ElectrodeProcessEngineer

Who We Are Factorial Energy is a pioneering U.S.-based solid-state battery company driving the future of energy storage and electrification. Partnered with global leaders including Mercedes-Benz, Stellantis, Hyundai, and Kia, Factorial is at the forefront of developing next-generation e-mobility platforms for commercial, defense, and consumer applications—spanning electric vehicles (EVs), drones, eVTOL aircraft, power tools, marine systems, robotics, and more. The company has achieved multiple industry firsts, including being the first to power a demonstration vehicle with a global OEM (Mercedes- Benz) which achieved over 1,200 km (749 mi) of range, and the first to earn UN 38.3 certification for automotive-sized lithium-metal solid-state cells, the first to deliver B-samples of automotive-sized solid-state batteries to major OEMs. The Opportunity: Factorial Energy is seeking an Electrode Process Engineer to join our team in our Cheonan, South Korea location. This person will be responsible for the development, optimization, and scale-up of anode and cathode electrode manufacturing processes for our Silicon Power Cell line, owning the full electrode process chain from slurry mixing and coating through calendaring and slitting. The ideal candidate brings deep hands-on expertise in wet electrode processes and slurry rheology and is comfortable translating lab-scale breakthroughs into scalable, high-yield manufacturing processes in a fast-moving environment. In this role, you will: Lead development and optimization of anode and cathode electrode processes for Si-based power cells, including slurry mixing, slot-die coating, drying, calendaring, and slitting Define and maintain process windows for slurry rheology, coating weight, thickness uniformity, calendaring density, and adhesion strength Establish and maintain SOPs, PFMEA, and Control Plans for all electrode process steps, defining CTQs and process parameters Develop electrode formulation strategies to accommodate
