• Support modeling, simulation, and software development efforts across the full analytic and software development lifecycles.

• Support the analytic team lead in the execution of study plans.

• Collaborate with military subject matter experts and other stakeholders to characterize architectures and concepts under study in the simulation environment.

• Contribute to the development of modeling approaches, experiment designs, and analytic methods.

• Instantiate combat system, platform, and behavior models in the simulation environment.

• Instantiate kill chains, battle management command and control relationships, and other scenario-specific mission and operational factors in the simulation environment.

• Support the development and instantiation of an experiment design in the simulation environment.

• Provide technical guidance to less experienced engineers and analysts when required.
