  • Candidates should possess deep knowledge of Linux systems, cluster management tools (e.g., SLURM, PBS), parallel file systems (e.g., Lustre, GPFS), and high-performance interconnects (e.g., InfiniBand).
  • Extensive experience in classified environments is necessary, along with a thorough understanding of security policies and protocols.
  • Proven success in a supervisory or management role within a technical team is a must. This includes experience in project management and talent development.
  • Proficiency in scripting languages like Bash, Python, or Perl is expected for automation tasks. Familiarity with C/C++ or other scientific programming languages is also often preferred.
  • Excellent analytical and problem-solving skills are critical for diagnosing and resolving complex technical issues.
  • Strong verbal and written communication skills are essential for collaborating with technical teams, researchers, and executive leadership. 

 

Desired Skills:

  • Recent and demonstrated leadership experience within the DoD or Intelligence Community with emphasis on diverse technical environments.
  • High-performance computing (HPC) specialization such as cluster management, parallel computing, and performance optimization.
  • Hardware and software: The ability to deploy, administer, and monitor hardware and software components, from bare-metal installation to application troubleshooting, is a core responsibility. 
  • Information technology (IT) specialization such as systems architecture with proven experience in design, deployment, and maintenance; networking fundamentals, protocol and design, and cloud and virtualization technologies.
  • Security and compliance for classified environments
  • Security policies and frameworks: A solid understanding of accreditation frameworks (e.g., NIST 800-53, RMF, and JSIG), compliance policies, and security threats is critical.
  • Implementation: Experience implementing and managing security infrastructure, countermeasures, and tools is essential for safeguarding classified information

  

Special Requirement: 

This position requires the ability to obtain and maintain a Sensitive Compartmented Information (SCI) clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program.  In addition, due to the SCI, you may also be subject to random polygraph testing. 

  

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.  

This position will remain open for a minimum of 5 days after which it will close when a qualified candidate is identified and/or hired.

We accept Word (.doc, .docx), Adobe (unsecured .pdf), Rich Text Format (.rtf), and HTML (.htm, .html) up to 5MB in size. Resumes from third party vendors will not be accepted; these resumes will be deleted and the candidates submitted will not be considered for employment.
