• Complete required manufacturing, inspection, traceability, and production documentation accurately and promptly.
• Follow applicable AS9100 procedures, customer requirements, and document-control practices.
• Handle composite parts and aluminum tooling in a manner that prevents damage, contamination, and foreign-object debris.

Minimum Required Qualifications

• High school diploma or equivalent.
• At least two years of CNC machining experience, including machine setup and operation using existing CNC programs.
• Understanding of CNC machine setup, part and tooling changeover, program selection and machine monitoring procedures.
• Ability to interpret engineering drawings, technical specifications, work instructions, tolerances, and applicable GD&T requirements.
• Experience using calipers, micrometers, gauges, and other precision measuring instruments.
• Working knowledge of tooling, fixtures, workholding, offsets, feeds, speeds, and machining calculations.
• Ability to use computers and electronic manufacturing or production-record systems.
• Ability to understand and communicate work-related information and follow written and verbal instructions.

Preferred Qualifications

• Machining or CNC certification.
• Experience with Mastercam or comparable CAD/CAM programs.
• Experience operating 4- or 5-axis CNC machining centers preferred; training may be provided to otherwise qualified candidates
• Experience machining aluminum tooling and trimming composite materials.
• Aerospace manufacturing or AS9100 experience.

Work Environment And Physical Requirements

• Regularly stand and walk for extended periods while operating and monitoring CNC equipment.
• Frequently use hands and fingers to operate machine controls, computers, tools, fixtures, and measuring instruments.
• Frequently reach, bend, stoop, and position materials, tooling, and parts during machine setup and operation.
• Possess the manual dexterity and hand-eye coordination necessary to perform machine setup, tool changes, inspection, and precision measurement.
• Lift, carry, push, pull, or reposition tooling, fixtures, raw materials, parts, and equipment weighing up to 50 pounds independently and heavier items with assistance or appropriate lifting equipment.
• Work is performed in an active manufacturing environment, with regular time spent in the CNC machining and production areas.
• Regular exposure to operating CNC machines, cutting tools, moving mechanical components, powered industrial equipment, and material-handling activities.
• Exposure to elevated noise levels from machining, trimming, dust-collection systems, compressed air, and other manufacturing equipment. Hearing protection may be required in designated areas.
• Required to wear applicable personal protective equipment, which may include safety glasses, hearing protection, safety footwear, gloves, protective clothing, and respiratory protection when required by the task or designated work area.
• Reasonable accommodations may be made to enable qualified individuals with disabilities to perform the essential functions of the position.
