Senior Research Scientist Advanced Computing Systems

Major Duties and Responsibilities: Lead and grow a multidisciplinary team of research scientists and postdoctoral researchers focused on next-generation HPC systems architecture, providing mentorship, technical direction, and career development guidance. Define and execute a strategic research agenda in advanced computing systems architecture, with emphasis on hybrid classical-quantum computing systems, next-generation high-performance interconnects, and future storage technologies for leadership-scale workloads. Architect and evaluate hybrid HPC-quantum computing systems, including co-design of system integration frameworks, communication substrates, and programming models that bridge classical and quantum computational resources. Lead research and development efforts in next-generation interconnect technologies, including evaluation of emerging fabric architectures, topology design, routing strategies, and in-network computing capabilities for exascale and post-exascale systems. Drive research into next-generation storage systems and hierarchies, including storage-class memory, disaggregated storage architectures, high-bandwidth parallel file systems, and data movement strategies at leadership scale. Lead collaborations with internal ORNL teams, DOE program offices, national laboratory partners, and industry and academic collaborators on advanced computing systems projects. Represent the OLCF and ATS in high-visibility technical forums, standards bodies, and vendor co-design engagements relevant to future leadership computing system acquisition. Author and contribute to peer-reviewed publications, technical reports, and research proposals; secure external funding to sustain and grow the group's research portfolio. Evaluate and evolve state-of-the-art design processes and system characterization methodologies used at leadership computing facilities and disseminate findings and best practices to the broader HPC community.

Basic Qualifications: PhD. in computer science, computer engineering, electrical engineering, computational science, or a closely related field.8 or more years of relevant research experience beyond the Ph.D., with a demonstrated record of independent research accomplishment in HPC systems, computer architecture, or a closely related domain. Demonstrated experience leading or co-leading research teams, including supervision of staff researchers, postdoctoral associates, or graduate students.

Preferred Qualifications: Proven experience in HPC systems architecture, including large-scale system design, integration, and characterization at leadership computing facilities. Research experience with hybrid classical-quantum computing systems, including familiarity with quantum hardware platforms, quantum-classical interfaces, or co-design of hybrid algorithms and system software stacks. Deep technical knowledge of high-performance interconnect technologies, including emerging fabric architectures (e.g., high-radix topologies, CXL, UCIe, or comparable), routing, and in-network computing. Expertise in advanced storage systems for HPC, including parallel file systems, storage-class memory, disaggregated and composable storage, and high-performance I/O frameworks. Experience with heterogeneous node and system architectures, including accelerator-based computing and associated programming models. Experience collaborating with system vendors on co-design of hardware and software for future HPC platforms. Excellent interpersonal, oral, and written communication skills, with experience representing research programs to leadership, sponsors, and the broader scientific community. Strong personal motivation and the ability to thrive in a fast-paced, mission-driven applied research environment. Security, Credentialing, and Eligibility Requirements: 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. About ORNL:As a U.S. Department of Energy (DOE) Office of Science national laboratory, ORNL has an impressive 80-year legacy of addressing the nation's most pressing challenges. Our team is made up of over 7,000 dedicated and innovative individuals! Our goal is to create an environment where a variety of perspectives and backgrounds are valued, ensuring ORNL is known as a top choice for employment. These principles are essential for supporting our broader mission to drive scientific breakthroughs and translate them into solutions for energy, environmental, and security challenges facing the nation. ORNL offers competitive pay and benefits programs to attract and retain individuals who demonstrate exceptional work behaviors. The laboratory provides a range of employee benefits, including medical and retirement plans and flexible work hours, to support the well-being of you and your family.
