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 high-performance 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 hyper focus on execution. 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 runs toward hard problems, thrives under pressure, and wants to build something history will remember you for, this role is for you.
