Systems Engineer

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 U.S. federal and state government, as well as industry interest in 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.

• 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 stakeholder needs and mission objectives.

• Prepare technical documentation including system summaries, requirements specifications, design decision records, and traceability reports.
• Develop figures, block diagrams, functional flow diagrams, and presentation materials for design reviews and stakeholder communications.
• Maintain organized technical records within document control and configuration management systems in compliance with quality requirements.
• Support the preparation of engineering reports, technical memoranda, and regulatory submissions requiring systems‑level analysis.

• Work closely with Systems Engineering, Design Engineering, Safety, Licensing, and Project Management teams to ensure integrated system development.
• Participate in design reviews, technical assessments, and cross‑functional working groups to provide systems engineering perspectives.
• Interface with engineers across multiple disciplines to coordinate system‑level decisions and ensure alignment with project objectives.
• Contribute to the continuous improvement of systems engineering tools, processes, and best practices.
