Advanced Reactor Multiphysics Simulation Analyst

Idaho National Laboratory needs Advanced Reactor Multiphysics Engineer to develop, deploy, and support innovative technical solutions across platforms including mobile, embedded, desktop, and web-based capabilities supporting programmatic goals. You'll apply software engineering principles to complex analytical processes and information visualization, leverage modeling and simulation to address problems in nuclear applications, chemistry, digital twins, critical infrastructure, and energy security, and analyze, test, modify, document, and maintain simulation-based systems.

Your work includes executing computational analysis tasks, developing and reviewing designs and requirement definitions, optimizing and programming software using MATLAB, Simulink, C/C++, Python, and similar technologies, and providing consultation services on applicable technologies and testing processes. You'll continuously enhance skills with cutting-edge technology, deliver high-quality features exceeding client expectations, and potentially mentor junior staff while advancing Idaho National Laboratory's mission in energy and national security.
