Scientific Group Leader, Architectures and Performance


Interested in taking your scientific computing skills to the next level? We are seeking a senior computer scientist to lead a world class research group in the areas of Architectures and Performance for the Oak Ridge National Labs (ORNL) and Department of Energy (DOE) missions. Responsibilities include group technical leadership and management, and research.

The Architectures and Performance Group (APG) designs and prototypes the scientific computing systems of tomorrow. APG works closely with domain scientists to solve key computational challenges in DOE’s scientific mission. We coordinate and partner with other groups across ORNL, other national laboratories, academic, and industry to investigate the fast-moving, dynamic landscape of computing.

This challenging position is in the Advanced Computing Systems Section within the Computer Science and Mathematics (CSM) Division. CSM delivers fundamental and applied research capabilities in a wide range of areas, including applied mathematics and computer science, experimental computing systems, scalable algorithms and systems, artificial intelligence and machine learning, data management, workflow systems, analysis and visualization technologies, programming systems and environments, and system science and engineering.

As a U.S. 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 champion 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 essential 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.


You will have the opportunity to provide Research and Development (R&D) leadership to a group that strategically advances science and technology consistent with ORNL’s status as the world’s premier R&D institution!
