About Magrathea
Magrathea is reinventing a foundation of modern civilization : secure, clean magnesium metal. Magnesium enables critical sectors - aerospace, defense, automotive, aluminum alloys, titanium production, and advanced manufacturing - yet 95% of global supply comes from coal-based production in China. That's not just a supply chain fragility - it's a national security exposure.
We've developed a first-of-its-kind, electrolytic process to produce magnesium from seawater and brines - unlocking industrial independence and dramatically lowering environmental impact. We are backed by investors behind Tesla and SpaceX, major European industrial families, and the U.S. defense community.
If you've ever wanted to change the trajectory of an industry - this is one of the rare chances.
Is Magrathea for me?
Magrathea is for people who :
- Are builders, not spectators.
- Run toward the hardest problems.
- Want to leave behind infrastructure that reshapes economies.
We are a tight, elite group scaling the first major electrolytic magnesium smelter of the 21st century. You will be hands-on from your first day, making decisions that move from pilot to steel in the ground in Arkansas - and metal poured on the other end. No bureaucracy. No filler work. Every contribution is mission-critical and will be remembered.
What You'll Do
You will be the technical force behind bringing a frontier technology to commercial scale - fast, safely, and elegantly.
You'll be the person everyone counts on because you've done this before and you love doing it again.
What You Bring
Compensation & Benefits
We pay high for talent that raises our ceiling.

If you're looking for the most challenging, consequential, and meaningful engineering work of your career - this is the moment. Help us build the clean industrial base future generations will inherit. Help us restore independence to a security-critical strategic metal. Make history with us.
