Mastercam CNC Programmer – Aerostructures (5-Axis)

ALIGN PRECISION; Garden Grove (CA); On-site; USD 90,000 - 140,000; Full time

Job summary

ALIGN PRECISION in Garden Grove is seeking an experienced Mastercam Programmer to develop, optimize, and support CNC programs for large aerostructure parts on gantry mills. You will work from CATIA/NX models and drawings to produce wing skins, spars, ribs, and bulkheads with close tolerances.

The role requires 5+ years of Mastercam experience, multi-axis programming, and familiarity with Vericut, GD&T, AS9100, and ITAR.

Qualifications

• 5+ years CNC programming experience with Mastercam for large-part aerostructure machining.
• Experience programming multi-axis gantry or large-envelope machining centers.
• Strong knowledge of aerospace aluminum and titanium materials and their machining.
• Ability to read complex engineering drawings, GD&T, and 3D models.
• Experience with toolpath simulation/verification software (Vericut or equivalent).
• Knowledge of work-holding/fixturing for large, flexible parts.
• Familiarity with post-processor logic and troubleshooting.
• Strong understanding of AS9100 and aerospace quality documentation.
• Ability to obtain and maintain government clearances/ITAR.

Responsibilities

• Develop, test, and optimize 3-, 4-, and 5-axis CNC programs in Mastercam for large gantry-style machining centers.
• Program complex aerostructure components including wing skins, spars, ribs, and large sheet metal parts from 3D models and drawings.
• Optimize toolpaths for material removal, cycle time, tool life, and surface finish while managing deflection and thin-wall stability.
• Select appropriate cutting tools, feeds, speeds, and fixturing for aluminum, titanium, and composites.
• Collaborate with manufacturing engineering, tooling, and quality teams to meet GD&T and first-article inspection standards.
• Perform program verification and simulation (Vericut) to avoid collisions and fixture interference.
• Support first-article setup and on-machine troubleshooting including edits and offsets.
• Interpret and program from engineering models (CATIA, NX, or similar) and CAD formats.
• Maintain program docs, setup sheets, and tool lists per AS9100 and customer quality requirements.
• Support continuous improvement to reduce cycle times and improve process capability on large-format work.
• Participate in DFM reviews for new aerostructure programs.
• Regular attendance and punctuality are essential.
