Why Work at BNL? Brookhaven National Laboratory (www.bnl.gov) delivers discovery science and transformative technology to power and secure the nation's future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department;of Energy's (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.
The Nuclear and Particle Physics Software (NPPS) Group in the BNL Physics Department is an international leader in scientific software development at the most challenging scales. The group collaborates on a growing number of experiments including the ATLAS experiment at the Large Hadron Collider in Europe; the Belle II experiment at the SuperKEKB accelerator in Japan; the STAR, PHENIX and sPHENIX experiments at BNL's RHIC heavy ion collider; and the future electron-ion collider (EIC). NPPS works with other ATLAS efforts at BNL including the Omega group, the Tier 1 facility, the US ATLAS Operations Program, and the US ATLAS Upgrade Project. The mission of the Computational Science Initiative (CSI) is to provide the laboratory an umbrella for research and development activities that address the computational needs of research programs both inside and outside of BNL, bringing together computer scientists, applied mathematicians and domain scientists to carry out leading edge research, convert research results into practical solutions that advance domain science and provide the necessary computing infrastructure services and training to support efficient operation.
The NPPS group has an opening for a postdoctoral research associate to work in an NPPS-CSI collaborative effort on adapting and developing HEP software for efficient execution on modern heterogeneous architectures, particularly GPUs, and optimizing high concurrency workflows on HPCs. The successful candidate is expected to bring their HEP software knowledge to bear on targeted projects to port and create/reengineer offline software packages in collaboration with parallel processing experts in CSI. The individual will be an ATLAS Collaboration member participating in the ATLAS scientific program and ATLAS software projects as well as working jointly with CSI on parallel software aspects. Through these joint projects, the individual will build an expertise base in parallelizing HEP codes, combining their domain knowledge with CS knowledge gained from CSI, and applying this expertise within and beyond ATLAS. The targeted projects will depend on the aptitudes and interests of the successful candidate, and may involve analysis, reconstruction and/or simulation software. The individual will have detailed knowledge of HEP offline software, analysis experience, and an interest in scientific software development as a potential career path. The candidate is expected to play an important role in developing and executing strategies for leveraging GPU-rich resources such as DOE Leadership Class Facilities for HEP computing. The hire will be based at BNL. Domestic and international travel is expected. The position will have an initial 2 year term, with the potential of a 3rd year.

About Brookhaven National Laboratory
Brookhaven National Laboratory is a multipurpose research institution funded primarily by the U.S. Department of Energy’s Office of Science. Located on the center of Long Island, New York, Brookhaven Lab brings world-class facilities and expertise to the most exciting and important questions in basic and applied science—from the birth of our universe to the sustainable energy technology of tomorrow. We operate cutting-edge large-scale facilities for studies in physics, chemistry, biology, medicine, applied science, and a wide range of advanced technologies. The Laboratory's almost 3,000 scientists, engineers, and support staff are joined each year by more than 4,000 visiting researchers from around the world. Our award-winning history, including seven Nobel Prizes, stretches back to 1947, and we continue to unravel mysteries from the nanoscale to the cosmic scale, and everything in between. Brookhaven is operated and managed by Brookhaven Science Associates, which was founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, and Battelle, a nonprofit applied science and technology organization.
