Job Description

Precision Mold CNC Programmer–Machinist A day in this role

You start by reviewing the tool room schedule and CAD models, then set up your next operation—dialing in workholding, selecting cutters, and posting clean G-code from Mastercam. As parts run, you verify critical features with micrometers, bore and indicator gages, and refine cycle times. When a production tool needs a quick repair, you pivot, collaborate with Toolmakers and Engineers, and machine the replacement component to spec—keeping quality, delivery, and safety front and center.

SMC Ltd. partners with leading healthcare innovators across Medical Device, Diagnostics, Pharmaceutical, and Drug Delivery. With manufacturing sites in the United States, Costa Rica, India, and the United Kingdom, we help customers launch and scale groundbreaking products. Our end-to-end capabilities span design and engineering; thermoplastic and medical micro molding; liquid silicone injection molding (LIM); fill-finish and combination products; full device assembly; validation; packaging and labeling; supply chain; quality systems; and program management.

We combine world-class manufacturing with responsive, hands-on collaboration to solve complex problems and deliver life-changing solutions.
