SME Scientists and Science Technicians Group

Opportunity

CACI is seeking a SME Scientists and Science Technicians Group 2 in support of a program whose initiative is aimed at combating evolving and emerging threats, supporting related exploitation and replication activities, and advancing operational rehearsal, exercise, wargaming, and counter system development. Additionally, we are focusing on integration and experimentation, including Modeling and Simulation. By joining this team, you will have a unique opportunity to contribute to the U.S. and our allies’ ability to develop and apply models and simulations throughout the lifecycle of military and commercial technologies and systems.

Your work will help ensure Warfighter readiness and the realization of future capabilities.
