Metron Machining specializes in complex, high-precision CNC milling for aerospace, defense, space, and energy programs. The company handles work where quality, documentation, repeatability, and on-time delivery genuinely matter.

This is not an operator-level position. Metron is looking for an experienced CNC milling machinist who can take ownership of complete setups, move a job efficiently through first-article approval, and leave behind a stable, documented process that other machinists can run successfully.

Multiple schedules are available, including four-day workweeks and a weekend schedule that pays 40 hours for 36 hours worked. Second and weekend-shift machinists must be highly skilled, self-sufficient, and comfortable working with limited on-site support.

Metron operates with clear standards and accountability. The goal is to prevent problems through disciplined setups, inspection, and documentation—not rely on last-minute firefighting.

• Set up and operate CNC milling machines for complex precision components
• Translate prints, programs, and setup information into reliable machine setups
• Review CAM output and identify potential issues before cutting parts
• Select and validate tooling, fixtures, work holding, offsets, and probing routines
• Adjust speeds, feeds, offsets, and cutting parameters as needed
• Produce and inspect first articles
• Diagnose chatter, dimensional drift, surface-finish problems, and tooling issues
• Maintain tight tolerances and verify parts using precision measuring equipment
• Improve setup documentation for repeat production
• Work with CAM programming, Quality, and Production to resolve problems
• Provide a clear handoff once a job is ready for production
• Escalate technical or quality concerns before they affect delivery

Metron specializes in advanced CNC milling, including multi-axis and 5-axis machining.

You will work with:

• CNC vertical milling machines
• Multi-axis and 5-axis machining processes
• Mastercam-generated programs and toolpaths
• In-process probing
• CMM inspection and first-article documentation
• Calipers, micrometers, indicators, gauges, and other precision inspection tools

• Four-day first- and second-shift schedules
• Three-day weekend schedule paid as 40 hours
• Complex multi-axis and 5-axis CNC milling
• Aerospace, defense, space, and energy work
• Prototype through production machining
• Tight-tolerance, mission-critical components
• Clean and organized shop environment
• Documented, process-driven manufacturing
• Opportunity to help improve setups and shop standards
• ITAR-registered manufacturing environment

• Aluminum
• Stainless steel
• Titanium
• Inconel
• Nickel-based alloys
• Other aerospace and defense materials

Required

• Strong CNC milling setup and machining experience
• Ability to own a complete setup from initial preparation through first-article approval
• Strong blueprint-reading and dimensional-inspection skills
• Experience selecting tooling, setting offsets, and validating work holding
• Ability to troubleshoot chatter, tolerance drift, finish issues, and other machining problems
• Understanding of how speeds, feeds, tooling, fixtures, and setup decisions affect the finished part
• Ability to document setups clearly and consistently
• Reliable judgment and a willingness to stop and elevate when something is not right
• Ability to meet ITAR eligibility requirements
• Ability to successfully complete a background check

For second or weekend shift

• Must be highly skilled and self-sufficient
• Must be comfortable working with limited on-site supervision or technical support
• Must be capable of resolving most normal setup and machining issues independently

Preferred

• Multi-axis or 5-axis milling experience
• Experience reviewing or working with Mastercam-generated programs
• Aerospa…
