Job Summary

We are seeking a skilled and hands-on CNC Programming Engineer to develop, optimize, and support CNC machining processes for large, complex aerospace structural components. This position is responsible for developing, proving, optimizing, and maintaining CNC manufacturing processes for large-scale aerostructure components produced on multi-axis, multi-spindle, open-bed gantry machining centers. This position will bridge engineering and manufacturing by translating engineering designs into safe, repeatable, and efficient machining processes.

The CNC Programming Engineer will be responsible for CNC program development, CAM programming, tooling and workholding selection, machining strategy, process documentation, first-article/prove-out support, and continuous improvement of existing manufacturing processes.

The ideal candidate combines advanced CNC programming expertise with a strong understanding of the unique challenges associated with large aerospace structures, including long machining cycles, multiple-spindle operations, large work envelopes, thin-wall structures, part movement, material removal strategy, tolerance management, and the machining of large monolithic components.

This is a hands-on engineering position requiring close collaboration with machinists, manufacturing engineering, quality, tooling, maintenance, and design engineering.

Primary Responsibilities

• Develop and maintain CNC programs for production of large structure aerospace components.
• Create CAM programs, toolpaths, setup documentation, and supporting manufacturing instructions from engineering drawings and 3D CAD models.
• Develop robust machining processes for large aluminum and other aerospace structural components, including monolithic structures, frames, bulkheads, spars, ribs, skins, panels, and similar aerostructure components.
• Determine optimum machining strategies, cutting tools, speeds and feeds, workholding methods, and operation sequences.
• Evaluate datum strategies, machining sequence, part orientation, intermediate inspection requirements, and material condition when developing manufacturing processes.
• Support CNC program prove-outs and first-piece machining directly on the manufacturing floor.
• Troubleshoot machining issues related to tooling, toolpaths, workholding, part geometry, machine capability, surface finish, dimensional accuracy, and cycle time.
• Optimize existing CNC programs to improve cycle time, tool life, process capability, quality, and overall manufacturing efficiency.
• Design or support the development of machining fixtures, workholding, soft jaws, and other manufacturing aids.
• Identify opportunities to reduce setups, machining operations, tooling costs, scrap, and operator intervention.
• Develop and maintain standardized setup sheets, tooling lists, CNC documentation, and revision-controlled manufacturing processes.
• Work closely with machinists during new-product introduction, process development, and production troubleshooting.
• Collaborate with Quality Engineering to resolve dimensional and process-related issues.
• Support root-cause investigations and corrective actions associated with machining processes.
• Evaluate new cutting tools, machining technologies, equipment, and manufacturing methods.
• Establish machining best practices and help standardize CNC programming methods across the manufacturing organization.
• Provide technical mentoring and support to CNC machinists and other manufacturing personnel.
• Ensure machining processes comply with applicable safety, quality, and engineering requirements.

Required Qualifications

• Bachelor's degree in Manufacturing Engineering, Mechanical Engineering, Manufacturing Engineering Technology, or a related technical discipline, or equivalent combination of CNC programming and precision machining experience.
• 5+ years of experience with CNC programming, manufacturing engineering, or precision machining.
• Advanced understanding of CNC machining strategies, including:
  • Multi-axis CNC machining
  • High-volume material removal
  • Aerospace structural machining
  • Cutting-tool selection
  • Speeds and feeds
  • Toolpath development
  • CNC machine setup
  • Large-part work holding
  • Datum and locating strategies
  • Process optimization
• Strong understanding of machining challenges associated with large, thin-wall, and monolithic aerospace structures.
• Ability to read and interpret complex engineering drawings, specifications, and 3D CAD models.
• Strong understanding of GD&T and its application to machining and inspection.
• Demonstrated ability to troubleshoot CNC machining processes directly on the manufacturing floor.
• Demonstrated ability to independently take a component from engineering definition through CATIA CAM programming, process planning, tooling, setup development, prove-out, and production release.
• Strong analytical and mechanical problem-solving skills.
• Excellent communication skills and the ability to work effectively with engineering, quality, operations, and shop-floor personnel.
• Strong experience programming 3-, 4-, and 5-axis CNC machining centers.

Preferred Qualifications

• Experience programming large, multi-spindle open bed gantry machines.
