Physics Intern - Fall 2026

Thea Energy•Kearny, NJ

9d•$18 - $30•Onsite

About The Position

Thea Energy is seeking motivated interns to work with their physics team on projects relevant to stellarator optimization, toroidal plasma confinement, plasma divertor and edge physics, plasma-materials interactions, and fusion neutronics. Interns will take ownership of a dedicated research project under the guidance of a senior physicist mentor, conduct literature reviews, run simulations or analyze data to inform Thea Energy's stellarator design, and collaborate with mechanical and electrical engineers. They will also support engineering design reviews by translating physics modeling and simulation results into specifications, utilize project management tools, and present their findings at the conclusion of the internship.

Requirements

Candidates may be pursuing undergraduate, masters, or PhD degrees.
Ability to occasionally lift up to 50 lbs.
Ability to perform activities such as typing, standing, or sitting for extended periods of time.
Ability to work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, high voltage, high current, pressure systems, and cryogenics.
