Oak Ridge National Laboratory is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.

We are seeking a Postdoctoral Research Associate who will support the Advanced Computing for Chemistry and Materials Group in the National Center for Computational Sciences (NCCS), Computing and Computational Sciences Directorate (CCSD) at Oak Ridge National Laboratory (ORNL) to perform leading-edge computational chemistry/materials research and development for applications in material sciences and condensed matter physics.

This role will involve performing leading-edge computational condensed matter and material sciences research and development. Priorities include the development, efficient parallel and GPU-enabled implementation, and application of first principles methods. Emphasis will be placed on robust, efficient, and sustainable software development practices including testing and documentation. The scientific effort will focus on the ground state and finite temperature properties of alloys, magnetic and quantum materials.
Close collaborations are expected with researchers from across ORNL with expertise in chemical separations, materials and nano science. The scientific effort will both predict materials properties as well as test and develop novel high performance computing methods for first principles materials calculations.

The successful candidate will be mentored and teamed with staff in the National Center for Computational Sciences. They will collaborate with leading computer and computational scientists at ORNL and external collaborators in the development and application of new computational techniques specifically targeted at the key DOE Office of Science missions.

As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an extraordinary 80-year history of solving the nation’s biggest problems. We have a dedicated and creative staff of over 6,000 people! Our vision for diversity, equity, inclusion, and accessibility (DEIA) is to cultivate an environment and practices that foster diversity in ideas and in the people across the organization, as well as to ensure ORNL is recognized as a workplace of choice. These elements are critical for enabling the execution of ORNL’s broader mission to accelerate scientific discoveries and their translation into energy, environment, and security solutions for the nation.
