Résumé du poste

Aalo Atomics, based in Austin, TX, is seeking an engineer to model in-core performance and lifetime of fuel and core components under irradiation, temperature, and chemical environments. You will collaborate with mechanical design, neutronics, and thermal-hydraulics teams to translate modeling results into design guidance and lifetime criteria.

Early-career engineers will receive mentorship while more experienced candidates may own larger analysis areas and drive cross-functional integration.

Qualifications

• Degree in nuclear engineering, mechanical engineering, materials science, computational engineering, or a 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 simply operate analysis software.
• Experience with finite-element or multiphysics analysis; BISON/MOOSE experience is strongly preferred.
• Proficiency with Python for engineering analysis and visualization.
• Understanding of model verification and validation, software quality assurance, and reproducible analysis.
• Ability to work effectively with mechanical designers and engineers across materials, neutronics, and thermal-hydraulics.
• Sound technical judgment appropriate to the candidate’s level of experience.
• Ability to learn quickly, work with incomplete data, and clearly identify model limitations.
• Earlier-career candidates may bring strong fundamentals, computational ability, and the capacity to develop sound physical and modeling judgment under close technical mentorship.
• More experienced candidates should be able to independently define modeling approaches, assess model applicability and uncertainty, guide design decisions, and own technically defensible component-lifetime conclusions.

Responsabilités

• 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, material properties, structural behavior, and service life
• Work directly with mechanical designers to evaluate materials, geometry, tolerances, clearances, interfaces, and lifetime margins
• Integrate inputs from neutronics and thermal hydraulics, and assess how changes in reactor conditions or component design affect in-core degradation and performance
• Translate modeling results into actionable design inputs, operating limits, test needs, and lifetime criteria
• Develop or adapt material and constitutive models where existing capabilities do not adequately represent the relevant physics
• Use Python for data processing, analysis automation, visualization, and communication of results
• Apply rigorous software quality assurance, verification, validation, sensitivity analysis, and uncertainty quantification
• Develop defensible, physics‑based analysis methods where established codes or directly applicable design rules are insufficient
• Use AI‑assisted tools to accelerate analysis, model development, data review, and documentation while maintaining technical traceability and independently verifying results
• Clearly communicate model assumptions, limitations, uncertainties, and conclusions across engineering teams
