Chief of Staff

About Magrathea Based in Oakland, California, Magrathea is a global category leader in critical mineral production technology. Our mission is to rebuild the magnesium metal supply base, delivering secure access to one of the most critical materials on Earth. Magnesium is essential to the aluminum, steel, titanium, nuclear, defense, and aerospace industries, but 95% of global supply comes from China where large amounts of coal are used to make metal. This isn't just an economic risk: it's a national security threat, and Magrathea is fixing it. We've developed a next-generation electrolytic process to make magnesium metal from seawater and brines, unlocking a new path to industrial independence and to a cleaner environment for future generations. We're backed by the earliest believers in Tesla and SpaceX, major European industrial families, and the U.S. Department of Defense. If you're ready to make a lasting real-world impact, let's talk. Is Magrathea For Me? You'll be joining a small, high-trust team of builders on a mission to stand up the first major electrolytic magnesium smelter this century. We’re doing it this decade. There are no pointless positions here, no layers of middle management, no meetings about meetings: just a deep focus on moving important work forward. You'll be hands-on from day one, shaping the core of a technology that will have major impacts on national security, clean technology, and industrial resilience. If you're the kind of person who is energized by hard, consequential problems, stays clear, calm, and effective when the work is ambiguous or urgent, and wants to build something that will matter far beyond the company, this role is for you. What This Role Is - And Is Not This is a hands-on execution role. The highest-leverage person in this seat will personally drive critical workstreams, unblock details, chase vendors, build operating systems, prepare materials, walk the floor, write follow-ups, own deadlines, and make sure important things actually happen. You should be excited by a role where you are willing to do whatever useful work moves the mission forward. One day you may be helping prepare for a board meeting or government funding process; the next you may be calling vendors, tightening a project plan, improving a safety process, resolving an operational bottleneck, or sitting with engineers to turn a messy problem into a clear next step. This role is for someone who wants to build, not observe. Operate, not advise.
