About this role
About Thea Energy:
Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.
Position Overview:
As Director - Diagnostics, you will lead the strategy, design, implementation, and operation of the plasma diagnostic suite for Thea Energy’s flagship fusion systems. In our planar coil stellarator architecture, real-time data is at the core of our dynamic control systems and AI digital twins. You will build and lead a world-class team of physicists and engineers tasked with measuring critical plasma parameters (temperature, density, confinement, magnetic topology, and impurities) to validate our physics models and feed our automated control loops.
This is a high-impact, leadership-level role requiring deep technical expertise in magnetic confinement fusion instrumentation, excellent team-building capabilities, and a collaborative mindset to interface with our magnet, materials, and AI software teams.
