Associate CNC Programming & Machining Engineer

Job Summary

We’re looking for an Associate CNC Programming & Machining Engineer to develop and optimize CNC programs and machining processes for complex, precision-manufactured components.

In this role, you’ll translate engineering designs into efficient shop-floor processes by creating CAM programs, refining G-code, selecting tooling and supporting first-article setups.

This is an excellent opportunity for a recent engineering graduate or early-career professional interested in building advanced CNC programming and manufacturing expertise.

Work That Matters

At Chromalloy, your work directly supports aviation safety and reliability.

Our teams repair and manufacture critical aerospace components used across the global aviation industry.

Whether you're improving processes, supporting operations, solving technical challenges, or driving business performance, your contributions help keep aircraft flying safely around the world.

Location: San Antonio, TX

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


* Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering or a related technical field, or an equivalent combination of hands-on precision machining and CNC programming experience.


* 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.
