Interested in helping us transform thermal and electric energy Become a part of the leading Generation-IV nuclear plant development team. This position is remote until the office opens in or around Bryan, TX on or before December 2025, after which time it will be a 100% on site role. Terrestrial Energy is developing for near-term commercial operation, a zero-emissions cogeneration plant for a global industry using its proprietary Integral Molten Salt Reactor (IMSR) fission technology in an innovative, small and modular plant design. Over the last 5 years, the Company has recognized the exceptional and unmatched opportunities in US markets created by the policies of the US Federal and States governments, and by the actions of the US industrial private sector, including its world leading IT sector developing AI commercial product. The Company recognizes that its path to business success and likely sole path to success, is to wholly align with the US market as a US company, and effect all the organizational changes necessary to achieve this alignment.
