Job Description

The Conflict Simulation Laboratory (CSL) of the Global Security Computing Applications Division (GS-CAD) within the Computing Directorate has an opening for a Senior Software Developer specializing in the analysis, design, development, and implementation of scientific software for the CSL. The CSL develops and deploys the Joint Conflict and Tactical Simulation (JCATS) and JCATS Low Overhead Driver (JLOD) simulation suites to users around the world.

The CSL also works closely with external partners to enable JCATS and JLOD to interoperate with other simulation models and tools in a federated environment to support more advanced training.

JCATS and JLOD are tactical simulations that model soldiers, tanks, and other military platforms maneuvering in a 3D environment. Line of sight, projectile paths, collision detection, and many other algorithms calculate real time results for military trainers and analysts. You will interface closely with sponsors and customers to determine simulation capability requirements and analyzes, designs, and implements new functionality using object-oriented programming (primarily C++) and classic computer science algorithms, while balancing performance tradeoffs.

CSL simulation products are used for training and analysis by 30 countries, the Departments of Energy and War, and other government agencies. Their applications include military operations, peacekeeping, drug interdiction, homeland defense, site security, and civil defense preparation. You will interact with team members, project management, sponsors, and users, and will assume responsibility for the development and sustainment of major CSL simulation capabilities.
