CNC Programming Engineer

Job Description Location Profile

Aerospace Dynamics International, Inc. (ADI) manufactures machined parts and assemblies for the commercial and military aerospace industries. It offers structural components, caps, panels, bulkheads, fittings, longerons, spars, chords, wing ribs, thrust reversers, structural machine parts, manufacturing tooling and stretch form blocks.

ADI was acquired by PCC in April 2014. The company has received significant capital investments since the acquisition and has a highly positive growth trajectory ahead. Comprising seven facilities on its campus in Valencia, CA, ADI has over 240 full-time employees on staff.

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 work holding 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.

• 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, work holding 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, work holding, 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, work holding, 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.

• 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,…
