Peraton•Stennis Space Center, MS

1d•Onsite

About The Position

Peraton requires a software systems engineer to support the Naval Research Laboratory (NRL) ocean modeling team in Scientific Software Development at the Stennis Space Center, Mississippi. The role involves utilizing METOC simulation pipelines, data assimilation systems, and high-performance computing to support the development and optimization of Navy ocean models, including the Hybrid Coordinate Ocean Model (HYCOM) and the Navy Coupled Ocean Data assimilation (NCODA) system. The developer will also be responsible for developing, testing, and debugging scientific software using languages such as Fortran, Python, and C++, and integrating with Navy-specific systems like NCOM and NCODA-var to improve model performance and support the transition of research to operational systems. Key activities include improving model coupling, enhancing data assimilation techniques, creating and maintaining comprehensive software documentation, and contributing to technical reports and publications.
