Thea Energy Tech Stack

Stellarator fusion reactor design and commercialization

Renewable Energy Power Generation Kearny, New Jersey 51–200 employees Founded 2022 Privately Held

Thea Energy is designing and building the Eos stellarator, a magnetic fusion system architected around mass-manufacturable planar coils and real-time software controls. The tech stack—Python, MATLAB, COMSOL, Fortran, C++, plus power systems tools (ETAP, DIgSILENT, PSCAD)—reflects a hybrid physics-simulation and industrial-controls operation. Active hiring is concentrated in engineering roles (18 open, mostly senior and director level), signaling transition from research prototyping toward integrated system assembly and commissioning.

About Thea Energy

Thea Energy develops commercially viable fusion energy systems based on stellarator magnetic confinement. Founded in 2022 as a Princeton Plasma Physics Laboratory and Princeton University spin-out, the company is advancing a design originally invented at Princeton. The primary product in development is Eos, an integrated stellarator that uses planar coil magnetic arrays and dynamic software controls to achieve steady-state fusion neutron production. The 51–200 person team is headquartered in Kearny, New Jersey and operates across engineering, research, operations, and manufacturing support functions. Current focus areas include Eos commissioning, plasma-facing component operational planning, and assembly-sequence optimization.
