External Manufacturing Manager

ZwitterCo • Massachusetts, Massachusetts • 1d ago

Overview of Role

ZwitterCo is seeking a proactive and technically skilled and hands-on Manufacturing Technologist to support day-to-day manufacturing operations while driving process consistency, equipment ownership, and continuous improvement.

This role is primarily focused on operating and optimizing key manufacturing processes, as well as ensuring process control, supporting quality outcomes, and troubleshooting issues on the floor.
