Supply Chain Manager
Operations · Full-time
Posted on Nov 10, 2026
We seek a Supply Chain Manager to develop an international supply chain for a proprietary specialty polymer at the heart of Sepion’s next-generation battery separator technology. Sepion’s materials are being qualified with Tier-1 global EV and energy storage (ESS) companies, and the supply chain this person builds will determine whether we can deliver at mass scale, quality, and cost.
This is a first-of-its-kind supply chain: no one has made and moved this material at commercial scale before. You will secure raw material supply, find and qualify manufacturing partners, negotiate commercial terms, and make sure every link in the chain delivers on spec, on time, and at the right cost.
You will lead vendor sourcing, price negotiation, scoping compliance, supply planning, cost modeling, and managing supplier performance with the Product team and our partners. In your first year, success looks like: a qualified supply chain running from raw materials to finished product; at least two qualified sources for critical materials; and a landed-cost model and supplier cost-down roadmap that support commercial pricing.
Location: San Francisco Bay Area, CA. Expect roughly 30–50% international travel.
