CNC Programmer - CATIA

ALIGN PRECISION•Garden Grove, CA

1d•Onsite

About The Position

This role is responsible for translating CATIA V5 design models into machinable toolpaths for complex, close-tolerance structures used in aerospace and defense platforms. The ideal candidate has strong CATIA modeling/surfacing skills combined with hands-on programming experience on large-envelope gantry machines.

Requirements

5+ years of CNC programming experience using CATIA V5 (Manufacturing/Machining workbenches), with a focus on large-part or aerostructure machining
Demonstrated experience programming multi-axis gantry or large-envelope machining centers
Strong proficiency with CATIA V5 surfacing and part design modules in addition to manufacturing modules
Strong understanding of aerospace materials (aluminum alloys, titanium) and their machining characteristics
Proficiency reading and interpreting complex engineering drawings, GD&T, and 3D models
Experience with toolpath simulation/verification software (Vericut or equivalent)
Working knowledge of work-holding and fixturing strategies for large, flexible parts
Familiarity with post-processor logic and the ability to troubleshoot post output
Strong understanding of AS9100 and aerospace quality documentation requirements
Must be able to obtain and maintain any required government clearances/authorizations (ITAR compliance)

Nice To Haves

Experience programming 5-axis simultaneous machining on large gantry platforms
Familiarity with PLM/PDM systems (ENOVIA, Windchill, or similar) for CATIA model management
Experience with composite trimming/drilling programs in addition to metallic structures
Prior experience in a defense or commercial aerospace structures manufacturing environment
Cross-training or working knowledge of Mastercam or other CAM systems
Lean Manufacturing / Six Sigma exposure
Associate's or Bachelor's degree in Manufacturing, Mechanical Engineering, or a related field (or equivalent hands-on experience)

Responsibilities

Develop, test, and optimize 3-, 4-, and 5-axis CNC programs using CATIA V5 (Prismatic/Surface Machining, Advanced Machining workbenches) for large gantry-style machining centers
Program complex aerostructure components including monolithic wing skins, spars, ribs, and large sheet metal detail parts directly from CATIA design models and engineering drawings
Build and maintain manufacturing models, stock definitions, fixture assemblies, and tooling libraries within CATIA
Optimize toolpaths for material removal rates, cycle time, tool life, and surface finish while managing part deflection and thin-wall stability on large structures
Select appropriate cutting tools, feeds, speeds, and work-holding strategies for aluminum, titanium, and composite materials
Collaborate with manufacturing engineering, tooling, and quality teams to ensure programs meet GD&T requirements and first-article inspection standards
Perform program verification and simulation (e.g., Vericut, CATIA NC simulation) to eliminate collisions, gouges, and fixture interference prior to machine floor deployment
Support first-article setup and provide on-machine troubleshooting, including program edits and offset adjustments
Post-process CATIA toolpaths and troubleshoot post-processor output for specific gantry machine controllers
Maintain and update program documentation, setup sheets, and tool lists in accordance with AS9100 and customer quality requirements
Support continuous improvement initiatives to reduce cycle times and improve process capability on large-format work
Participate in DFM (Design for Manufacturability) reviews for new aerostructure programs, providing manufacturing input on CATIA design models
Regular, reliable attendance and punctuality are essential functions of the role.
