A computer numerical control (CNC) programmer develops software programs that direct machines to cut and shape the material into parts and tools. A contract CNC programmer is a freelance position; companies hire you on a short- or long-term contract. As a contract CNC programmer, you work with 3D computer designs, computer-aided manufacturing, and blueprint software. Your responsibilities are to review job orders, design models, perform calculations, determine appropriate tools and speed, generate program code, and run tests. Additional job duties may include operating the machines and checking for compliance with all safety standards. Once the materials are complete, you work with quality control to ensure the products are cut to specifications.
