FREQUENTLY ASKED QUESTIONS
What types of nuclear jobs are listed on smrintel.com?
smrintel.com aggregates open positions across the entire small modular reactor industry — reactor physics, thermal hydraulics, nuclear safety and licensing, health physics, radiation protection, mechanical and electrical engineering, HALEU fuel cycle, NRC regulatory affairs, construction management, and nuclear operations. Roles span from entry-level to VP-level across 40+ companies including TerraPower, Kairos Power, Oklo, Aalo Atomics, X-energy, Radiant, and Centrus.
How often are nuclear job listings updated?
Job listings are refreshed every time the smrintel.com agent runs (twice daily). We aggregate from Greenhouse, Lever, and Ashby applicant tracking systems used by leading nuclear companies, plus Indeed RSS for broader coverage. New postings typically appear within 12 hours of being published.
Which companies are hiring the most in the SMR industry?
As of May 2026, the most active SMR hirers include TerraPower (building Natrium in Wyoming), Kairos Power (constructing Hermes in Tennessee), Oklo (Aurora reactor at INL), Aalo Atomics (targeting 2026 criticality), and X-energy (Xe-100 for Dow). Fuel cycle companies like Centrus and BWXT are also scaling up for HALEU and TRISO production.
Are there remote nuclear engineering jobs?
Yes — many nuclear companies offer remote or hybrid positions, particularly in software engineering, NRC licensing, nuclear safety analysis, project management, and business development. Roles requiring reactor access or laboratory work are typically on-site at locations like Idaho National Laboratory, Oak Ridge, or company headquarters.
How do I get started in the nuclear SMR industry?
The SMR industry is hiring across disciplines. Nuclear engineering degrees are valued but not always required — mechanical, electrical, chemical, and materials engineers are in high demand. Companies like TerraPower, Kairos, and Aalo are also hiring software engineers, data scientists, and project managers. Check the listings below and filter by department to find roles matching your background.
