Salt Qualification Scientist​/Engineer

Salt Qualification Scientist/Engineer

Join to apply for the Salt Qualification Scientist/Engineer role at Terrestrial Energy
. The position is remote until the office opens in or around Bryan, TX on or before February 2026, after which time it will be a 100% on-site role.

Terrestrial Energy is developing a zero‑emissions cogeneration plant using its proprietary Integral Molten Salt Reactor (IMSR) fission technology in an innovative, small and modular plant design. The company has recently relocated to the US and is expanding its U.S. team.

• Design and implement experimental programs to characterize molten salt properties for IMSR applications.
• Develop and execute test procedures for thermophysical, chemical, and performance measurements that meet reactor specifications.
• Conduct laboratory experiments to measure critical salt properties including thermal stability, chemical reactivity, corrosion resistance, and long‑term performance.
• Analyze experimental data using statistical tools (e.g., JMP, MATLAB, Python), including uncertainty quantification, regression, and data validation.
• Oversee quality control for all testing activities, ensuring proper documentation, traceability, and compliance with regulatory requirements.
• Prepare technical reports and qualification documents to support regulatory submissions, including responses to NRC inquiries.
• Collaborate with reactor design engineers, materials engineers, and chemistry teams to align test programs with reactor specifications.
• Continuously evaluate and improve test methods, experimental setups, and data analysis techniques.
• Support procurement and vendor qualification processes for salt materials and related supplies.
• Manage testing schedules, resources, and priorities to meet project milestones.
• Provide technical guidance to junior scientists or engineers.
• Present experimental results and testing approaches to internal teams, external stakeholders, and regulatory agencies.

• Expertise in experimental design, data collection, and statistical analysis (e.g., regression, uncertainty quantification).
• Proficiency with data analysis tools (e.g., JMP, Python, MATLAB) for analyzing complex experimental data and developing models.
• Hands‑on experience with thermophysical, chemical, and performance measurements of materials.
• Knowledge of high‑temperature experimental techniques, analytical chemistry, and data acquisition systems (e.g., LIMS).
• Familiarity with laboratory safety, chemical handling, and Good Laboratory Practices (GLP).
• Understanding of nuclear quality assurance and experience preparing regulatory documentation (e.g., NRC, DOE).
• Experience preparing qualification reports and technical documentation for regulatory submissions.
• Proven ability to manage experimental programs, scheduling, and resource allocation.
• Strong technical writing skills for scientific reports and regulatory documents.
• Ability to present technical data to internal teams, external stakeholders, and regulators.
• Experience working collaboratively with multidisciplinary teams.
• Ability to mentor junior staff in experimental techniques, data analysis, and project execution.
• Commitment to staying current with emerging trends in molten salt technology and nuclear safety standards.
• Familiarity with ASTM, ISO, or other standards in material testing and quality assurance.

• Experience working in the nuclear industry or highly regulated environment.
• Background in reactor materials…
