Responsibilities
What you'll own
- Develop and validate process windows for new tools on all-electric injection molding presses: pack/hold profile, mold and melt temperatures, cooling, and shot-weight tuning.
- Run scientific-molding studies (viscosity curve, gate-seal, pressure drop) and document the process map the production cell will inherit.
- Lead first-shot reviews with the tooling engineer and optical and mechanical design lead; close the loop on form, birefringence, and gate-related defects before tool steel changes.
- Drive PPAP submission packages with quality; own the molding-side evidence.
- Triage process drift in production; tighten or restore the window without expanding it past validated limits.
Requirements
What we're looking for
- Five or more years molding precision parts on all-electric presses, ideally optical or medical components.
- Scientific molding training (RJG, AIM Institute, or equivalent) and demonstrated process documentation.
- Fluent in mold-temperature control, cavity-pressure monitoring, and shot-weight discipline.
- Comfortable working alongside an optical-bench evidence loop — birefringence and form take precedence over dimensional pass alone.
Nice to have
Useful, not required
- Direct experience with cyclic olefin polymers (Zeonex, Topas) and optical PMMA grades.
- Vertical-clamp insert-molding experience for optomechanical subassemblies.
More about the role
Context
About the role
Process is where polymer optics succeed or fail. You’ll be the person who decides whether a tool is ready to release to production — and the person who pulls it back when the optical evidence says the window has drifted. You partner with the tooling engineer on every new tool and with the senior quality manager on every PPAP.
How to apply
Send a short note and resume to the address linked above. Tell us one process window you developed where the optical or functional release criteria — not the dimensional — were the binding constraint.
