Computer Numerical Control Programmer

We are seeking an experienced CAM Programmer with strong Mastercam skills to join our precision manufacturing team supporting the defense industry. This individual will be responsible for developing, optimizing, and troubleshooting CNC machining programs to manufacture high-precision components in accordance with engineering drawings, customer specifications, and stringent quality requirements.

The ideal candidate has hands-on experience in a CNC machine shop environment, a strong understanding of machining processes, tooling, feeds and speeds, and the ability to collaborate with machinists, manufacturing engineers, and quality personnel to ensure efficient and accurate production.

Key Responsibilities

• Develop, program, and optimize CNC machining toolpaths using Mastercam.
• Create and modify CNC programs for milling, turning, and other machining operations as applicable.
• Interpret engineering drawings, CAD models, GD&T, and manufacturing specifications.
• Select appropriate cutting tools, fixtures, machining strategies, feeds, and speeds.
• Collaborate with CNC machinists and shop personnel to ensure programs are practical, safe, and production-ready.
• Perform program verification, simulation, and collision checks to minimize machining errors and reduce scrap.
• Troubleshoot machining issues and revise programs to improve cycle times, accuracy, and overall efficiency.
• Support first-article inspections, prototype builds, and production runs.
• Maintain accurate documentation and revision control for CNC programs and setup instructions.
• Identify opportunities for continuous improvement, including reducing setup times, improving tool life, and increasing machine utilization.
• Ensure all components meet applicable quality standards, customer requirements, and defense manufacturing specifications.
• Follow established safety procedures and maintain compliance with applicable manufacturing and quality processes.

Required Qualifications

• Proven experience as a CAM Programmer, CNC Programmer, or similar role in a precision machine shop.
• Strong working knowledge of Mastercam for CNC programming.
• Experience programming CNC milling machines; multi-axis programming experience is a plus.
• Ability to interpret engineering drawings, CAD models, GD&T, and machining tolerances.
• Strong understanding of machining practices, cutting tools, workholding, feeds and speeds, and material properties.
• Experience troubleshooting CNC programs and supporting machinists on the shop floor.
• Familiarity with CNC machine controls and post-processors.
• Strong attention to detail and commitment to producing high-quality, precision components.
• Ability to work independently while collaborating effectively with production and engineering teams.

Preferred Qualifications

• Experience in defense, aerospace, or other highly regulated manufacturing environments.
• Experience machining tight-tolerance components and complex geometries.
• Familiarity with 3-axis, 4-axis, or 5-axis CNC machining.
• Experience working with metals such as aluminum, stainless steel, titanium, and other aerospace-grade alloys.
• Knowledge of AS9100, ISO 9001, or similar quality management systems.
• Experience supporting first-article inspection, process validation, and production documentation.
• Understanding of ITAR-controlled manufacturing environments, where applicable.
