scissor lift up to inspect an overhead pneumatic run. Before wrap-up, you coach a newer tech on SOPs, reinforce safety practices, and log improvement ideas for a small fixture you’re helping design.
