Data Systems Senior Systems Architect/Engineer

Requisition Id17449

Overview:

The Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL) is seeking a Data Systems Senior Systems Architect/Engineer for its Earth Sciences Informatics portfolio. In this role, you will design, deploy, and maintain facility-wide infrastructure that supports high-performance computing (HPC), research, instrumentation, engineering, and operational workloads across a collaborative network spanning nine DOE National Laboratories for the Atmospheric Radiation Measurement (ARM) Facility. This is a unique opportunity to work at the intersection of national security, scientific research, and cutting-edge infrastructure engineering.

In this role you will design, implement, and maintain the data, compute, storage, virtualization, security controls, and networking infrastructure that supports BER scientific data programs and facilities. As a technical lead on projects spanning the national laboratory complex, you will ensure interoperability, security, and performance while collaborating with partner labs to meet research and operational needs. You will architect high-availability and disaster recovery solutions, monitor system health proactively, and maintain compliance with DOE orders, NIST 800-53, and FISMA. You will automate provisioning and patching with tools like Ansible, Puppet, or Terraform, support the integration of HPC clusters, AI infrastructure, and storage systems such as NFS, GPFS and Ceph. As part of this role, you will be actively collaborating with diverse teams and mentoring junior staff.

The ARM Data Center processes, archives, and distributes atmospheric observations from observatories around the globe, and provides data, computing and AI infrastructure, and analysis tools to the scientific community. Your work will directly improve how our community accesses and uses vast quantity of atmospheric and earth science data.

Major Duties/Responsibilities:

• Design, implement, and maintain facility-wide systems infrastructure including compute, storage, virtualization, and networking environments supporting DOE BER data programs and facilities.
• Serve as a technical lead for infrastructure projects coordinated across the national laboratory complex, ensuring interoperability, security, and performance standards are met facility-wide.
• Work with distributed teams to enable data collection, secure transfer, data processing, and distribution.
• Architect and support high-availability and disaster recovery solutions for mission-critical systems.
• Collaborate with engineers, scientists, and IT staff at partner national laboratories to align infrastructure strategy with research and operational requirements.
• Monitor system performance, capacity, and health; proactively identify and resolve issues before they impact operations.
• Research new and emerging technologies and successfully design and deploy for data center operations.
• Implement and maintain security controls in compliance with DOE orders, NIST 800-53, FISMA, and other applicable federal cybersecurity frameworks.
• Automate infrastructure provisioning, configuration management, and patching using tools such as Ansible, Puppet, or Terraform.
• Support integration of HPC clusters, AI infrastructure, data storage systems (e.g., NFS, GPFS, Ceph), and networking (including high-speed interconnects) for facility operations.
• Address critical incidents affecting data center operations and/or interlab connectivity.

• Develop and maintain detailed system documentation, standard operating procedures, and disaster recovery plans.
• Mentor junior engineers and contribute to a culture of technical excellence and continuous improvement.

Basic Qualifications:

• BS degree in Computer Science, Computer Engineering, Information Systems, or a related field (or equivalent experience).
• 5+ years of experience in systems engineering, data center operations, or enterprise infrastructure roles.
• Strong hands-on experience with Linux/Unix and Windows Server administration at scale.
• Deep understanding of virtualization technologies (VMware, KVM, or similar).
• Experience with enterprise storage systems, SAN/NAS architectures, and backup/DR solutions
• Solid networking knowledge (TCP/IP, VLANs, routing/switching, firewalls).
• Experience working within federal or DOE cybersecurity compliance frameworks (NIST 800-53, RMF, FISMA).
• Demonstrated ability to work across distributed, multi-site organizations and manage competing stakeholder priorities.
• Excellent troubleshooting, documentation, and communication skills.

Preferred Qualifications:

• Experience supporting HPC environments or scientific computing infrastructure.
• Familiarity with DOE National Laboratory systems, governance, or interlab collaboration models.
• Experience with configuration management and infrastructure-as-code (Ansible, Terraform, Puppet, Chef).
• Relevant certifications (e.g., RHCE, CISSP, VCP, or equivalent).
• Experience with container orchestration (Kubernetes, OpenShift) in a research or federal environment.

Special Requirements:

• Visa sponsorship is not available for this position.

• 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.
