The ideal candidate will have solid experience with Okuma 5‑axis and Haas vertical machining centers, with the ability to program, prove‑out, and optimize machining operations in a fast‑paced aerospace environment.

This position is full‑time onsite, Monday–Friday.

• Develop CNC machining programs and produce NC code in Mastercam for complex aerospace components.
• Select cutting tools best suited for materials, geometry, and tolerance requirements.
• Create and maintain detailed setup sheets, operation‑specific prints, and inspection criteria (process control documents).
• Thoroughly document all manufacturing processes for repeatability and future use.
• Perform research and development machining projects as assigned by the Machine Shop Manager.
• Help develop new ideas to increase productivity, improve quality, and reduce rejects.
• Set up CNC milling machines (multi‑axis) and complete first‑piece runs, including first‑piece inspections.
• Operate CNC milling machines for prototype and production runs, performing required in‑process inspections.
• Use precision inspection equipment to verify every part meets dimensional and quality requirements.
• Troubleshoot machining, tooling, and process issues to ensure maximum uptime and part quality.
• Support machine operators when questions or problems arise.
• Select, specify, and manage cutting tools and holders optimized for aerospace materials.
• Maintain tool inventory levels and collaborate with Purchasing to ensure availability and cost control.
• Evaluate new tooling technologies, vendors, and strategies to improve performance, reduce cost, and enhance tool life.
• Establish and maintain standardized tool libraries and Mastercam toolpath templates to improve consistency and repeatability.
• Design and manufacture required fixtures for machining and assembly operations.
• Maintain standardized tool management systems and documentation.
• Perform routine maintenance on CNC machine tools as needed.
• Ensure machining processes enable unattended or lights‑out machining whenever possible.
• Ensure all machining operations comply with AS9100 and customer‑specific aerospace requirements.
• Maintain proper documentation, traceability, and revision control.
• Collaborate with Quality Assurance to address nonconformances and implement corrective actions.
• Follow all company safety requirements when working with cutting tools, fixtures, and CNC machinery.
• Keep the Machine Shop Manager informed of issues that could impact quality, productivity, or delivery.
• Work closely with machinists, supervisors, engineers, and quality inspectors to resolve technical challenges.
• Provide technical support during program prove‑outs and machine operator training.
• Attend or conduct meetings as required to support planning, improvement, and problem‑solving.
• Perform any additional duties assigned by the Machine Shop Manager.

• Minimum 5 years of CNC machining or programming experience in aerospace or high‑precision manufacturing.
• Strong experience programming with Mastercam (multi‑axis milling).
• Hands‑on CNC setup experience, preferably on Okuma 5‑axis and Haas vertical mills.
• Strong understanding of GD&T, blueprint reading, and aerospace documentation standards.
• Familiar with AS9100 quality system requirements.
• Proficient with precision inspection tools and methods.
• Excellent problem‑solving, communication, and organizational skills.

• Skilled in fixture design, tool selection, and machining strategy optimization.
• Experience with Okuma OSP controls and G‑code editing.
• Familiarity with lean, 5S, or Six Sigma methodologies.
• Ability to thrive in a high‑mix, low‑volume aerospace environment with tight tolerances.
• Strong analytical thinking and process‑oriented mindset.

• Climate‑controlled precision machine shop.
• Frequent standing, walking, and lifting up to 50 lbs.
• Close collaboration with engineers, programmers, machinists, and inspectors to meet mission‑critical aerospace standards.
