## Description

Peraton requires a software systems engineer to support the Naval Research Labatory (NRL) ocean modeling team in Scientific Software Development at the Stennis Space Center, Mississippi.

What you will do:

 * Utilize 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
 * Develop, test, and debug scientific software using languages such as Fortran, Python, and C++, and integrate with Navy-specific systems like NCOM and NCODA-var to improve model performance and support the transition of research to operational systems. Improve model coupling, enhance data assimilation techniques, create and maintain comprehensive software documentation, and contribute to technical reports and publications as required to support the overall objectives of NRL Code 7320
