Systems Programmer in Extreme Scale Computing

Company Name:
Oak Ridge National Laboratory
Help enable the best and most productive use possible of emerging exa-scale high-performance computers and develop revolutionary approaches to reducing time to solution of extreme-scale computing and computational science problems.

ORNL's computational expertise is built on a foundation of computer science, mathematics, and "big data"--or data science. The projects we undertake run the gamut from basic to applied research, and our ability to efficiently apply the massive computing power available at ORNL across a range of scientific disciplines sets us apart from other computing centers. We have decades of experience in developing applications to support basic science research in areas ranging from chemistry and materials science to fission and fusion, and we apply that expertise to solving problems in a number of other areas.
