POSTED ON 5/31/2026
AVAILABLE BEFORE 7/7/2026
Requisition Id 16407

Overview:

The National Center for Computational Sciences (NCCS) at Oak Ridge National Laboratory (ORNL) operates the fastest High Performance Computers (HPC) in the world. We are seeking an experienced security engineer who can bridge hands-on engineering and security governance to ensure the security, performance, and reliability of the NCCS computing infrastructure. Our efforts support a highly-skilled user base consisting of the best-of-the-best science teams around the world. If you are excited about applying DevSecOps and risk-based security practices to HPC, come help us protect the integrity of open science publications and national interests that rely on NCCS supercomputing resources and expertise.

The Team:

The HPC Cybersecurity Engineering team is one half of the NCCS Security and Information Engineering Group. We architect, develop, deploy, and maintain the supercomputing-specific security program (an enclave within the broader ORNL authorization boundary) and provide HPC security expertise to projects of national interest. We collaborate across incident response, blue team engineering, vulnerability research, policy architecture, and DevSecOps. We work closely with scientific and operations teams and act as liaisons to ORNL’s broader risk management framework. We are a Linux focused environment with security challenges that prioritize scale, performance, and scientific computing integrity.

About You:

You automate wherever possible, using Infrastructure as Code (IaC) and repeatable patterns so security can scale with operations. You can translate governance requirements into implementable standards and aggregate technical realities into clear risk-based decision options for leadership. You collaborate well, document what matters, and enjoy driving improvements that are both technically sound and audit ready. You may have more than a couple of our Preferred Qualifications and probably do not yet have any prior HPC experience. You may have technical leadership experience and/or want to grow into this role. You may or may not think Hackers is an incredible movie.

Major Duties/Responsibilities:

  • Translate complex technical concepts to communicate effectively with scientific, operations, project, and management staff
  • Help shape the Supercomputing security architectural vision and lead security reviews of new capabilities, services, and designs against core security plans
  • Design, implement, and automate policy/control assessments to verify cybersecurity and operational policy compliance
  • Engineer secure software development frameworks, tools, and guardrails that enable teams to deliver securely at HPC scale
  • Define and implement best practices, standards, and technical baselines within the organization
  • Analyze, triage, and respond to application, system, and network security relevant events
  • Serve as a security liaison for projects of national interest and external partners
  • Interpret cybersecurity policy and requirements; recommend enhancements to current policies/standards and lead implementation efforts with stakeholders
  • Lead vulnerability management activities including remediation coordination, patch planning, verification, and approved penetration testing
  • Document cybersecurity procedures, standards, control narratives, and decision records to support operations, audits, and continuous improvement
  • Participate in a 24/7 on-call incident response rotation

Basic Qualifications:

  • Bachelor’s degree in Computer Science, Cybersecurity, or related field
  • Minimum of five years of relevant experience
  • Equivalent combination of education and experience will be considered

Preferred Qualifications:

  • Master’s degree in Computer Science, Cybersecurity, or related field and at least eight years of relevant experience
  • Strong understanding of U.S. Federal cybersecurity frameworks, standards, and guidelines including FISMA, NIST RMF (SP 800-37) and SP 800-53, FIPS 199/200, FedRAMP, and OMB Memorandums
  • Experience as an Information Systems Security Officer (ISSO) and/or administering systems in UNIX/Linux environments
  • Solid understanding of networked computing concepts and common protocols (DNS, DHCP, LDAP, SNMP, SMTP, HTTP(S), TLS/SSL)
  • Experience representing organization during security cybersecurity audits
  • Familiarity building or operating security tools such as SIEMs, vulnerability scanners, NIDS/HIDS, server telemetry, and detection engineering
  • Experience with incident response and Linux forensics
  • Familiarity with automated configuration management tools
  • Experience in network, application, and/or security architecture and design, including threat modeling and security review practices
  • Experience in a high-performance computing environment (nice to have), including multi-tenant compute, high-speed interconnects, and parallel filesystems
