Schedule: On-site

What You’ll Be Doing

• Develop, simulate and verify multi-axis CNC toolpaths using Siemens NX, Mastercam or comparable CAD/CAM software.
• Write, edit and optimize G-code and M-code to improve machining efficiency, accuracy and repeatability.
• Establish cutting parameters, including speeds, feeds and toolpath strategies, based on part geometry, materials and machining requirements.
• Select appropriate cutting tools, workholding methods and machining approaches for complex components.
• Develop CNC fixture concepts that support safe, stable and repeatable machining processes.
• Partner with CNC machinists and operators to prove out new programs and support first-article setups.
• Troubleshoot programming, setup, tolerance and machining issues directly on the shop floor.
• Interpret engineering drawings, GD&T requirements and material specifications to ensure programs meet technical requirements.
• Investigate machining errors and revise programs or processes to reduce scrap and rework.
• Identify opportunities to improve cycle times, tool life, process capability and overall machining performance.
• Document CNC programs, setup requirements and process changes to support consistent execution.

What We’re Looking For

• Foundational knowledge of CNC machining principles, CAM programming and toolpath development.
• Working knowledge of Siemens NX CAM, Mastercam or a comparable platform such as SolidWorks CAM or Fusion 360.
• Basic ability to write, edit and troubleshoot G-code and M-code.
• Understanding of cutting tools, machining parameters, tool geometry and workholding principles.
• Ability to read and interpret technical drawings, engineering tolerances and GD&T requirements.
• Strong analytical and problem-solving skills with the ability to investigate technical issues and develop practical solutions.
• Clear communication skills and the ability to collaborate effectively with engineering, machinists and shop-floor operators.
• Technical curiosity and a willingness to learn new machining methods, software and manufacturing processes.

Nice to Have

• Internship, co-op or hands-on experience in a CNC machining or precision manufacturing environment.
• Experience developing multi-axis CNC programs.
• Familiarity with Siemens NX CAM or Mastercam.
• Exposure to CNC program simulation, verification or post-processing.
• Experience supporting first-article setups, fixture development or machining process improvements.
• Familiarity with aerospace components, close-tolerance manufacturing or regulated production environments.

Work Environment & Physical Requirements

• Work is performed in a manufacturing environment with exposure to machinery, noise, fumes, dust, and varying temperatures.
• Frequent standing, walking, bending, reaching, and moving throughout production areas.
