A day in this role

It’s 5:00 a.m. and you’re setting up the day’s work. You review 3D CAD models and engineering prints, plan a mold repair, and schedule a fixture build for an upcoming NPD trial. By mid-morning, you’re collaborating with Molding, R&D, Automation, and Assembly to align on a prototype jig. After lunch, a production line flags a tooling issue—you step in, diagnose the root cause (dull tool and an incorrect feature), and implement corrective action to minimize downtime.

You close the day by updating project memos, estimating time and cost for an upcoming mold modification, and mentoring a production machinist on best practices for grinders and EDM.Schedule Monday–Friday, 5:00 a.m.–3:30 p.m.What you will do Provide strategic technical tooling support to Operations projects, R&D, and New Product Development.
