Formal supervisory experience is not required., Strong candidates will bring the first item plus experience in one or more of the others. We encourage you to apply even if you don't match every item. ## Description The Advanced Technologies Section (ATS) at Oak Ridge National Laboratory seeks a Senior Research Scientist to lead a research area developing integration models for the co-design of hybrid quantum-HPC systems. Work in this area spans system design, modeling, and digital twins and aims to define how quantum computers will be integrated into future scientific computing systems. The opportunity As overall lead of this research area, you will direct R&D into hybrid quantum-HPC system design, using digital twins and simulations to explore and test designs before they are built. The work seeks to address the questions of which classical HPC technologies are required in close proximity to a quantum computer, and how those tightly coupled resources integrate with large-scale HPC and AI facilities for science. The results will shape vendor co-design discussions and requirements for future scientific computing systems. You will lead the efforts of other research staff, postdocs, and graduate students working in this area. Your models will draw on measurements from ORNL's quantum-HPC testbeds, and you will work with industry partners and the broader HPC and quantum computing research community. You will define future R&D directions for Quantum-HPC systems architecture. We care most about depth in hybrid quantum-HPC system design and modeling. Broader HPC systems expertise strengthens the group, but no single candidate is expected to cover every area., * Serve as overall lead for the research area developing integration models for co-design of hybrid quantum-HPC systems: set its research agenda, plan milestones, coordinate contributors, and work with program leadership to report milestones and progress toward center and facility goals. * Drive R&D into hybrid quantum-HPC system design: integration architectures, communication paths between classical and quantum resources, and the system software that ties them together. * Build digital twins and simulations of hybrid quantum-HPC systems, calibrate them with testbed measurements, and use them to evaluate designs at scales and in configurations that don't exist yet. * Meet regularly with the research staff, postdocs, and graduate students working in this area to guide its technical direction, and mentor them in research design, publication, and proposal writing. * Extend the agenda into adjacent systems areas as the work matures, including the interconnects and data paths that link quantum and classical resources. * Represent ORNL in vendor co-design engagements, DOE program reviews, and community forums such as SC and IEEE Quantum Week. * Publish peer-reviewed work, write proposals, and secure external funding to grow the research portfolio., * Research on hybrid classical-quantum systems: quantum hardware platforms, quantum-classical interfaces, control systems, or hybrid workflows and software stacks. * HPC system design, integration, or characterization. * Modeling and simulation of computer systems, such as digital twins, architectural or network simulators, or performance models validated against real hardware. * Networks and interconnects that couple quantum and classical resources, such as low-latency links between quantum control systems and HPC nodes. * Heterogeneous and accelerator-based architectures, including GPUs working alongside quantum processors. * Co-design work with system vendors. * Clear communication with sponsors, leadership, and the research community. Special Requirements: Submit a CV and a one-page statement describing the systems research you would pursue on ORNL's quantum-HPC testbeds. and continue until the position is filled. Questions about the role can go to zimmercj@ornl.gov and questions about the application process can go to copemanrs@ornl.gov. * For employment at Oak Ridge National Laboratory (ORNL), a Real ID compliant form of identification will be required. Additionally, ORNL is subject to Department of Energy (DOE) access restrictions. All employees must also be able to obtain and maintain a federal Personal Identity Verification (PIV) card as mandated by Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which requires a favorable post-employment background investigation. * To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws. * For foreign national candidates: If you have not resided in the U.S. for three consecutive years, you are not eligible for the PIV credential and instead will need to obtain a favorable Local Site Specific Only (LSSO) risk determination to maintain employment. Once you meet the three-year residency requirement, you will be required to obtain a PIV credential to maintain employment.
