• Manage and respond to Requests for Information (RFIs) from regulatory bodies and stakeholders, ensuring timely, accurate, and professional communication.
• Develop and implement strategies to manage technical and regulatory risks, ensuring alignment with project objectives and safety requirements.
• Ensure all documentation associated with Radiant reactor demonstrations is comprehensive, self-consistent, and maintained throughout the system lifecycle, adhering to regulatory and industry standards.

• Bachelor’s or advanced degree in nuclear engineering or a closely related field (e.g., mechanical engineering, chemical engineering, or physics with a nuclear focus)
• 5+ years of relevant experience
• Demonstrated experience with multi-physics simulations and transient analysis of reactor systems, including familiarity with tools such as MCNP, RELAP5, or similar software.
• Experience in nuclear regulatory compliance, safety analysis, or risk assessment (e.g., PRA, Haz Op, PHA, or FMEA).
• Proficiency in performing complex safety and risk analyses, with a focus on nuclear reactor systems.

• Strong technical writing skills, with the ability to produce clear, concise, and regulatory-compliant documentation.
• Demonstrated experience interacting with regulators, stakeholders, and cross-functional teams.

• Must be willing to work extended hours and weekends as necessary to accomplish our mission.
