The CNC Programmer / Setup Machinist is responsible for programming, setting up, and proving out CNC machining processes to ensure efficient, high-quality production. This role combines CAM programming with hands‑on machine setup and first‑piece validation, supporting both new and repeat production work.

• Develop, modify, and optimize CNC programs for 3, 4, and 5-axis mills and CNC lathes using CAM software (e.g., Mastercam, NX, or similar)
• Interpret engineering drawings, GD&T, and specifications to create accurate and efficient machining processes
• Select tooling, work holding, and machining strategies to support optimal cycle times and part quality
• Support new product introduction (NPI) by developing and validating initial machining processes

• Perform complete machine setups including tooling, fixturing, offsets, and program verification
• Run and validate first‑piece parts to ensure conformance to specifications
• Troubleshoot and resolve issues related to setup, tooling, programs, and machine performance
• Establish stable, repeatable setups and clear instructions for operators

• Collaborate with machinists, operators, and cross‑functional teams to ensure efficient production flow
• Monitor and improve cycle times, tool life, and overall process efficiency
• Maintain and update CNC programs, setup sheets, and work instructions

• Identify and implement process improvements including tooling, fixturing, and programming enhancements

• Ensure all parts meet quality standards and customer requirements, including GD&T specifications
• Validate part quality through inspection processes and documentation (e.g., first article, in‑process checks)
• Maintain compliance with all safety, quality, and operational procedures
• Support 5S and overall shop organization standards

• Minimum of five (5) years of combined CNC programming and setup experience (mills and/or lathes)
• Strong proficiency with CAM software (Mastercam, NX, or similar)
• Experience with multi‑axis machining (3, 4, and/or 5‑axis)
• Strong understanding of GD&T, blueprint reading, and machining mathematics
• Proven ability to perform full machine setups and prove‑out new jobs
• Experience working with tight‑tolerance components, preferably in aerospace or similar industries
• Strong problem‑solving skills and attention to detail
• Ability to work collaboratively in a fast‑paced manufacturing environment
• Strong work ethic and commitment to quality and continuous improvement

• Experience with exotic materials (e.g., titanium, tungsten)
• Experience with high‑mix / low‑volume production environments
• Familiarity with multiple machine platforms (Haas, Mazak, DMG Mori, Okuma, etc.)

To adhere to U.S. Government international trade regulations, applicant must be a U.S. Citizen.

Our work environment is fast‑paced and professional while providing continued growth fostered by our commitment to teamwork. We offer comprehensive benefits including PTO, paid holidays, medical, dental and vision insurance, 401K, long‑term and short‑term disability.
