Career Opportunities: CNC Programmer (1546)

The CNC Programmer is responsible for developing, modifying, validating, and optimizing CNC machine programs to manufacture complex, high-precision components. This position requires extensive knowledge of heavy CNC machining, CAD/CAM programming, machining processes, tooling, and blueprint interpretation to ensure quality, efficiency, and on-time production.

Working closely with Engineering, Production, and Machine Shop personnel, the CNC Programmer will translate engineering designs into efficient machine programs while maintaining the highest standards of quality, safety, and manufacturing excellence

Primary Responsibilities:

• Analyze engineering drawings, blueprints, specifications, and GD&T requirements to determine machining methods and programming requirements.
• Develop, modify, validate, and optimize CNC programs using Mastercam, Gibbscam, and other CAD/CAM software.
• Generate efficient toolpaths using appropriate machining strategies, cutting speeds, and feeds to maximize productivity and quality.
• Select appropriate cutting tools, work holding, fixtures, and machining methods for complex manufacturing operations.
• Collaborate with Engineering, Production, and Machine Shop personnel to support machine setup, tooling selection, fixture design, and process validation.
• Plan, coordinate, and support machining projects from program development through production.
• Monitor machining operations and work closely with supervisors and CNC operators to verify program performance, dimensional accuracy, and product quality.
• Troubleshoot CNC programming issues, machining processes, tooling challenges, and manufacturing defects, implementing corrective actions as needed.
• Revise and release updated CNC programs in response to engineering changes, process improvements, or production requirements.
• Evaluate and implement new tooling technologies, machining strategies, and process improvements to reduce cycle times and increase manufacturing efficiency.
• Provide technical guidance and support to CNC operators regarding program execution, machine setup, tooling, and quality requirements.
• Support cross-functional teams, including Engineering, Project Management, Procurement, Estimating, Quality, and Manufacturing.
• Report directly to the CNC Programming Manager.
• Develop CNC machining programs for production components, assemblies, and fabricated parts.
• Create efficient machining strategies and optimized toolpaths for milling, turning, and complex multi-axis machining operations.
• Select tooling and establish machining parameters to maximize productivity, quality, and tool life.
• Collaborate with Engineering and Manufacturing to improve machining methods, reduce cycle times, and increase process efficiency.
• Validate CNC programs through simulation, prove-out, and first-piece inspection prior to production release.
• Monitor production machining results and implement program revisions as needed to improve quality and efficiency.
• Update and maintain CNC programs in response to engineering revisions and manufacturing improvements.
• Assist in fixture design, work holding development, and tooling selection for new and existing products.
• Ensure compliance with company quality standards, manufacturing procedures, and all applicable safety requirements.

Requirements:

• Minimum of five (5) years of CNC programming experience utilizing Mastercam and/or GibbsCAM for milling and turning applications.
• Minimum of five (5) years of hands‑on CNC machining experience in a heavy manufacturing environment.
• Minimum of five (5) years of experience reading and interpreting engineering drawings, blueprints, technical specifications, and GD&T requirements.
• Strong knowledge of heavy machining processes, including milling, turning, drilling, boring, multi‑axis machining, and multi-tasking machining operations.
• Proficiency with CAD/CAM and nesting software, including Mastercam, GibbsCAM, SigmaNEST, SolidWorks, and AutoCAD.
• Ability to create, edit, troubleshoot, and optimize G-code and M-code programs.
• Thorough understanding of machining materials, cutting tools, fixturing, workholding methods, and manufacturing best practices.
• Demonstrated knowledge of CNC machining, CNC programming, burn table operations, manufacturing processes, and continuous improvement principles.
• Strong analytical, troubleshooting, and problem-solving skills with a high level of accuracy and attention to detail.
• Strong mathematical aptitude and ability to perform technical calculations related to machining operations.
• Excellent communication, organizational, and interpersonal skills with the ability to collaborate effectively across production, engineering, and quality teams.
• Experience in a high‑precision manufacturing environment serving nuclear, aerospace, defense, or heavy industrial markets.
• Knowledge of advanced machining technologies, automation, robotics, and continuous improvement methodologies.
• Familiarity with ASME standards, nuclear quality requirements, or other regulated manufacturing environments is highly desirable.
