Job Description

The CNC Machinist / Programmer is responsible for creating, managing, and optimizing CNC programs using Mastercam for mainly 3-axis milling with occasional 5-axis milling. This role requires an adequate programming background to analyze engineering data and develop tooling strategies that support the broader production team. The CNC Machinist / Programmer sets up and operates milling machines to machine aluminum and trim composite parts, interprets blueprints and engineering specifications, and monitors quality to ensure all work meets customer tolerances and company standards. Candidates with additional experience programming and operating a gantry-style CMM for dimensional inspection are not required but would be a plus. This role would also be responsible for creating setup documentation when requested by supervisor

Duties & Responsibilities

• Create, modify, and store original CNC programs using Mastercam for 3-axis milling machines
• Analyze drawings and design data to determine appropriate tooling, work holding, machine speeds, and feed rates
• Verify and simulate CNC programs against CAD models to ensure accuracy prior to running
• Troubleshoot and resolve program and process issues, coordinating with supervisor and other functional areas.
• Plan, design, and produce work holding and job-specific fixtures as required
• Assist operators and machinists with program processes and provide in-process production support when requested by supervisor
• Ensure parts and tools are loaded correctly and quality is consistently maintained throughout each assignment
• Change and adjust cutters as required to meet quality and tolerance requirements; ensure machinery and tools are properly maintained
• Ensure accurate documentation is entered on Manufacturing Orders, including correct quantities and specification recording
• Focus on continuous improvement through increased throughput and reduced changeover time
• Stay current with new versions of Mastercam and related programming software
• When required, program and operate the company's gantry CMM to perform dimensional inspections and generate inspection reports
• Produce setup documentation, tooling documentation, and shop-aided drafting prints to support operators and machinists when requested by management
• Perform other duties as assigned

Skills & Knowledge

• Expert proficiency in Mastercam CAM software for 3-axis programming. Note: 5-axis a plus
• Strong working knowledge of G-code and CNC machine setup, monitoring, and change-out procedures
• Ability to analyze engineering drawings, blueprints, and design data to develop effective machining strategies
• Proficiency with machine probing for in-process part measurement
• Ability to apply mathematical functions related to machining, tooling design, and dimensional computation
• Experience in both production and prototyping environments
• Strong mechanical aptitude and meticulous attention to detail
• Experience creating setup and tooling documentation to support shop floor operations
• CMM programming and operation experience preferred but not required, ideally with gantry-style or large-format equipment
• Familiarity with GD&T and its application to dimensional inspection is a plus
• Proficient in Microsoft Office (Excel, Word, PowerPoint)
• Effective written and verbal communication skills, with the ability to collaborate across functional teams

Minimum Qualifications

• Associate degree in Machining Technology or equivalent relevant work experience (2–3 years)
• 3–5 years of Mastercam experience with 3-axis programming required
• Excellent knowledge of G-code required
• CMM programming and operation experience preferred but not required
• Ability to lift and/or move up to 25 lbs. frequently
• Ability to stand for extended periods and work in environments requiring ear and respiratory protection
• Self-motivated, self-managed, and capable of working independently or as part of a collaborative team
• Team player who actively contributes to continuous improvement initiatives
• Clear concise communicator with a positive attitude. Ability to be creative collaborator with team
