Job Description

A day in the life

You start your day with a walkthrough of the shop floor—listening for spindle chatter, scanning coolant levels, and reviewing the preventive maintenance schedule you keep relentlessly on track. A lathe is flagging an alarm; you trace it to a sensor and have it swapped and verified before production misses a beat. By mid-morning, you're aligning a 5-axis mill, tightening up backlash, and logging findings in the CMMS. After lunch, you coordinate a vendor for a compressor service, help riggers position a new machine, run airlines and network cabling, and finish your shift with a root-cause review of a recurring drive fault so it doesn’t come back.
