A day in the life
You start your shift with a quick scan of the maintenance dashboard: a 5-axis VMC shows an intermittent spindle vibration, a lathe needs a servo parameter check, and production is ramping up for a critical aerospace build. You lock out a cell, pull covers, check backlash at the ball screw, verify spindle bearings with a dial indicator, tweak a Fanuc parameter to resolve a following error, and capture the work in the maintenance log. By mid-morning, you’re calibrating a newly installed Haas, collaborating with quality on finish specs, and by afternoon you’re commissioning a router, verifying pneumatics and hydraulics, and handing it back to operations on time.

- Execute preventive and predictive maintenance on mills, lathes, grinders, routers, and machining centers.
- Diagnose and repair mechanical, electrical, hydraulic, and pneumatic faults to return assets to peak condition.
- Work with CNC controls (Fanuc, Haas, Siemens, Yasda, Mazak, etc.), including parameter checks and adjustments.
- Inspect and service components such as bearings, ball screws, servo motors, belts, and spindles.
- Support installs, alignment, calibration, and start-up/commissioning of new CNC equipment.
- Document work thoroughly in maintenance logs, service records, and related documentation.
- Partner with production, engineering, and quality to resolve performance concerns.
- Interpret manuals, schematics, blueprints, and wiring diagrams to plan and execute repairs.
- Follow safety policies and lockout/tagout procedures without exception.
- Identify reliability improvements and drive strategies to reduce downtime.
Required background
- High school diploma or equivalent required; technical degree/certificate in industrial maintenance, mechatronics, or similar preferred.

- Deep knowledge of mechanical systems, electrical circuits, hydraulics, and pneumatics.
- Hands-on experience with Fanuc, Haas, Siemens, Mazak (and similar) controllers.
- Proficient reading blueprints, wiring diagrams, and OEM documentation.
- Comfort using precision metrology tools (micrometers, dial indicators) and diagnostic test equipment.
- Self-directed with strong organization, communication, and problem-solving skills.
- Must be a US Citizen.
Physical demands
- Lift up to 50 lbs.
- Stand, kneel, and work in tight spaces as required.
- Operate safely in a production environment with noise, dust, and machinery.
Preferred extras
- Associate degree or certification in Electrical Technology, Industrial Maintenance, or related discipline.
- OSHA 10/30 or NFPA 70E electrical safety training.
- Experience in aerospace/defense or other high-reliability manufacturing.
- Knowledge of cleanroom practices and ESD controls.
- PLC troubleshooting or basic programming familiarity.
