Job Summary

The CNC Programmer is responsible for developing, optimizing, and maintaining CNC programs for 3-axis, 4-axis, and 5-axis machining centers used in the production of precision sheet metal and machined components. This role plays a vital part in ensuring high-quality, efficient, and consistent part production in accordance with customer requirements and AS9100 standards. The CNC Programmer works closely with engineering, machining, and quality teams to support both prototype and production machining projects.

Key Responsibilities

CNC Programming

• Create, edit, and optimize CNC programs for 3-, 4-, and 5-axis mills and lathes using CAM software (e.g., Virtual Gibbs, or equivalent).
• Interpret blueprints, 3D models, and GD&T specifications to generate accurate toolpaths.
• Optimize feeds, speeds, and cutting strategies to reduce cycle time and improve tool life.
• Post-process programs for compatibility with specific machine controllers and simulate toolpaths to verify accuracy.
• Develop programs that maximize tool life, reduce cycle time, and improve part quality.

Tooling & Setup Support

• Determine appropriate tooling, fixturing, and machining strategies for complex geometries and materials.
• Collaborate with machinists during setups to ensure program accuracy and repeatability.
• Provide detailed setup sheets, work instructions, and fixture documentation.

First Article & Process Validation

• Assist with first article inspections and perform program adjustments as needed to ensure conformity to print.
• Work closely with quality control to resolve discrepancies and refine machining processes
• Participate in root cause analysis and implement corrective actions for any programming-related non-conformances.

Process Optimization

• Review and improve existing programs for efficiency, repeatability, and safety.
• Standardize programming procedures and document best practices for multi-axis operations.
• Identify opportunities to improve machining efficiency, part quality, and program standardization.
• Maintain and update the CNC program library for revision control and traceability.
• Work with manufacturing and engineering teams to streamline production workflows.

Collaboration & Communication

• Coordinate with production supervisors, machinists, and engineers to prioritize jobs.
• Assist in quoting and estimating cycle times for new or revised parts.
• Provide technical support and mentoring to machinists and operators as needed.

Compliance & Documentation

• Ensure all programming and documentation align with AS9100 quality management standards.
• Maintain detailed records of tooling, setups, and revisions.
• Support internal and external audits as required.

Qualifications

Education and Experience

• High school diploma or GED required; technical certification or associate degree in machining, manufacturing, or engineering preferred.
• 3+ years of experience programming CNC mills and/or lathes in a precision manufacturing environment.
• Familiarity with aerospace or defense industry requirements and AS9100 standards is strongly preferred.
• Hands-on experience with 4- and 5-axis machining centers is required.

Skills & Competencies

• Proficient in CAM software (Virtual Gibbs or similar) and solid modeling interpretation.
• Strong understanding of CNC machining processes, cutting tools, and materials.
• Knowledge of G-code, M-code, and various machine controller platforms (e.g., Fanuc, Haas).
• Excellent blueprint reading, GD&T interpretation, and documentation skills.
• Ability to troubleshoot and refine programs to ensure quality and efficiency.

Physical Requirements & Work Environment

• Office and manufacturing floor environment with exposure to noise, machinery, sharp edges and metal components.
• Standing, walking lifting up to 30 lbs, may be required during machine support of part validation.
• Safety protocols, including the use of PPT, must be always followed.

Schedule- Hours: 7:00 AM – 3:30 PM, Monday – Friday (schedule adjustments as needed to meet demand)

Compensation- Hourly Range: $24-38 per hour

• Benefits include shared-cost health care, paid holidays, paid time off, and a 401(k) with company match after a waiting period.
