Systems Engineer

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 areas 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-orientated corporate culture to lead the company in our expansion. We are seeking people who:

• 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 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:

The Systems Engineer, reporting to the Systems Engineering Manager, is primarily responsible for the development, integration, and coordination of systems-level engineering activities for Terrestrial Energy’s IMSR technology. This role applies systems engineering principles to support requirements management, interface coordination, system architecture development, and verification planning across multidisciplinary engineering teams. The successful candidate will contribute to the advancement of IMSR reactor systems through the application of structured systems engineering methodologies in a highly regulated nuclear technology environment.

• Develop, maintain, and manage system requirements for IMSR systems and subsystems in coordination with design engineering, safety, and licensing teams.
• Perform requirements decomposition, allocation, and traceability across system, subsystem, and component levels.
• Develop and maintain system descriptions, functional breakdowns, and system architecture documentation.
• Identify, document, and track system assumptions, constraints, and design decisions throughout the engineering lifecycle.
• Support configuration management activities and conduct change impact assessments from a systems perspective.

• Identify and document interfaces between engineering disciplines (mechanical, electrical, I&C, safety, licensing) and between systems and subsystems.
• Develop and maintain Interface Control Documents (ICDs) and interface registers to manage system integration.
• Facilitate cross-functional technical coordination meetings and manage follow-up on interface issues and action items.
• Identify, assess, and track integration risks and dependencies across systems and subsystems.

• Develop and maintain requirements verification matrices linking requirements to verification methods.
• Define verification methods (analysis, inspection, test, demonstration) for system requirements in accordance with the V-model approach.
• Coordinate verification planning activities across engineering disciplines and support the organization of verification evidence.
• Support validation planning to ensure system-level performance meets…
