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.

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.
