ILRubber Materials Engineer – Product Development / Molding
Listed pay for BS-level Product Development roles on Crosslinked center on $119k (192 with a salary).This posting does not list one.
Develop rubber/polymer formulations and drive new products from concept through commercialization and molding.
Worth knowing
Why it is interesting. Own projects end to end—formulation, prototyping, pilot runs, and commercialization—with hands-on FTIR, DMA, DSC, TGA, and tensile testing.
Might not be for you. Requires 3+ years of hands-on rubber formulation and molding experience; not an entry-level or non-rubber materials role.
