Job description

Overview

In this role you will lead the scientific modeling and simulation work for UTS-related capabilities, translating data into high-fidelity analytical outputs used by commanders and operators. You will shape methodologies, validate assumptions, and develop advanced agent-based and physics-based models to assess risks and improve mission survivability. This position blends theory with practical defense applications in a cross-disciplinary team, offering a clear impact on decision support and risk management. You will work on a transition-ready capability that enhances decision-making under uncertainty.
