Thea Energy is a fusion technology company working on a stellarator-based approach to delivering carbon-free energy at scale. The company focuses on planar, programmable magnet arrays made with high-temperature superconductors, paired with software controls, to simplify stellarator hardware. Thea Energy’s near-term system is described as “Eos,” positioned as an integrated stellarator neutron-source system to de-risk a future fusion power plant concept (“Helios”). Thea Energy was founded in 2022 as a spin-out connected to Princeton Plasma Physics Laboratory and Princeton University.

Thea Energy lists a headquarters and lab in Kearny, New Jersey, plus an office presence in Princeton, New Jersey. Most open roles and early-career internships are listed as on-site in Kearny, NJ, including internship postings that specify an on-site weekly expectation.

Palpable Score

63
/ 100
Thea Energy is a credible early-career option for students in relevant STEM fields because Thea Energy runs paid spring and summer internships with clearly described technical tracks. Thea Energy is also unusually clear on pay ranges for many roles, including hourly internship pay. The biggest constraints are limited public detail on interview stages and feedback, plus very little published evidence on early-career progression and retention outcomes.
