• 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.

Hands-On Setup, Operation & Troubleshooting

• 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.

Tooling, Fixtures & Equipment

• 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.

Quality & Compliance

• 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.

Cross-Functional Collaboration & Communication

• 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.

QUALIFICATIONS:

• 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.

SKILLS, KNOWLEDGE, AND ABILITIES:

• 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.

PHYSICAL REQUIREMENTS AND WORKING CONDITIONS:

• 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.
