Senior CNC Programmer role at Eastridge Workforce Solutions

Location:

Buena Park, CA | $30.00 - $50.00 per hour | Full Time – Morning Shift | Direct Hire

The Senior CNC Programmer is responsible for the development, optimization, and implementation of complex CAD/CAM programs for high‑precision casting components. This role requires mastery of CNC programming, a deep understanding of rigorous industrial engineering specifications, and a commitment to precision, operational efficiency, and safety.

• Program Development:
  Create and refine advanced CNC machine programs using industry‑standard CAD/CAM software suites.
• Machining Strategy:
  Develop comprehensive machining strategies for complex, high‑tolerance components, ensuring they align with engineering specs and material requirements.
• Technical Instruction:
  Generate detailed tool paths, setup sheets, and technical instructions for multi‑axis CNC mills, lathes, and integrated machining centers.
• Design Review:
  Analyze 3D models and technical blueprints of cast components to identify critical machining features and potential manufacturing constraints.
• Tooling & Parameters:
  Determine optimal tool selection and calibrate machining parameters (speeds, feeds, and depths) to maximize part quality and tool life.
• Setup & Validation:
  Configure CNC machines with specialized fixtures and tooling; perform initial test runs and "first‑article" adjustments to programs.
• Quality Alignment:
  Partner with Quality Assurance to ensure all components meet strict industry standards, including dimensional accuracy and surface finish requirements.
• Data Management:
  Maintain rigorous documentation of program revisions, process sheets, and standard work instructions.
• Process Optimization:
  Continuously analyze cycle times and workflows to suggest improvements in tooling or methodology that reduce costs and increase throughput by at least 10‑15%.
• Metrology Integration:
  Utilize measurements and in‑process probing data to validate linear dimensions and calibrate fixtures during process development.

• Education:
  
  High School Diploma or equivalent; technical degree or journeyman certification preferred.
• Experience:
  
  Minimum 9–10 years of experience in CNC programming and manufacturing engineering, specifically within high‑precision industries (e.g., Aerospace, Defense, or Medical).
• Software Proficiency:
  Advanced hands‑on experience with major CAD/CAM platforms (e.g., Mastercam, NX, or similar).
• Technical Mastery:
  Expert‑level skill in interpreting CMM results to refine CNC programs.
• Advanced application of in‑process probing techniques for real‑time machining adjustments.
• Extensive experience with 4‑axis and 5‑axis simultaneous machining.
• Technical Knowledge:
  Deep proficiency in G‑code/M‑code, GD&T, and the machining characteristics of advanced alloys and aerospace‑grade materials.
• Compliance:
  Familiarity with international quality standards (such as ISO 9001 or AS9100) and regulatory requirements.

• Mid‑Senior level

• Full‑time
