Principal Materials Scientist

Amrize • Fishers, IN

4d • Onsite

About The Position

Serve as the centralized technical authority on fundamental material science, driving the understanding of structure-property relationships to accelerate innovation across all R&D business groups. This role bridges theoretical polymer physics and chemistry with practical formulation, ensuring rapid, data-driven product development from benchtop to commercialization.

Requirements

• PhD in Materials Science, Polymer Chemistry, Physical Chemistry, or a closely related highly technical field.
• 15+ years of progressive, advanced R&D experience in the specialty chemicals, coatings, adhesives, or elastomers industry.
• Deep, proven understanding of multiple polymer chemistries, specifically including solvent-based rubbers, silicones, polyurethanes/polyureas, and epoxies.
• Expert-level proficiency in interpreting data from advanced thermal, rheological, and spectroscopic characterization equipment to build predictive structure-property models.
• Demonstrated ability to lead without direct authority, acting as a high-level technical consultant and mentor to specialized R&D formulation teams.

Responsibilities

• Define and build fundamental structure-property relationships to accelerate new product development across all core business units: Contact Adhesives, Silicon Coatings & Adhesives, Polyurethane & Polyurea Systems, and Epoxy Coatings.
• Translate complex molecular interactions into predictable macroscopic performance metrics (e.g., abrasion resistance, flexibility, adhesion, and weatherability) to reduce formulation trial-and-error.
• Identify synergistic technology platforms and raw materials that can be leveraged across different product lines to capture new market opportunities in roofing, building envelopes, and marine/industrial flooring.
• Lead the strategic use of deep analysis equipment across the development labs to understand exactly why products perform the way they do.
• Utilize advanced characterization tools, including Fourier-Transform Infrared (FTIR) Spectrometers, Gas Chromatographs (GC-MS), Differential Scanning Calorimeters (DSC), and Advanced Rheometers.
• Confirm cure mechanisms, identify trace contaminants, analyze failures, and qualify complex new raw materials using chemical analysis.
• Correlate advanced chemical analysis with mechanical performance testing derived from Universal Testing Machines (UTMs) analyzing stress-strain curves, modulus, and peel/lap shear adhesion.
• Act as the primary technical consultant to specialized R&D Managers/chemists, helping to resolve complex formulation roadblocks involving polymer/crosslinker systems, catalyst packages, and adhesion promoters.
• Partner closely with the Manager of the Pilot Lab & Process Scale-Up to ensure that foundational molecular behaviors and reactive chemistries translate successfully from 1-liter benchtop batches to 20-50kg pilot batches.
• Provide predictive risk analysis for process scale-up by analyzing mixing dynamics, exotherms, and temperature controls for complex reactive chemistries.
• Foster a culture of scientific rigor, continuous learning, and advanced experimental design across the entire R&D organization.
• Ensure all cross-functional development aligns with critical industry standards (e.g., ASTM standards for sealants and roof coatings) and evolving environmental regulations.

Benefits

• Competitive salary
• 401(k) pre-tax and/or Roth after-tax savings
• Employee Stock Purchase Plan
• Medical, Dental, Disability and Life Insurance
