We are building a next-generation nuclear energy company focused on a single, standardized microreactor core deployed in two variants: terrestrial power and lunar/space power.

Our mission is to deliver portable, long-life, factory-fabricated nuclear systems that are safe, licensable, and scalable. We are seeking a Senior Nuclear Engineer to take technical ownership of reactor physics, neutronics, and core safety analysis for our unified reactor platform.

This role is central to the credibility, licensability, and long-term success of the company. You will work closely with systems, thermal, mechanical, and licensing teams to mature a reactor design intended for real deployment—not paper studies.

Own reactor physics and neutronics analysis for the core across terrestrial and space variants

• Perform steady-state and transient analyses, including reactivity coefficients, kinetics parameters, shutdown margins, and power distributions
• Develop, validate, and document modeling methods using Monte Carlo and deterministic tools
• Support safety analysis, fault response modeling, and design basis events
• Assess conservatism, uncertainties, and assumptions in nuclear calculations
• Interface with systems, thermal-hydraulics, materials, and mechanical engineering teams
• Contribute to licensing strategy, regulatory documentation, and external technical reviews
• Mentor junior engineers as the team grows

• Degree in Nuclear Engineering or closely related field (MS or PhD preferred)
• 6+ years of experience in nuclear reactor analysis, design, or safety
• Strong experience with neutronics tools such as MCNP, Serpent, OpenMC, SCALE, or equivalent
• Experience documenting analysis methods for internal, regulatory, or external stakeholders
• Ability to work across disciplines in a fast-moving technical environment

• Meaningful equity participation in a foundational nuclear platform
• Competitive medical, dental, and vision coverage
• Flexible PTO and paid holidays
• Direct access to leadership and real technical authority
• Opportunity to shape a reactor that will operate on Earth and beyond

If you are motivated by building a reactor that will actually be deployed rather than endlessly redesigned, then we want to speak with you. This is a rare opportunity to help define a unified nuclear platform from first principles through operation.
