Battery Cell Prototyping Engineer

About the Role

TaiSan is developing next-generation polymer electrolyte to enable Sodium Batteries 2.0 — higher energy density, safer, and scalable. We are looking to recruit Battery Cell Prototyping Engineer to assemble and optimize multilayer pouch cells that validate our Gen 1-3 technology roadmap. In this role, you will be responsible for translating materials innovation (electrolyte, electrodes, polymer systems) into working pouch and cylindrical cells. You will work closely with electrolyte, polymer, and electrode teams to improve performance metrics and move toward semi-automated assembly workflows. Your work will directly impact energy density, cyclability, safety validation, and readiness for pilot-scale production.
