Title: CNC Technical Maintenance Specialist

Quala is seeking a CNC Technical Maintenance Specialist to join our team that is supporting the prototyping of next generation consumer electronic devices. This is an exciting opportunity to work in a state-of-the-art prototyping lab that is based in Redmond, WA.

As a CNC Technical Maintenance Specialist, you will provide dedicated preventive and corrective maintenance for our CNC machine shop. This role ensures maximum machine uptime, precision, and reliability across a fleet of multi-axis CNC machining centers, high-speed mills, and EDM equipment supporting prototype development for hardware prototyping programs.

This is a hands-on technical role focused exclusively on CNC machine health — distinct from general facility maintenance. The specialist will own the preventive maintenance program, perform calibrations, troubleshoot mechanical and electrical issues, and keep machines running at peak performance.

• Develop and execute preventive maintenance schedules for all CNC equipment, including 5-axis machining centers, high-speed mills, wire/sinker EDM, and supporting equipment
• Perform routine machine calibrations, geometry checks, and accuracy verification (ballbar, laser interferometer, touch probe)
• Monitor and maintain spindle health, way systems, ball screws, and axis drives
• Track and manage consumables (coolant, filters, lubricants, way oil) and maintain inventory levels
• Diagnose and resolve mechanical, hydraulic, pneumatic, and basic electrical issues on CNC equipment
• Troubleshoot CNC control systems including alarms, parameter settings, and servo issues
• Coordinate with OEM service representatives for warranty work, major repairs, and parts procurement
• Perform spindle runout checks, bearing replacements, and alignment corrections

• Implement proactive wear monitoring — tracking spindle hours, axis backlash, thermal drift, and vibration trends
• Maintain detailed maintenance logs and machine history records
• Identify and recommend machine upgrades or modifications to improve reliability and performance
• Support future machine installations, rigging, leveling, and commissioning of new equipment
• Work closely with CNC operators to understand machine performance issues and prioritize maintenance activities
• Coordinate with general facility maintenance to avoid overlap and ensure clear role boundaries
• Support shop safety compliance, including machine guarding, lockout/tagout procedures, and coolant management

• 2+ years of hands-on CNC machine maintenance experience in a production or prototype machining environment
• Demonstrated experience with multi-axis (4- and 5-axis) CNC machining center maintenance and calibration
• Strong mechanical aptitude — ability to diagnose and repair ball screws, linear guides, way systems, spindles, ATC (automatic tool changer) mechanisms, and hydraulic/pneumatic systems
• Working knowledge of CNC control systems — ability to navigate parameters, interpret alarms, and perform basic control-level diagnostics
• Experience with machine calibration tools (ballbar, dial indicators, laser alignment, touch probes)
• Proficiency reading mechanical and electrical schematics
• Knowledge of lockout/tagout (LOTO) procedures and shop safety practices
• Strong documentation skills — ability to maintain maintenance logs and create PM schedules
• Ability to stand, walk, bend, and kneel for extended periods
• Ability to lift up to 50 lbs regularly
• Ability to work in a shop environment with typical noise levels

• Journeyman or equivalent certification in industrial maintenance, millwright, or mechatronics
• Experience commissioning and installing new CNC equipment
• Knowledge of HSK tooling systems and zero-point work holding (e.g., Schunk VERO-S)
