Job Description

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

• \n7+ 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.

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.
