Rheology Scientist

The RoleYou will lead the design, execution, and analysis of rheological experiments to build a practical, decision-oriented understanding of how our polymer materials behave in real processing environments. This is not academic exploration, this role is focused on answering how and why our materials perform the way they do, and using that understanding to guide formulation, processing, and product decisions.This role sits within a collaborative materials development team and reports to our Associate Director of Product Development. While highly autonomous in day-to-day work, you will partner closely with chemists, process engineers, and materials scientists to connect formulation, processing, and performance.Success in this role means not just generating high-quality data, but using it to define process windows, guide formulation decisions, and ensure our materials perform reliably in real-world applications.What You’ll DoDesign and execute rheological experiments to characterize polymer systems under a variety of extrusion based methods.Apply standard rheological techniques while developing and adapting methods for new materials and equipmentEstablish processing > structure >property relationships that inform product performanceDefine operating windows and process boundaries to ensure materials meet target specificationsPartner with chemists to answer key formulation questions (e.g., catalyst loading, mixing behavior, residence time effects)Build structured, reproducible experimental workflows with a strong emphasis on rigor and data qualitySynthesize and communicate results clearly to enable fast, confident decision-making across the teamSuccess in This Role (First 6 Months)Establish rheological guidelines for a core additive manufacturing productDefine process windows and constraints required to achieve consistent performanceProvide clear recommendations on formulation and processing variables (e.g., catalyst incorporation, mixing conditions)Build a foundation of reliable, interpretable data that informs both current products and development of future productsWho You AreStrong foundation in rheology applied to polymer or soft material systemsHands-on experimentalist who can design as well as execute studiesComfortable operating with autonomy and bringing structure to ambiguous problemsProduct-oriented thinker who connects material behavior to real-world performanceClear and concise communicator who can translate complex data into actionable insightsPragmatic and outcome driven. You prioritize solving the right problems over exploring everythingQualificationsRequired:MS or PhD in Polymer Science, Materials Science, Chemical Engineering, or a related fieldMeaningful experience with thermomechanical analysis methods, e.g. DMA, DSC, TGA, TMAHands-on experience with rheological characterization of polymeric materials (e.g., melts, resins, gels, or similar systems)Experience designing experiments and interpreting results in a processing or application contextPreferredIndustry experience in additive manufacturing, polymers, coatings, or advanced materialsExperience working with or supporting filament-based AM processesExperience working with singly or twin screw extrusion based processesExperience developing or adapting rheological methods for new materials or equipment
