Minimum of 7+ years of CNC programming experience in a precision aerospace manufacturing environment.
Advanced proficiency in Mastercam and/or Siemens NX CAM, including multi-axis programming and post processor management.
Expertise in machining aerospace materials (e.g., titanium, nickel alloys, hardened steels) with proven capability maintaining tolerances within ±0.001".
Strong understanding of AS9100, aerospace documentation control, and first article inspection requirements (FAI per AS9102).
Familiarity with Fanuc, Siemens, and Haas CNC controls.
Excellent troubleshooting, collaboration, and communication skills with a focus on supporting fast-paced production demands.

Nice To Haves

Hands-on experience setting up and proving out multi-axis CNC jobs.
Knowledge of lean manufacturing and process improvement initiatives (Kaizen, 5S, root cause analysis).
Experience with in-process probing, adaptive machining strategies, and tool life management systems.

Responsibilities

Program and optimize 3-, 4-, and 5-axis machining operations for aerospace components using Mastercam and/or Siemens NX.
Support production teams by troubleshooting machining issues, validating tool paths, and implementing program updates that enhance quality, tool life, and efficiency.
Interpret complex aerospace drawings, 3D CAD data, and GD&T specifications in accordance with ASME Y14.5 and AS9100 quality standards.
Develop tool paths tailored for aerospace-grade materials such as titanium, Inconel, stainless steels, and aluminum alloys.
Collaborate closely with machinists, setup personnel, and manufacturing engineers to ensure consistent production performance and minimize downtime.
Conduct post-processing, toolpath simulation, and verification to ensure collision-free, production-ready programs.
Maintain organized program files, setup instructions, and tool lists for repeat or legacy part production.
Assist in tooling and fixture design reviews, recommending process improvements that reduce cycle times and ensure repeatable accuracy.
Serve as a programming technical resource, mentoring peers and operators on machining techniques and best practices.
