Our advanced machining environment includes:

• Mazak Variaxis 5-Axis Machining Centers
• Mazak Integrex 100 and 200 with lower turrets
• Mazatrol Programming Systems
• Mastercam CAD/CAM Software
• Advanced Multi-Axis Milling and Turning Technologies

Why This Opportunity Stands Out

• Competitive hourly compensation based on experience
• Overtime opportunities available
• 2nd Shift Differential: Additional 15%
• 3rd Shift Differential: Additional 30%
• Paid training on advanced manufacturing technologies
• State-of-the-art climate controlled facility
• Modern 5-axis and Swiss machining environment
• Multiple affordable health insurance plan options, including no-cost HSA plans for eligible employees
• Dental and vision coverage
• 401 (k) with employer match
• 100% paid uniforms
• 100 hours PTO during your first year of employment
• 7 paid holidays annually
• Employee Assistance Program (EAP)
• Wellness Coach Program Access

What You’ll Manufacture

You will support the production of highly engineered medical device components requiring:

• Complex multi-axis machining strategies
• Precision features and critical geometries

Material include:

• Stainless steel
• Speciality alloys

What You’ll Do

• Develop complete machining strategies for complex medical device components
• Program, setup, and optimize Mazak Variaxis and Integrex platforms
• Create CNC programs using both Mazatrol and Mastercam
• Perform machine setups, prove-outs, and production launches
• Conduct first article inspections (FAIs) and support validation activities
• Establish tooling, fixturing, and workholding requirements
• Troubleshoot machining, tooling, and process-related issues
• Improve cycle times, reduce waste, and increase manufacturing efficiency
• Interpret engineering drawings, GD&T requirements, surface finish specifications, and revision levels
• Support and mentor machinists to ensure low-error, on-time production performance

What You Bring

• Minimum 5 years of CNC programming experience within a precision manufacturing environment
• Advanced Mazatrol programming experience
• Advanced Mastercam experience
• Experience programming and setting up Mazak Variaxis and/or Integrex platforms
• Ability to independently program, setup, prove out, and launch new production jobs
• Strong blueprint reading and GD&T interpretation skills
• Deep understanding of machining mathematics, tooling workholding, and process development
• Proven ability to troubleshoot and optimize manufacturing processes
• Strong knowledge of inspection methods and quality control procedures

Preferred Experience

• Aerospace manufacturing
• Defense or military manufacturing
• Process development and tooling optimization
• Leading or mentoring machinists and technical teams
• Manufacturing engineering education, apprenticeship, or technical training
