High Performance Computing (HPC) Cluster Administrator – Contract Position
At Lightbridge, we’re pioneering advanced nuclear fuel technology that’s designed to make reactors safer, more efficient, and more responsive to global energy needs. Our mission is bold—and we’re looking for equally bold thinkers to help us bring it to life. If you thrive at the intersection of engineering and regulatory strategy, this is your opportunity to help shape the future of clean energy.
About the Role: High Performance Computing (HPC) Cluster Administrator – Contract Position
Lightbridge is looking for an HPC Cluster Administrator. This position is a contract position where you will manage and optimize our high-performance computing environment to support advanced nuclear simulations and engineering workflows. You’ll work closely with internal teams and external partners to ensure secure, efficient, and compliant operations.
What You’ll Be Doing
- Manage HPC internal user accounts, user accounts data flow, storage allocations, folder access control and code access for Export control and ITAR.
- Deploy Slurm and setup queue management.
- Create and develop a data control plan in compliance with ITAR and export control.
- Install, upgrade, and maintain scientific software, applications, and hardware.
- Maintain software verifications and version control for nuclear software quality assurance.
- Assist engineers with scripting for job submittals using shell files, as specific settings will need to be known for the HPC system and how they will apply to the coding.
- Maintain and manage personnel access control to the HPC (virtually).
- Work with Physical Colocation partner over planned outages and external factors.
- Work with code vendors to maintain compliance with software being available on a shared computing cluster (BISON, MCNP, SCALE, and other controlled codes on the user level).
- Implement HPC OnDemand software for GUI implementation for less experienced Linux Users.
- Create and maintain technical documentation, user guides, and deliver training sessions on HPC usage.
- Work with Quality Assurance Manager to develop software quality assurance plan (SQA)
Who You Are
- BS in Computer Science, Computer Engineering or related field + 5 years of relevant experience, or MS + 4 years of relevant, or PhD + 3 years of relevant experience
- In-depth knowledge of Linux operating systems (RedHat), including RHEL, CentOS, or SLES, and system administration in a cluster environment.
- Proficiency in one or more scripting languages such as Perl, Shell, Python, or Bash for task automation and system management.
- Experience with high-speed networking technologies, including InfiniBand and Ethernet.
- Expertise with high-speed storage and parallel file systems, such as Lustre, OSNexus, or GPFS.
- Experience with HPC job schedulers like Slurm or LSF.
- Experience with server installation, configuration, maintenance, and upgrades of hardware and scientific software.

About Lightbridge:
Lightbridge is developing Lightbridge Fuel™, an advanced metallic nuclear fuel for use in water-cooled reactors, including in the existing fleet of Nuclear Power Plants and in future water-cooled Small Modular Reactors.
Lightbridge Fuel consists of a metallic uranium-zirconium alloy fuel core and zirconium-alloy cladding which are co-extruded to form monolithic metallic fuel rods with a multi-lobed and helically twisted geometry. The design of Lightbridge Fuel gives it inherently superior technical performance in several key areas as compared to conventional commercial nuclear fuel, including lower fuel operating temperatures, enhanced coolability, and a more robust mechanical design. Lightbridge Fuel simultaneously offers improvements in safety, fuel performance, operational flexibility, power plant economics, and proliferation resistance.
Lightbridge has entered into two long-term framework agreements with Battelle Energy Alliance LLC, the United States Department of Energy’s operating contractor for Idaho National Laboratory, the United States' lead nuclear energy research and development laboratory. DOE’s Gateway for Accelerated Innovation in Nuclear program has twice awarded Lightbridge to support the development of Lightbridge Fuel over the past several years. Lightbridge is participating in two university-led studies through the DOE Nuclear Energy University Program at Massachusetts Institute of Technology and Texas A&M University. An extensive worldwide patent portfolio backs Lightbridge’s innovative fuel technology.
Lightbridge Corporation is a publicly traded company headquartered in Reston, Virginia, and is included in the Russell 2000® Index and the Russell 3000® Index. For more information, please visit www.ltbridge.com.
