Responsibilities Lead the development for adhesives, seals, potting, and thermal interface materials (TIMs) for high‑performance battery packs. Leverage your deep chemistry expertise to develop novel formulations while benchmarking market‑leading solutions. Identify material opportunity by establishing key metrics, such as cost, performance, reliability, and safety. Conduct hands‑on characterization (DSC, TGA, DMA) to identify failure modes and optimize adhesion, sealing, dielectric, and thermal performance. Collaborate closely with cross‑functional teams specializing in module and pack design, simulation, manufacturing, and Supply Chain to balance performance, cost, reliability, and safety. Document data and analysis clearly and make presentations to communicate findings to stakeholders and leadership. Qualifications BS with 5+ years, MS with 3+ years, or a fresh PhD in Chemistry, Materials Science, or Chemical Engineering with a focus on polymer chemistry. Experienced in polymer formulation/chemistry of acrylics, polyurethanes, silicones, and epoxies with strong knowledge of the interplay between polymer backbones, chain length, and mechanical/thermal/environmental functionality. Proven ability to quantify adhesive joint integrity, CTE matching, flame retardancy, and environmental performance. Proficient in a wide array of characterization techniques such as DSC, TGA, DMA, rheometry, FTIR, and Instron. Strong project planning and execution skills, with the ability to define clear objectives, break down complex tasks, and establish realistic timelines for successful project delivery. Effective communication skills, with the ability to summarize and present insights from large datasets clearly and concisely. Availability to travel up to 25% to collaborate with material suppliers and internal manufacturing sites, ensuring seamless technology transfer from the R&D lab to high‑volume production.
