Supply Chain Manager

Sepion Technologies is bringing a new class of battery separator coating to market. Born at Lawrence Berkeley National Laboratory, our nanoscale polymer coatings improve the cycle life, energy density, and safety of lithium-ion batteries, run on the same gigafactory equipment used today, and are priced to win in the largest battery markets in the world. Our products are in qualification with several of the biggest EV, energy storage, and consumer electronics companies, and we have signed a commercial agreement with a global separator leader to scale from production trials to high-volume manufacturing. Commercial volumes begin in 2027. We don’t build factories. We grow through a network of chemical producers, coating partners, and separator makers across North America, Europe, and Asia, which lets us scale fast without heavy capital. Sepion is a Series B-funded company backed by Fine Structure Ventures, W. L. Gore & Associates, and Syensqo. We are united by a passion to sustainably power humankind. Joining our team means committing to a psychologically safe workplace where diversity, creative thinking, transparency, and compassionate feedback thrive, at the moment a startup becomes a global supplier.
