Oak Ridge National Laboratory is the US Department of Energy’s largest multi-program science and energy laboratory, with scientific and technical capabilities spanning the continuum from basic to applied research. Located in the city of Oak Ridge, ORNL is in the eastern part of Tennessee in the foothills of the Great Smoky Mountains.

The National Center for Computational Sciences in the Computing and Computational Sciences Directorate at the Oak Ridge National Laboratory (ORNL) seeks to hire Computational Scientists. We are looking in the areas of Computational Climate Science, Computational Astrophysics, Computational Materials Science, and Computational Plasma Physics, to serve as liaisons between the National Center for Computational Sciences (NCCS) and the users of the NCCS computing resources. We are also looking for you to develop and apply innovative ways to develop new scientific understandings while using ORNL’s world-class computational resources.

Duties/Responsibilities:

You will work with application scientists to develop, integrate, port, and tune applications, as well as develop new approaches to take full advantage of the capabilities of the NCCS leadership computing environment. You will represent the needs of domain specific application groups for NCCS planning and decision-making.

Work closely with the NCCS users to assist them in exploiting the resources of the NCCS effectively and efficiently. Partner with large user program projects in moving data and programs into and out of the NCCS environment, developing, porting, and scaling applications and algorithms for NCCS computers, debugging and tuning applications for high performance, and scheduling applications at scale to meet the scientific needs of the users. Work with NCCS systems, storage and networking groups to understand the needs and schedules of the various domain application groups. Assist in capability planning exercises. Define the requirements for, and assist in developing system software, libraries and tools that meet the application communities’ needs.

Participate in high-performance-computing community-wide efforts to design new methodologies, workflows, tools, and other contributions that will advance the state of the art in computational science. Where appropriate, write proposals and conduct research to determine the best way to approach tools, libraries, emerging methods and workflows, as well as figuring out the best path forward for application development on future NCCS resources. Participate in various application-area and computer-science research proposals. Conduct the research and report results in journals, technical manuals, and conferences.

Basic Qualifications:

• Ph.D. with a minimum of 2 years of experience, computational science, applied mathematics, computer science, or related scientific discipline is required.
• Experience with one or more of the following: numerical methods, parallel algorithms, MPI, Fortran and parallel software development on large scale computational resources is required.
• Excellent interpersonal skills, oral and written communications skills, organizational skills, and strong personal motivation are necessary.
• Ability to work in a dynamic, team environment is required.

Preferred Qualifications:

• Ph.D. coupled with 5 years of experience, in a computational science domain, applied mathematics, computer science, or related scientific discipline.
• Experience with C, C++, vectorization or one-sided asynchronous programming models is a plus.
