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.
Contribute to the creation of quality deliverables and reports and quality control thereof.

Desired:

Master’s Degree in Computer Science, Operations Research, or other STEM field, with 10 years of relevant experience
6+ years of demonstrated proficiency developing and employing mission-level models within AFSIM or comparable simulation environments
Proficiency in model-based systems engineering tools such as CAMEO
Proficiency in SysML

Scheduled Weekly Hours: 40hrs

Basic Compensation: The offered rate will be based on the selected candidate’s knowledge, skills, abilities and/or experience and in consideration of internal parity.
