Title: CNC Programmer / Setup Machinist (Mastercam)
Location: Santa Fe Springs, California
Employment Type: Direct Hire – Benefited
Compensation: $32-$36/hr.
Industry: Precision Components Manufacturing
Company Overview
Our client is a long-established custom plastics manufacturer specializing in thermoformed plastic components, CNC machining, fabrication, and finishing for OEM customers across multiple industries including medical devices, instrumentation, telecommunications, and industrial equipment.
The company produces both small and large-format thermoformed parts, many of which require precision CNC trimming, machining, and secondary fabrication before final assembly and shipment.
With more than five decades of manufacturing experience, the company offers a stable environment where experienced machinists work closely with production and engineering teams to support prototype and production programs.
Position Summary
We are seeking a CNC Programmer / Setup Machinist with experience in Mastercam programming and CNC machine setup to support machining operations for thermoformed plastic components.
This role will involve programming, setup, and machining of plastic parts on CNC equipment including a 3-axis router-style mill and CNC lathe. The ideal candidate will have hands-on experience working with G-code programming, Mastercam, and CNC setup, along with the ability to troubleshoot machining processes and optimize programs.
This position also offers a unique mentorship opportunity, as the successful candidate will work directly with the senior programmer/machinist who you will be taking over for in the coming years. The role will involve learning the company’s machining processes, tooling strategies, and programming practices with the goal of eventually assuming broader programming responsibilities.
