Job Location: Oak Ridge, TN

The National Center for Computational Sciences (NCCS) in the Computing and Computational Sciences Directorate at the Oak Ridge National Laboratory (ORNL) seeks to hire Computational Scientists. We are adding research staff in a wide variety of computationally intensive scientific research domains that include Computational Astrophysics, Computational Materials Science, Computational Plasma Physics, Computational Biophysics, as well as in areas related to data-intensive and data-driven science, and applications of emerging AI technologies. In this role, you will serve as a liaison between the National Center for Computational Sciences (NCCS) and the users of the NCCS leadership computing resources. You will also be expected to develop, apply, andpublish innovative ways to advance scientific knowledge using ORNLs world-class computational resources.

Major Duties/Responsibilities:
Work with other 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. Help represent the needs of selected domain specific applications for NCCS planning and decision-making. Work closely with the NCCS leadership computing user community as partners with projects to exploit the resources of the NCCS effectively and efficiently. This includes partnering with large user program projects in moving data and programs into and out of the NCCS computational environment, developing, porting, and scaling applications and algorithms for NCCS computers, tuning applications for high performance, and scheduling applications to execute at scale to meet the scientific capability needs of the users. Interact with NCCS systems, storage and networking groups to understand the needs and schedules of the various domain application groups. Assist in capability planning exercises and in defining requirements for, and assisting in the development of 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 optimal paths forward for application development on future NCCS resources and publish these results in the computational science literature. Particpate in various application-area and computer-science research proposals that allow for the conduct of scientific research that will be reported on in journals, technical manuals, and conferences is also encouraged.

Qualifications Required:
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.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. 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.ORNL is an equal opportunity employer. All qualified applicants, including individuals with disabilities and protected veterans are encouraged to apply. UT-Battelle is an E-Verify employer.
