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 developing an electrolytic magnesium production demonstration plant in the Salt Lake City Area. You will be the person who builds the team and runs it. The facility will produce magnesium metal and the reliable operating data needed to validate the process and inform future commercial project development. You'll be hands-on from day one, on the ground and shaping the facility from detailed engineering drawings through construction, startup, and demonstration operations. 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 Involves This is a hands-on build-and-operate role, with responsibility for a demonstration plant where disciplined operating campaigns and reliable data are central to success. You'll help design the facility, get it built, bring it to life, and then run it. You'll review P&IDs and 3D models with engineers, walk the site with our host-site partner and contractors, chase long-lead equipment, write the operating procedures, lead commissioning and startup, and then own day-to-day production, safety, cost, quality, and operating data. One day you may be flagging an operability problem before it gets built into steel; the next you may be leveling a skid, resolving a permitting question with regulators, or training the first operators we hire. This role is for someone who wants to build a plant, not inherit one. Operate, not observe.
