In-Core Material Performance Modeling Engineer

Aalo Atomics; Austin (TX); On-site; USD 90,000 - 135,000; Full time

Benefits offered by this job

Paid Time Off

Job summary

Aalo Atomics seeks an engineer to model in-core performance and lifetime of fuel and core components under irradiation, thermal, chemical and mechanical environments. This role collaborates with mechanical design, neutronics, and thermal-hydraulics to translate results into design guidance and defensible lifetime assessments.

Open to early-career to senior candidates; reports to the technical lead for core and fuel material-performance modeling. On-site in Austin, TX or Idaho Falls, ID.

Qualifications

• Degree in nuclear engineering, mechanical engineering, materials science, computational engineering, or related field.
• Strong grounding in material behavior, heat transfer, solid mechanics, and numerical modeling.
• Ability to construct models that accurately represent the important physics, not only run software.

Responsibilities

• Develop and apply models for fuel, graphite, and core metallic components using BISON/MOOSE and related tools.
• Predict irradiation, temperature, stress, chemistry, and operating history effects on dimensions, properties, and life.
• Collaborate with mechanical designers to evaluate materials, geometry, tolerances, interfaces, and lifetime margins.
• Translate modeling results into design inputs, operating limits, test needs, and lifetime criteria.
• Develop or adapt material and constitutive models for relevant physics.
• Use Python for data processing, analysis automation, visualization, and reporting.
