Job Location: Oak Ridge, TN

Oak Ridge National Laboratory (ORNL) is the United States Department of Energy's largest science and energy laboratory tasked to provide the United States government agencies and departments with technology and expertise to support national and homeland security needs. Our diverse capabilities span scientific and engineering disciplines, enabling the Laboratory to explore fundamental science challenges and to carry out the research needed to accelerate the delivery of solutions to the marketplace. This position is part of ORNLs Scientific Software Initiative, which provides scientific software development expertise to the Laboratory, by providing software engineering and development services across the Laboratory in a broad range of areas and topics. The Initiative supports the mission of the Laboratory by building a community for software professionals at the Laboratory to connect people, projects, and interested parties; by providing software engineering expertise for development, evaluation, quality assurance or other needs; by providing training and continuing education opportunities; by providing fair performance evaluation criteria; by recruiting new software engineering talent; and by mentoring students and early career scientists and engineers.The Initiative currently contributes to scientific computing projects in advanced materials, advanced manufacturing and 3D printing, astrophysics, batteries, neutron science, nuclear energy, and quantum computing. It also contributes to pure computer science projects. Initiative members are active in the open source community, including the Eclipse Foundation, and most Initiative projects are available on this role you will have a phenomenal opportunity to conduct research and development for numerous projects spanning a variety of scientific domains, applications, delivery platforms, programming languages, and hardware and software architectures.

Major Duties/Responsibilities:
Collaboration within a multi-disciplinary research environment consisting of computational scientists, computer scientists, experimentalists, and engineers/physicists conducting basic and applied research in support of the Laboratorys missions.
