Interested in helping us transform thermal and electric energy? Become a part of the leading Generation‑IV nuclear plant development team.Terrestrial Energy is developing for near‑term commercial operation, a zero‑emissions cogeneration plant using its proprietary Integral Molten Salt Reactor (IMSR) technology in an innovative, small and modular plant design.Safety ManagerUnder the direction of the Engineering Director, the Safety Manager is primarily responsible for leading and building our safety analysis team, establishing and growing a world‑class safety analysis organization while managing all aspects of safety analysis and supporting regulatory compliance and licensing activities for the development and deployment of our IMSR technology.The successful candidate will recruit, develop, and lead a team of safety engineers and analysts, collaborate closely with the design and licensing teams, and ensure the safety case for our advanced reactor design meets all regulatory requirements and demonstrates the inherent safety features of our technology.Leadership and Team ManagementLead, mentor, and develop a team of Safety Analysis Engineers, Safety Analysts, and SpecialistsEstablish team priorities, allocate resources, and manage workload across multiple projectsConduct performance evaluations and support professional development of team membersFoster a culture of technical excellence, safety consciousness, and
