Alion Science and Technology

Sr. Java Software Engineer (MV) - 38016

Norfolk, VA

Job Description

Alion has been providing modeling and simulation software to the Navy Service Program for over 20 years, and the exciting work we do keeps growing with new and continued demand for our state-of-the-art modeling and simulation software that allows Navy sailors to simulate actual warfare scenarios. The demands for Artificial Intelligence, Machine Learning, and sophisticated Cloud technologies requires that we rise to the challenge to meet the need for years to come. Come be part of this challenging, exciting software development opportunity! Read on for more details:

The Joint Simulation Bus (JBUS) Developer is responsible for the life-cycle software engineering of JBUS system interfaces to meet Navy Service Program Manager objectives. JBUS is the Navy Continuous Training Environment's (NCTE) primary application for performing simulation and C4I protocol translations and application level filtering. It bridges many architectures and protocols using plugins specialized for each architecture. JBUS translates messages both on the syntactic level, reordering fields and changing their datatypes, and on the semantic level, mapping enumerations and filling in missing fields and packets. The NCTE is an integrating architecture (networks, simulations, simulation routing equipment, data translation devices, and C5I systems) that forms a LVC range for distributed training. The JBUS Developer is a contributor to the NCTE software engineering activities in support of Fleet LVC training (LVCt), Joint LVCt, and Unit Level Training. NCTE Software Engineering provides modeling and simulation application development, LVC systems integration support, and in-service engineering support to US Fleet Forces (USFF) and the Number Fleets. The NCTE Software Engineering team is directly responsible, in this context, for developing and maintaining technical solutions and standards to provide the greatest level of training capability to the warfighter, at the lowest possible cost, at the fastest pace achievable.
