Job summary

Applied Atomics is recruiting a Nuclear Engineer to own the technical development of our reactor core, fuel, and nuclear systems. You will define the nuclear architecture, lead early-stage reactor and fuel design, and interface with reactor-licensing partners.

You will tackle reactor physics, shielding, safety analyses, and model verification across a fast-paced hardware environment, with growth toward leading a world-class engineering team.

Qualifications

• Bachelor's degree in Nuclear Engineering or related field (required).
• 4+ years of nuclear engineering experience (or 2+ years with MS).
• Experience with radiation transport and reactor physics modeling tools (OpenMC, MCNP, Serpent, SCALE).
• Experience with reactor design, core physics, criticality, and shielding.
• Basic understanding of thermal-hydraulics and coupled neutronics-thermal models.
• Familiarity with CAD tools (NX, SolidWorks, Creo).
• Ability to operate across cross-functional teams; strong written and verbal communication.
• Self-starter with ownership mindset to drive concepts to deployment.

Responsibilities

• Own reactor physics, neutronics, shielding, and nuclear design from concept to deployment.
• Develop core design, reactivity coefficients, kinetics parameters, feedback mechanisms, and spectra.
• Perform radiation transport, shielding, and criticality safety analyses.
• Conduct transient and accident-scenario evaluations for safety basis development.
• Lead V&V efforts for nuclear analysis tools and workflows.
