MANUFACTURING ENGINEERING INTERN, CNC MACHINING (SUMMER 2027)

Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation. By treating manufacturing as a single integrated system, we unlock a new era of innovation where complex hardware is designed, built, and scaled without limits.

As a Manufacturing Engineering Intern (CNC Machining), you will play a critical role in achieving Freeform’s goal of becoming the world leader in the manufacturing of high-value metal 3D printed parts. You will be responsible for developing, implementing, and optimizing CNC programs for precision machining operations as well as working closely with our engineers and machinist to establish machining standards for Freeform’s high-volume, vertically integrated machining workflow.

What you'd do

Assist in developing, implementing, and optimizing CNC programs for complex metal components, including post-processing of 3D printed parts
Support programming, setup, and refinement of operations on multi-axis CNC machines (DMG Mori and Haas)
Interpret CAD models, technical drawings, and GD&T specifications to help create precise machining programs
Help select and evaluate cutting tools, speeds, feeds, and machining strategies for efficiency and repeatability
Assist in troubleshooting CNC programming issues, collaborating with machinists and design engineers
Help create, maintain, and update CNC program libraries, tool databases, best practices, and process documentation
Contribute to process improvement projects that increase productivity, reduce cycle times, and improve machine utilization
Collaborate with additive designers on custom workholding and help identify whether design or process changes are the right fix for a given issue
Support the design and deployment of automation solutions that enhance quality control and production rates
Work on the production floor to gain hands-on experience with machining, setup, and troubleshooting

What they want

Currently enrolled in a bachelor’s degree in mechanical or aerospace engineering from an ABET accredited university or college
Exposure to CNC programming and machining through coursework, labs, makerspace, internships, or collegiate engineering clubs (e.g., Formula SAE, Baja, rocketry, robotics)
Familiarity with Geometric Dimensioning and Tolerancing
