Job Description
Lead CNC Programmer - Multi-Axis CNC Position Summary The CNC Programmer is responsible for programming, setup, and machining of complex composite and metal components utilizing multi-axis CNC equipment. This role requires advanced expertise in 3-axis and 5-axis CNC machining and full-cycle NC programming in Mastercam, including creating programs from scratch rather than simply editing existing files. The ideal candidate will possess strong hands-on machining experience combined with advanced CAM programming capabilities supporting precision aerospace and high-tolerance manufacturing environments. Key Responsibilities Develop complete CNC programs from scratch in Mastercam for complex 3-axis and 5-axis milling applications Generate and optimize multi-axis tool paths, machining strategies, and post-processing outputs Program, set up, and machine precision composite and metal components to tight tolerances Perform complex machine setups, prove-outs, and first article validations Operate and support a variety of CNC milling and turning equipment Analyze part geometry, tooling requirements, fixturing, and machining processes to improve cycle times and part quality Troubleshoot machining, tooling, programming, and process-related issues Support continuous improvement initiatives related to machining efficiency, tooling optimization, and process capability Coordinate corrective actions to minimize downtime and maintain production schedules Verify program accuracy using simulations, setup sheets, tooling documentation, and machine prove-outs Work cross-functionally with manufacturing, engineering, quality, and production teams Required Qualifications Advanced experience with 3-axis and 5-axis CNC machining environments Strong Mastercam programming experience with the ability to create CNC programs from scratch Experience programming complex multi-axis milling operations, not limited to editing existing programs Hands-on setup and operation experience with CNC mills and/or lathes Ability to read and interpret complex blueprints, GD&T, engineering drawings, and manufacturing procedures Strong understanding of machining composites and/or metal materials Advanced knowledge of tooling, feeds/speeds, work holding, and machining strategies Ability to troubleshoot programming, machine, and tooling issues independently Proficient with precision measuring instruments and inspection methods Strong math and trigonometry skills related to CNC programming and machining Familiarity with NC equipment, post-processors, and CAD/CAM systems Excellent communication and collaboration skills in a production environment Preferred Experience Aerospace or high-precision manufacturing experience Experience with multi-axis lathe and mill-turn programming Experience supporting low-volume/high-mix manufacturing environments Background machining complex composite structures and assemblies Experience with first article inspection and process validation Technical Focus Areas 3-Axis CNC Programming 5-
