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 contributed 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:

The Salt Qualification Scientist/Engineer, under the direction of the R&D Director, is primarily responsible for leading the experimental testing and qualification of salts for Integral Molten Salt Reactor (IMSR) applications. This role will focus on designing and implementing rigorous test programs, conducting hands-on laboratory experiments, and performing detailed data analysis to characterize the properties and behavior of salts used in the reactor. The position requires strong experimental and materials testing expertise combined with hands-on laboratory experience, along with the ability to prepare technical documentation to support reactor licensing and operational needs.

Within this role responsibilities include:

• Design and implement experimental programs to characterize molten salt properties for IMSR applications, with a focus on material testing, chemical analysis, and long-term performance under reactor conditions
• Develop and execute test procedures for thermophysical, chemical, and performance measurements that meet reactor specifications and provide reliable data for reactor qualification
• Conduct laboratory experiments to measure critical salt properties, including thermal stability, chemical reactivity, corrosion resistance, and long-term performance. Operate experimental equipment and ensure compliance with safety standards
• Analyze experimental data using statistical tools (e.g., JMP, MATLAB, Python), including uncertainty quantification, regression analysis, and data validation. Develop models and correlations to support salt qualification and performance predictions
• Oversee quality control for all testing activities, ensuring proper documentation, traceability, and compliance with regulatory requirements (e.g., NRC, DOE). Maintain laboratory safety standards in line with Good Laboratory Practices (GLP)
• Prepare technical reports and qualification documents to support regulatory submissions, including responses to NRC inquiries. Present findings to regulatory bodies during audits and meetings
• Work closely with reactor design engineers to align test programs with reactor specifications. Collaborate with materials engineers, chemistry teams, and other technical teams to support corrosion, compatibility, and performance studies
• Continuously evaluate and improve test methods, experimental setups, and data analysis techniques to enhance the efficiency and accuracy of salt testing programs
• Support procurement and vendor qualification processes for salt materials and related supplies
• Manage testing schedules, resources, and priorities to meet project milestones. Provide regular updates to the R&D Director and project teams
• Provide technical guidance to junior scientists or engineers, assisting with testing and characterization activities
• Present experimental results and testing approaches to internal teams, external stakeholders, and regulatory agencies
