Full Job Description

Position title: Nuclear Engineer III/IV (Reactor Design)

Location: Madison, WI

About Us:

Fissionaire is pioneering the next generation of nuclear technology to deliver safe, scalable, and sustainable energy. Our team is small, fast-moving, and mission-driven — combining deep technical expertise with a startup’s sense of urgency. As we grow, we’re designing the systems that will redefine what nuclear power can do for the world.

Job Summary:

We’re looking for a Nuclear Engineer III/IV to lead and contribute to the design, analysis, and optimization of our advanced nuclear reactor systems. The ideal candidate combines strong nuclear engineering fundamentals with hands-on design experience and the creativity to solve unprecedented challenges. This role requires innovative thinking, technical precision, and a proactive drive to advance clean energy technology from concept to reality.

Key Responsibilities:

Lead reactor core and system-level design activities, including thermal-hydraulic, neutronic, and mechanical aspects.
Perform analysis, simulation, and optimization using industry-standard nuclear design tools.
Integrate fuel, coolant, and structural components into coherent system designs that meet safety, performance, and economic targets.
Collaborate with mechanical, materials, and safety engineers to ensure design coherence and regulatory readiness.
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.
Conduct trade studies and sensitivity analyses to guide design decisions.
Participate in design reviews, safety analyses, and regulatory interactions
Stay current with emerging reactor technologies, materials research, and simulation methodologies.
Participate in project planning, budgeting, and scheduling to ensure timely delivery of design milestones.
Contribute to a culture of innovation, accountability, and technical excellence.

Qualifications

Master’s degree in Nuclear Engineering, Mechanical Engineering or a related field. Ph.D. preferred but not required.
Minimum of 3-5 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, ANSYS, SERPENT, OpenMC, or similar nuclear analysis codes.
Strong understanding of neutronics, thermal-hydraulics, fuel cycle analysis, and reactor physics.
Familiarity with CAD software for reactor component design.
Proficiency in programming languages for data analysis, scripting, or automation of design processes.
Knowledge of nuclear physics, neutronics, thermal-hydraulics, and reactor safety principles.
Demonstrated ability to translate analytical results into design decisions.
Experience with Molten Salt Reactor design.
Demonstrated ability to work independently, take initiative, and drive projects to completion with minimal supervision.
Excellent written and verbal communication skills for technical documentation and cross-functional collaboration.
Familiarity with nuclear regulatory frameworks and safety standards.
Knowledge of materials science, particularly related to radiation-resistant materials and high-temperature applications.
Experience with risk assessments and analysis (PRA, FMEA etc.)
Familiarity with computational fluid dynamics (CFD) for thermal-hydraulic analysis preferred.
U.S. citizenship or permanent residency required.

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. As part of the application process, candidates will be asked to indicate whether they are a U.S. citizen, green card, lawful permanent resident, asylee, or refugee resident to support this review. Because government authorization timelines can vary, Fissionaire is unable to consider alternate resident statuses where required approvals may not be obtainable within a timeframe that meets business needs.

What We Offer:

Competitive salary and equity options
Comprehensive benefits, holiday and PTO schedule
Opportunity to work with a groundbreaking, advanced nuclear startup
