Job description

Integrated Modeling Intern - Fall 2026, Kearny, NJ (Technology – Physics /Internship /On-site)

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. Thea Energy's approach to fusion confinement is uniquely positioned to leverage AI and learned surrogates in the design of its fusion power plant. Likewise, the large design space of the stellarator approach makes numerical optimization of figures of merit essential. Thea Energy is looking for a motivated intern with familiarity with toroidal plasma confinement devices to perform several tasks:

• Implement reduced models of physics phenomena and engineering systems
• Generate coupled workflows of integrated models including constrained numerical optimization of designs
• Train surrogate models on high-fidelity simulation outputs

Company Benefits:

• Compensation: $18-25/hr Undergraduate and $26-30/hr Post-graduate

Requirements:

• 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.

Diversity and Inclusion:

Thea Energy is an equal opportunity employer committed to creating a company of diverse backgrounds. By creating a diverse environment, we will bring new ideas and approaches to solving some of the world's hardest (and most important) problems. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, gender, sexual orientation, gender identity or expression, national origin, family or marital status, age, disability, veteran’s status or other characteristic protected by applicable laws and regulations.
