R&D Thermal Hydraulics Technical Lead

Interested in helping us transform thermal and electric energy? Become a part of the leading Generation-IV nuclear plant development team. Come join us at Terrestrial Energy, a US developer of advanced, Generation IV nuclear reactors. We are growing our workforce to develop and deploy our Integral Molten Salt Reactor (IMSR) small modular nuclear plant to provide cost‑competitive, clean firm heat and power to industry.

The Company has recently completed a merger creating a publicly listed operating company (NASDAQ “IMSR”) to secure the capital resources for our next growth phase. With the current alignment of US Federal and State government, as well as industry interest in Small Modular Reactor (SMR) and advanced reactor technologies such as Terrestrial Energy’s IMSR, there is today a unique and compelling opportunity to participate in the execution of the company’s growth business plan.

The Company is building a team of high‑performing business professionals and leaders in engineering, R&D, product management and business development at our Charlotte, North Carolina headquarters and future project sites. We are looking for talented individuals who can help build the organization, processes, and goal‑oriented corporate culture to lead the company in our expansion.

• Have US market experience and perspectives bringing good judgement and innovative approaches to problem solving and business plan execution.
• Have demonstrated exceptional performance in past engineering projects.
• Offer exceptional leadership and team‑building capabilities.
• Have a deep understanding of the requirements for advanced reactor development.
• Can assist in the creation of the discipline and organized company structure, and contribute to a culture of excellence, necessary for the development and deployment of the Company’s IMSR plant.
• Can thrive in a fast‑growing and opportunity business environment, and are capable of flexibility and adaptability at a time of organizational change.
• Have the specific skillset and experience for the following role:
