Senior Materials Engineer, Polymer Additive Manufacturing

We are looking for a Senior Materials Engineer to own the actual atoms to be programmed. This is a hands‑on frontier engineering role spanning polymer chemistry, compounding, characterization, process development, and production validation. Specifically, you will: Lead the full cycle development of new foam compounds across TPU, PEBA, and adjacent systems. Design formulations, run material production trials, test materials in our production cells, build process windows for foaming, deposition, and bonding inside the production cells. Develop advanced additive manufacturing processes for low-density thermoplastic elastomer foams. Own material characterization workflows, including rheology, thermal analysis (DSC, TGA), density, morphology, degradation and stability, and mechanical testing (tensile/compression, energy return, hysteresis, and durability metrics). Source and evaluate raw materials, additives, blowing agents, and processing aids. Work hands‑on with compounding lines and external/internal production setups to optimize throughput, consistency, and foam quality. Oversee material manufacturing and scale‑up, from experimental batches to robust repeatable production. BS or MS in Materials Science, Chemical Engineering, Plastics Engineering, or equivalent. A minimum of 3 years of industry experience focusing on the applications of polymers in product development, including proven experience developing new polymer formulations or processes. Deep understanding of physics governing in-process and post-process polymer behavior: thermodynamics, mechanics of extrusion/deposition, polymer rheology, crystallization/viscoelasticity, etc. Strong analytical and problem‑solving skills, with the ability to apply engineering principles to novel applications and to troubleshoot materials‑related challenges in design and production settings. Familiarity with mechanical testing, data‑driven process development and statistical process control. Experience with polymer additive manufacturing. You’re a high‑agency operator with mission‑critical discipline and accountability. You identify and neutralize threats before they elevate. #J-18808-Ljbffr Elastium Inc
