    Job Title:

    Senior CAD/CAM Programmer - Aerospace & Defense Manufacturing

    Location:

    Anaheim or Walnut, CA

     

    On-site | Full-Time

     

    Overview

     

    We are seeking an exceptional CAD/CAM Programmer with deep expertise in SolidWorks and Mastercam to support elite CNC manufacturing operations producing high-precision Aerospace and Defense components. This role supports critical programs for Boeing, Northrop Grumman, and Lockheed Martin, where accuracy, repeatability, and process discipline are non-negotiable.

     

    The ideal candidate thrives in a high-stakes, zero-defect environment, programming complex parts machined on large-scale CNC gantry machines with extremely tight tolerances and advanced materials.

    Key Responsibilities

    + Develop, program, and optimize complex CNC machining operations using Mastercam for large-format gantry machines (3-, 4-, and 5-axis).

    + Create and modify 3D models and manufacturing data in SolidWorks, ensuring full alignment with engineering intent.

    + Translate Aerospace & Defense engineering drawings, GD&T, and specifications into robust, efficient CNC programs.

    + Program for high-precision, tight-tolerance components, often ±0.0005" or tighter.

    + Optimize toolpaths for accuracy, surface finish, tool life, and cycle time while maintaining strict quality requirements.

    + Collaborate closely with Manufacturing Engineering, Quality, and CNC Machinists to ensure flawless execution.

    + Support first-article development, prove-outs, and production ramp-ups.

    + Apply best practices for fixture design, work holding, probing strategies, and in-process inspection.

    + Ensure all programming meets AS9100, customer-specific, and internal quality standards.

    + Troubleshoot machining challenges and continuously improve processes.

    + Maintain organized documentation for programs, setups, and revisions.

    Required Qualifications

    + 7+ years of CAD/CAM programming experience in Aerospace or Defense manufacturing.

    + Expert-level proficiency in Mastercam (multi-axis, complex surfacing).

    + Strong working knowledge of SolidWorks for part modeling and design interpretation.

    + Extensive experience programming large CNC gantry machines.

    + Proven success machining tight-tolerance, high-precision aerospace components.

    + Deep understanding of GD&T, aerospace drawings, and inspection requirements.

    + Experience with exotic and aerospace-grade materials (e.g., aluminum alloys, titanium, Invar, composites).

    + Strong knowledge of cutting tools, feeds, speeds, and advanced machining strategies.

    + Ability to work independently in a high-accountability, mission-critical environment.

    Preferred Qualifications

    + Experience supporting programs for Boeing, Northrop Grumman, Lockheed Martin, or similar OEMs.

    + Familiarity with probing systems, SPC, and CMM workflows.

    + Experience with large, complex structural aerospace parts.

    + Knowledge of post-processor customization and CNC control optimization.

    + Background in lean manufacturing or continuous improvement initiatives.

     

    What We Offer

     

    + Opportunity to work on cutting-edge Aerospace & Defense programs.

    + A high-performance manufacturing environment with advanced CNC technology.

    + Competitive compensation based on experience and expertise.

    + Long-term stability supporting major defense and aerospace platforms.

    + A culture that values precision, craftsmanship, and engineering excellence.
