About the role

This role requires innovative thinking, technical expertise, and a commitment to advancing safe and sustainable nuclear energy solutions.
Fissionaire's technology is subject to U.S. export control regulations, which require the company to review applicants' eligibility based on their citizenship or residency status.

Design and develop nuclear reactor systems, including core design, thermal-hydraulics, and safety systems, ensuring compliance with regulatory standards.
Perform simulations and analyses to optimize reactor performance, safety, and efficiency using industry-standard software tools.
Collaborate with multidisciplinary teams, including mechanical engineers, materials scientists, and safety analysts, to integrate reactor designs into broader systems.
Conduct risk assessments and safety analyses to ensure designs meet stringent nuclear safety requirements.
Prepare technical reports, design documentation, and presentations for internal stakeholders and regulatory bodies.
Stay updated on advancements in nuclear technology, materials, and regulations to incorporate cutting-edge solutions into designs.
Participate in project planning and scheduling to ensure timely delivery of design milestones.

Master's degree in Nuclear Engineering or a related field.
Minimum of 1-2 years of experience in nuclear reactor design, analysis, or related fields within industry or in academic work.
Proficiency with nuclear design and analysis software, such as MCNP, SCALE, RELAP5, COMSOL, MOOSE, GOTHIC etc.
Proficiency in programming languages for data analysis, scripting, or automation of design processes.
Knowledge of nuclear physics, neutronics, thermal-hydraulics, and reactor safety principles.
Familiarity with nuclear regulatory frameworks and safety standards.
Knowledge of materials science, particularly related to radiation-resistant materials and high-temperature applications.
U.S. citizenship or permanent residency required.
