Oak Ridge, Tennessee
Postdoctoral Research Associate in Large Scale Simulations Job Opening in Oak Ridge, Tennessee - As a postdoctoral research associate in Oak Ridge National Laboratory?s (ORNL) Scientific Software Initiative, the selected candidate will provide research and development for numerous projects spanning a variety of scientific domains, applications, delivery platforms, programming languages, and hardware and software architectures.
This position will be an integral part of ORNL?s Scientific Software Initiative, which provides a broad range of software engineering and development services across the lab. The initiative supports this mission by cultivating an incredibly talented community of software professionals through focused training, recruiting, continuing education, and mentorship.
The Scientific Software Initiative currently contributes to scientific computing projects in advanced materials, advanced manufacturing and 3-D printing, astrophysics, battery technologies, neutron science, nuclear energy, neuromorphic computing, and quantum computing. Members of the initiative also contribute to computer science research projects and are active in the open source community, including the Eclipse Foundation. Most of these open-source projects are available on .
Major
The position requires collaboration within a multi-disciplinary research environment consisting of computational scientists, computer scientists, experimentalists, and conducting basic and applied research in support of the Laboratory?s missions. Specific responsibilities include participating in the design and architecture of integrated, multi-scale, coupled-physics computer codes, design and implementation of scalable numerical methods, uncertainty quantification, collaboration with experts from various scientific disciplines on coupled-physics issues, and following team planning, documentation, verification and validation, and software quality processes. Successful candidate will be expected to author peer-reviewed papers, technical reports, as well as represent the organization by giving technical presentations in public forums.
Application areas of particular interest include; quasielastic and inelastic neutron scattering, plasma-surface interactions in tokamaks, fission gas behavior in nuclear fuels, and phenomena encountered in additive manufacturing (3D printing) and related processes (melting, solidification, sintering, welding, etc.).
Qualifications Required
