About The Position

Shape the Future of Food & Beverage Packaging. Are you passionate about polymers and driven to push materials beyond today’s limits? Join our Materials Innovation team as a Staff Engineer, where you’ll play a critical technical leadership role advancing polypropylene (PP) and related polymers that redefine performance, sustainability, and manufacturability in food and beverage packaging. This is a high-visibility, high-impact role for a seasoned polymer expert who thrives at the intersection of materials science, manufacturing, and business outcomes. You’ll own innovation from raw material selection and structure–property–function relationships through processing, manufacturing, and end-use performance, with a strong focus on in‑line thermoforming (post‑trim and trim‑in‑place) and injection molding. Your influence will extend across cup, lid, and container platforms spanning PP, PET, and polystyrene, while collaborating on hybrid solutions involving paper substrates and molded fiber. If you want your expertise to translate into commercialized solutions, competitive advantage, and measurable results, this role was built for you.
