Key Responsibilities

• Create and modify CNC programs for milling, turning, grinding, and multi-axis machining centers.
• Interpret engineering drawings, GD&T requirements, specifications, and CAD models.
• Develop machining strategies, tool paths, and setup documentation.
• Select appropriate cutting tools, fixtures, and work-holding methods.
• Optimize cycle times, tooling utilization, and machine performance.
• Collaborate with Manufacturing Engineers, Quality Engineers, and Machine Operators to resolve production issues.
• Verify programs using simulation software and perform first-piece inspections.
• Troubleshoot machining and programming problems to improve product quality and productivity.
• Support process improvement initiatives, lean manufacturing efforts, and cost-reduction projects.
• Maintain compliance with safety, quality, and customer requirements.
• Document and control manufacturing processes and revision changes.

Required Qualifications

• Associate degree or technical certification in Manufacturing Technology, Machining, Mechanical Engineering Technology, or related field, or equivalent experience.
• Experience programming CNC machining centers.
• Proficiency with CAM software such as Mastercam, NX CAM, Fusion 360, Creo, or similar.
• Ability to read and interpret engineering drawings and GD&T.
