Research Software Engineer (Scientist 2)

What You Will Do

Join our world-class team! Now is your chance to make a difference in supporting our national security mission. The XCP-4 (Continuum Models and Numerical Methods) is seeking applicants for Bachelor's/Master's/PhD level computer scientists with interest in research software engineering. XCP-4 is responsible for the design and implementation of a wide variety of physical models including high explosive and turbulence models and is a leader in the development of numerical methods for hydrodynamics simulations, remap and code linking algorithms, and more.

The successful candidate is expected to work in a team environment to develop and implement computational and numerical methods in code linking and remap software.

The successful candidate will work in all parts of the development lifecycle to include software design and engineering, user support and documentation. Code linking is a multi-disciplinary endeavor; therefore, the ability to work well in a team environment is extremely important, as is the ability to interact with users in an efficient and productive manner.
