Advanced Materials Engineer, Global Materials Science

Join Amazon's Global Materials Science (GMS) organization as we build the future of sustainable e-commerce packaging – from the paper machine through the converting line and into our global fulfillment network. As an Advanced Materials Engineer, you'll bring deep paper manufacturing, converting process, and equipment engineering expertise to drive materials innovation at scale. This is a hands‑on, technically rigorous role where you'll work directly with paper mills, converters, and equipment OEMs to develop, optimize, and scale kraft and extensible kraft paper grades and paper-based packaging formats. You'll bridge the gap between raw material production, machine design, converting operations, and Amazon's packaging performance requirements – turning process and equipment knowledge into breakthrough materials solutions. Key job responsibilities Paper Manufacturing Process Expertise: Apply deep knowledge of paper formation, wet end chemistry, pressing, drying, calendering, and rewinding to develop and optimize kraft paper grades for e-commerce packaging applications. Evaluate and improve basis weight, moisture profiles, and roll quality attributes in partnership with paper mill suppliers. Understand and leverage how unit operations at the paper mill level impact downstream paper properties — tensile, stretch, tear, stiffness, porosity, and surface characteristics. Support development and qualification of extensible kraft paper grades, including understanding of processes such as compaction, micro‑creping, and related technologies that impart extensibility. Paper Converting & Packaging Manufacturing: Drive paper bag converting process development and optimization — including adhesive application, folding, gluing, label application, printing, and finishing operations. Evaluate how paper properties interact with converting equipment and processes to influence final package quality, runnability, and yield. Understand and troubleshoot converting line performance issues at the intersection of material properties and machine design — adhesive bond strength, ink adhesion, fold crack resistance, dimensional stability, and web handling behavior. Understand unit operations within paper bag converting — rewetting, drying, folding, creasing, gluing, rewinding — and how machine parameters at each stage affect final product quality. Understand vertical and horizontal bag formation processes and the material property requirements unique to each — including how paper stiffness, stretch, coefficient of friction, and grain direction influence bag geometry, seal integrity, and line speed. Collaborate with converting partners to optimize machine settings, reduce waste, and improve throughput for paper mailer and bag formats. Equipment & Machine Design: Evaluate, specify, and help develop converting and paper processing equipment — including bag machines, folders, gluers, coaters, slitters, rewinders, and web handling systems. Apply mechanical engineering principles to understand how machine geometry, nip pressures, tensions, speeds, temperature zones, and dwell times affect material behavior and product quality. Collaborate with equipment OEMs and internal engineering teams on machine design, modification, and capability upgrades to process new paper grades and packaging formats. Develop equipment specifications and acceptance criteria for new converting machinery, including defining process windows and material‑machine interaction requirements. Understand and optimize tension control, web guiding, and web tracking systems across converting and rewinding operations — ensuring consistent material feed, alignment, and registration throughout the converting process. Evaluate bag formation machinery for both vertical form‑fill‑seal (VFFS) and horizontal converting configurations — understanding how machine design choices impact bag quality, material utilization, and throughput. Troubleshoot mechanical and process issues on converting lines — diagnosing whether root cause is material, machine, or process-related and driving solutions across all three. Support design reviews for new or modified converting equipment, providing materials and process perspective to ensure machines are designed for the target material properties. Coatings, Adhesives & Web Processing: Lead development and qualification of coating and adhesive systems for paper packaging applications — including barrier coatings, heat‑seal coatings, water‑based adhesives, and hot‑melt adhesives. Evaluate coating weight, uniformity, adhesion, and functional performance across substrates and converting conditions. Work with coating and adhesive suppliers to optimize formulations and application processes for manufacturing scale. Understand rewetting, moisture conditioning, and drying operations as they relate to coating application, adhesive activation, and paper dimensional stability during converting. Capital Projects & Piloting: Conduct techno‑economic analysis on capital projects related to paper manufacturing, converting equipment, and process technology investments. Lead piloting activities — from trial planning and execution at supplier facilities through data analysis and go/no‑go recommendations. Support equipment installation, commissioning, and startup for new converting and process technology deployments. Manage contractor relationships and coordinate technical workstreams during capital project execution. Participate in equipment design reviews, factory acceptance testing (FAT), and site acceptance testing (SAT) for new converting and process machinery. Specifications & Quality: Define paper and converting material specifications based on critical performance thresholds required for packaging to protect products and survive the fulfillment network. Translate operational requirements into measurable material properties and acceptable ranges at both the paper mill and converter level. Develop quality control protocols and incoming material testing methodologies to ensure supplier compliance with specifications. Supplier & Manufacturing Collaboration: Work directly with paper mills, converters, coating applicators, adhesive manufacturers, and equipment OEMs to develop and scale new materials, processes, and machinery. Conduct technical evaluations of supplier manufacturing capabilities, process controls, and quality systems. Guide suppliers on process optimization to achieve target material properties, consistency, and yield. Serve as the technical liaison between Amazon and its paper supply chain — translating Amazon's packaging requirements into actionable process and material targets for suppliers. Cross-Functional Partnership: Collaborate with Packaging Engineering on materials-design integration and automation equipment compatibility. Partner with Global Procurement on strategic sourcing, supplier selection, and commercial negotiations. Support sustainability initiatives including carbon footprint reduction, recyclability, and responsible fiber sourcing. Provide technical expertise to program managers, product teams, and deployment teams. Communicate complex materials science and process engineering concepts clearly to technical and non‑technical audiences. Documentation & Knowledge Sharing: Author technical reports, trial summaries, specifications documents, and process development reports.

Contribute to intellectual property generation through public disclosures and patent applications. Mentor junior engineers and technicians on paper science, process engineering, and materials testing methodologies. A day in the life You start your morning reviewing overnight data from a paper mill trial — a new kraft grade designed for extensibility that your team has been developing with the supplier for months. The basis weight and moisture profiles are dialing in, but the calender settings need adjustment to hit the target smoothness without sacrificing stretch. You draft detailed feedback for the mill's process engineers and schedule a call to walk through the data together. By midday, you're on-site at a converting partner evaluating a new paper bag line. The adhesive application window is tight, and you're troubleshooting a bond strength issue tied to paper surface energy. Your experience on the mill side tells you this is a calendering interaction — you suggest a surface treatment adjustment and design a quick trial matrix to validate it. After lunch, you're reviewing mechanical drawings for a new converting line with the equipment OEM. The folding geometry needs adjustment to handle a heavier basis weight kraft, and the glue application nozzles need repositioning for the new bag format. You mark up the drawings and jump on a call with the OEM's design team to walk through the changes — this is where your machine design instincts meet your materials knowledge. Late afternoon, you shift to a techno‑economic model for a capital project — a new offline process technology that could produce extensible-like properties from standard kraft. You're pulling together equipment costs, operating assumptions, and projected material savings to build the business case for leadership. Your day ends with a cross-functional sync where you're bridging the gap between procurement's supplier negotiations, engineering's packaging performance requirements, and the mill's process constraints. You're the person who speaks all three languages — materials, machines, and business. This role is for someone who's spent time on the manufacturing floor — who knows what a wet end looks like at 3 AM during a grade change, and who can translate that experience into materials innovation at Amazon's scale.
