We are seeking a Nuclear Engineer, Reactor Physics who will be responsible for performing reactor physics analyses of the nuclear reactor power systems in development at Nano Nuclear Energy, Inc. The Nuclear Engineer will support core design enhancement, integrate customer and regulatory requirements into the reactor core design, and perform analysis and prepare documentation to support licensing of the reactor systems.

Responsibilities
  • Perform neutron and gamma radiation transport calculations to determine activation/dose rates, heating, and material damage effects, and establish radiation shielding requirements.
  • Design radiation shielding throughout the reactor system.
  • Perform criticality safety calculations.
  • Develop, verify, and validate computational tools for reactor multiphysics analysis.
  • Collaborate with engineering, operations & maintenance, safety analysis, and licensing teams.
  • Assist in training and mentoring junior team members.
  • Ensure compliance with nuclear regulations, licensing requirements, and company safety policies.
  • Contribute to the preparation of documents to enable licensing of Nano Nuclear Energy reactor systems.
  • Responsibilities may extend to other divisions of the business at times.
  • Bachelor’s degree in Nuclear Engineering or related field.
  • 7+ years (or M.Sc. and 5+ years) of relevant experience.
  • Strong Monte Carlo skills and strong understanding of reactor physics. Experience in reactor design, radiation shielding, and criticality safety desirable.
  • Strong programming skills in any language; Python is commonly used in this position.
  • Excellent problem‑solving and collaboration skills.
  • Nuclear software verification and validation experience is a plus.
