What is a small modular reactor?

A Small Modular Reactor (SMR) job involves working on the design, development, construction, operation, or regulation of SMRs, which are advanced nuclear reactors that are smaller and more flexible than traditional nuclear plants. Professionals in this field may include engineers, scientists, safety analysts, project managers, and regulatory specialists. These roles focus on improving reactor efficiency, ensuring safety, and advancing clean energy solutions. SMR jobs exist in government agencies, private companies, and research institutions working to develop next-generation nuclear technology.

What are some typical daily responsibilities for a small modular reactor engineer?

As a Small Modular Reactor Engineer, your daily tasks might include performing system analyses, monitoring reactor performance, reviewing safety protocols, and collaborating with other engineering disciplines to troubleshoot technical challenges. You may also be involved in preparing regulatory reports, overseeing construction or installation activities, and participating in design reviews or risk assessments. Working closely with project managers, safety specialists, and government regulators is common to ensure all reactor operations meet stringent safety and quality standards. This role offers a dynamic and collaborative work environment, with frequent opportunities to apply technical expertise to innovative, real-world energy solutions.

What are the key skills and qualifications needed to thrive in the small modular reactor position, and why are they important?

To excel in a Small Modular Reactor Engineer role, candidates need a solid background in nuclear engineering, mechanical or electrical engineering, and strong analytical abilities, often supported by a relevant bachelor's or master's degree. Familiarity with nuclear reactor simulation software, regulatory compliance tools, and safety certification (such as a Professional Engineer license or NRC qualification) is highly valued. Effective communication, teamwork, and problem-solving skills are key for coordinating with multidisciplinary teams and ensuring regulatory standards are met. These qualifications are crucial to designing, operating, and maintaining advanced nuclear systems safely and efficiently within a regulated environment.

Job description

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 Mechanical Engineer/Analyst - Model Development, under the direction the Mechanical Engineering Manager, is primarily responsible for contributing to the design and analysis of IMSR reactor systems, components and materials through the Detailed Engineering phase.
In particular, the role will include developing and implementing custom Engineering models for predicting the behavior and integrity of reactor materials, components, and systems throughout their operating life under IMSR reactor environmental conditions.
Other responsibilities include:
  • Conducting literature and operating experience (OPEX) reviews to support design and model development
  • Collaborating with the Research and Development (R&D) group to translate experimental results into custom Engineering models of components and materials under reactor conditions and to plan new experiments as needed
  • Preparing models, calculations and reports for analysis of reactor components (such as graphite core components, core support structures, the reactor vessel, and other in-core components) including evaluating the effects of irradiation, fatigue, creep, dynamic and static mechanical and thermal loads, and other aspects as needed
  • Developing computer codes for building custom analysis tools, automating input/output processing and customizing functionality of commercial software
  • Attending and participating in conferences and industry events to stay familiar with and contribute to the development of current codes, standards, and industry best practices
  • Interface with external experts and regulatory agencies
