Mach Industries is seeking a Machine Maintenance Technician to own the preventive maintenance, troubleshooting, and repair of our CNC machines and supporting manufacturing equipment. You will ensure our equipment remains safe, reliable, and capable of supporting both rapid development and production operations.

This is a hands-on role requiring strong mechanical and electrical troubleshooting skills, practical experience servicing CNC equipment, and the ability to independently manage maintenance priorities across a growing machine shop. You will establish maintenance schedules, diagnose machine alarms and alignment issues, complete repairs, and coordinate with equipment manufacturers when specialized service is required. Working closely with Manufacturing Engineering, Production, and Quality, you will help reduce unplanned downtime and prevent recurring equipment failures.

• Own preventive maintenance across CNC mills, lathes, multi-axis machining centers, and supporting shop equipment. Develop and execute maintenance schedules based on manufacturer recommendations, equipment usage, and operating conditions.
• Diagnose and resolve machine alarms, tool-change faults, spindle issues, axis positioning faults, and mechanical or electrical failures using machine diagnostics, service documentation, and systematic troubleshooting.
• Troubleshoot tool changer, turret, and spindle alignment issues. Perform adjustments and recovery procedures within manufacturer guidelines, escalating complex repairs when necessary.
• Inspect, maintain, and repair lubrication, coolant, hydraulic, pneumatic, filtration, and chip-handling systems, including associated pumps, sensors, hoses, valves, and connections.
• Investigate abnormal noise, vibration, temperature, leaks, and repeat alarms. Identify underlying causes and implement corrective actions rather than relying on repeated resets or temporary fixes.
• Coordinate manufacturer and third-party service visits, communicate fault history and diagnostic findings, manage repair follow-through, and verify completed service work.
• Verify machine function following maintenance, repairs, or suspected collision events. Partner with Manufacturing Engineering and Quality to confirm alignment, accuracy, and readiness before returning equipment to production.
• Maintain an equipment register, maintenance calendar, service records, and critical spare-parts inventory. Track downtime and recurring issues to prioritize reliability improvements.
• Support installation and commissioning of new equipment, including maintenance planning, service documentation, and coordination with Facilities and equipment suppliers.
• Train operators on routine equipment checks, proper machine care, and early warning signs. Perform maintenance using established lockout/tagout, electrical safety, and manufacturer service procedures.

• 4+ years of hands-on experience maintaining, troubleshooting, and repairing CNC…
