About The Position

Join the Classified Network Operations Team supporting DevSecOps initiatives across Lockheed Martin Aeronautics’ high-impact programs. This position is integral to the secure deployment, maintenance, and automation of classified network infrastructure, ensuring compliance, resilience, and agility within a fast-paced, mission-critical environment. You will work hands-on to integrate security into every phase of the network lifecycle—from design and development to operations and monitoring—supporting Lockheed Martin’s strategic platforms including Advanced Development Programs (ADP), F-22, and JSF. Serve as a DevSecOps engineer with a focus on secure network infrastructure, automating provisioning, compliance checks, and incident response across classified environments. Maintain and secure network hardware, including Cisco switches, Palo Alto and Juniper firewalls, and Type 1 encryption devices. Implement infrastructure as code (IaC) where applicable, and integrate network configuration management into CI/CD pipelines to support rapid, repeatable deployments. Utilize and secure tools like Cisco ISE, DNA Center, and Call Manager, ensuring consistent security policies and monitoring. Collaborate across cyber, development, and operations teams to embed security practices throughout the system lifecycle. Support network vulnerability management, remediation efforts, and compliance with DoD cybersecurity standards (e.g., STIGs, RMF). Participate in planned infrastructure upgrades, including installation and structured cabling of network components in classified environments. Apply continuous monitoring and log analysis to identify anomalies, enforce security baselines, and improve operational visibility
