CNC Machine Tool Reliability Specialist

Job Description

Join Kearfott — A Century of Motion Control Leadership

Since 1918, Kearfott Corporation has pioneered precision motion control and inertial navigation for the world’s most demanding Aerospace and Defense applications. Our products guide missions across sea, land, air, and space, and our reputation for quality and innovation is trusted globally. A Day in the Life

You arrive to a well-equipped manufacturing floor where uptime matters. Your morning starts by reviewing overnight maintenance logs, prioritizing preventive tasks across mills, lathes, routers, grinders, and advanced machining centers. Midday, you’re deep into diagnosing a spindle vibration issue, reading schematics and wiring diagrams, checking servo motor feedback, and tuning Fanuc parameters to restore peak performance. Before the day ends, you commission a newly installed CNC cell, document service actions, and collaborate with production, engineering, and quality to lock in repeatable, reliable throughput.

Inspection and replacement of wear components: bearings, ball screws, servo motors, belts, and spindles.

Installation, alignment, calibration, and commissioning of new CNC machines and related systems.

Accurate documentation: maintenance logs, service records, and work procedures.

Cross-functional problem solving with production, engineering, and quality teams to resolve performance issues.

Interpretation of manuals, schematics, blueprints, and wiring diagrams to guide diagnostics and repairs.

Strict adherence to safety standards, including lockout/tagout and company policies.

Continuous improvement recommendations to enhance uptime and reliability. Required Qualifications

High school diploma or equivalent; a technical degree/certification in industrial maintenance, mechatronics, or related field is a plus.
