Job Description
An employer is looking for a Linux Engineer to sit hybrid at the Pentagon. This team of ~11 supports and maintains IDS/IPS equipment, flow analyzers, and Linux/RHEL servers that drive mission-critical cybersecurity operations, including data pipelines and backup processing. The environment is heavily Linux-focused, requiring hands-on experience with configuring, installing, patching, hardening, and STIGing systems, as well as managing backups and supporting infrastructure tied to future initiatives.

This role will also support and maintain broader cybersecurity tools (IDS, IPS, Net Flow, SIEM, Snort, virtualization), partner with government and internal teams to manage policies and signatures, troubleshoot high-priority incidents, and help refine SOPs, TTPs, and system documentation. The ideal candidate brings a strong Linux administration background (preferably RHEL) along with exposure to or understanding of a SOC environment, as the team’s biggest need is strengthening its overall Linux expertise while continuing to evolve its security infrastructure.

This position is a hybrid role (60% onsite/40% remote) Compensation: $70.06/hr to $77.84/hr exact compensation may vary based on several factors, including skills, experience, and education.
