You’ll be the expert customers count on for on-site and in-house support.

What you’ll do

• Run end-to-end installations and commissioning for large CNC equipment.
• Coordinate rigging, placement, and anchoring; perform leveling, alignment, geometric checks, and full calibration.
• Set up and fine-tune CNC controls and motion systems; troubleshoot servos, spindles, hydraulics, pneumatics, and lubrication.
• Diagnose and repair mechanical and electrical faults (to 480V), plus hydraulic and pneumatic issues.
• Read and apply electrical schematics, mechanical drawings, and technical documentation.
• Execute accuracy and performance validation prior to customer acceptance.
• Deliver safety-focused operator training and basic maintenance instruction.
• Document all service actions, repairs, parts usage, and recommendations.
• Provide professional on-site support during multi-day trips (often a full week) and ongoing in-house assistance.

What you’ll bring

• Proven background independently installing and commissioning large CNC machine tools.
• Experience with machining centers, mills, or lathes; familiarity with Fanuc, Heidenhain, Fagor, Siemens, or similar controls.
• Advanced mechanical know-how: bearings, ball screws, alignment, spindles, lubrication systems.
• Electrical troubleshooting skill up to 480V.
• Precision measurement and calibration using indicators, levels, lasers, or comparable instruments.
• Working knowledge of hydraulics, pneumatics, servo systems, and PLC-controlled equipment.
