Technical Manufacturing Associate – Waterjet Cutting (CNC Operator)

The Technical Manufacturing Associate is responsible for the setup, operation, and optimization of CNC waterjet cutting equipment used to fabricate precision elastomer components. This role plays a critical part in Stockwell Elastomerics’ rapid prototyping capability—enabling same-day or next-day delivery of custom silicone gaskets and pads for OEM applications.

You will work with engineering drawings, CAD files, and production schedules to ensure parts meet strict dimensional and performance requirements.
