Job description

Own Your Impact from Day One

At GTC, every eligible full-time team member shares in our success. Through our Ownership For All program, you gain an ownership stake as soon as you join. Your results power our growth—and your own.

A Day in This Role

You start your morning walking the production floor, listening for changes in spindle tone, checking vibration logs, and reviewing last night’s maintenance tickets. A horizontal mill is due for a preventive alignment, a lathe flagged an encoder fault, and a grinder needs a lubrication check. By mid-day you’ve returned a downed machining center to service, documented the repair, ordered a replacement hydraulic pump, and coached an operator on best practices. Before you wrap, you verify laser linear checks and schedule a Renishaw ballbar test to lock in circularity.

What Success Looks Like

• All CNC and manual machines are maintained per preventive schedules and manufacturer guidance.
• Safety is non-negotiable—procedures align with OSHA and OEM specifications every time.
• Maintenance logs, PM checklists, and service histories are complete and current.
• Waste of time, motion, and materials is identified and eliminated continuously.
• When the queue is light, you proactively seek meaningful work to elevate uptime and throughput.
• Tasks are executed safely and methodically to meet internal safety benchmarks.

Core Responsibilities

• Diagnose and repair equipment swiftly to minimize downtime and return assets to production.
• Perform scheduled and condition-based preventive maintenance.
• Partner with external service providers when specialized support is needed.
• Source and order parts to complete corrective and preventive work.

Qualifications Education & Experience

• High school diploma or GED required.
• At least 3 years maintaining manual and CNC machine tools.

Technical Depth

• Hands-on knowledge of bearings, ball screws, gearboxes, pumps, hydraulic and lubrication systems.
• Ability to read mechanical drawings to disassemble, rebuild, and reassemble components.
• Proficient with precision alignment using levels, granite squares, and column squares.
• Comfortable interpreting basic electrical schematics.
• Use of a digital voltmeter and oscilloscope for electrical troubleshooting.
• Experience with CNC controls (Siemens, Fanuc, Heidenhain) and onboard diagnostics.
• Knowledge of axis feedback devices: inductosyns, resolvers, encoders, and linear scales.
• Familiar with laser-based linear accuracy checks and Renishaw ballbar circularity testing.

How You’ll Work with Others

• Build strong partnerships with maintenance peers, operators, supervisors, and production control.
• Model a collaborative, can-do attitude and actively help teammates succeed.

Physical & Environmental

• Manufacturing setting with noise, dust, and temperature variation.
• Ability to lift and carry up to 50 lbs.
• Willingness to work extended hours or weekends for urgent repairs.
