Associate HPC Cybersecurity Engineer

Requisition  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 Dev Sec Ops  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 Associate 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 Dev Sec Ops .

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
