Principal Materials Design Scientist

Develop and execute thermomechanical and thermohydraulic models to predict performance, deformation, heat flux, stress, fluid–structure interactions and materials degradation and lifetime. - Evaluate materials' thermophysical properties and integrate them into modeling workflows. - Work closely with testing engineers to validate models against thermomechanical and thermohydraulic experiments. Interpret test data to refine models, reduce uncertainties, and drive design decisions. - Design new materials, coatings, or composites optimized for high thermal loads, thermal cycling, or combined thermomechanical stresses. Recommend material compositions and microstructural features to meet performance targets. - Partner with design engineering teams to integrate materials models into system level simulations. - Communicate complex modeling results to nonexperts through clear visualizations, reports, and presentations. Required Skills:

Master's or PhD in Materials Science, Mechanical Engineering, Nuclear Engineering, Chemical Engineering, Aerospace Engineering, or related fields. - Strong background in heat transfer, fluid dynamics, thermodynamics, and solid mechanics. - 8+ years of experience in thermomechanical and/or thermohydraulic simulation tools (COMSOL, ANSYS, Abaqus, OpenFOAM, etc.)

8+ years of experience with multiphysics modeling, including coupled heat transfer/fluid flow/stress problems. - Proficiency in scripting languages (Python, MATLAB) for model automation, data processing, or custom solvers. - Strong analytical, problem solving, and communication skills. - Experience with CAD preferred.
