Network Security Engineer (Multiple Levels)

Responsibilities We are looking for highly technical professionals with a strong foundation in network architecture, design, and security — individuals who are ready to step up from traditional network engineering roles to take ownership of strategic, architecture-level responsibilities. Ideal candidates will have deep understanding of networking, security architecture and design, and experience applying Federal security guidelines (e.g, NIST 800-53, FISMA, etc.) to harden and secure systems. These are the types of professionals who understand both the big-picture architecture and the hands-on technical details, and who are prepared to make security-focused architectural recommendations in complex environments. The TIS Security Engineer will support the FAA Telecommunications and Integrated Services (TIS) Group and provide expert-level security engineering across the FAA’s FTI environment. This includes: Analyzing and guiding network architecture to ensure cybersecurity is built-in from the ground up. Performing hands-on reviews of system configurations, firewall rules, and network paths to align with FAA Orders, NIST 800-53, and federal cybersecurity standards. Leading efforts in transitioning technologies (e.g., IPv4 to IPv6, microwave radio refreshes) from a cybersecurity and network architecture perspective. Supporting the integration of Zero Trust, Software-Defined Networking (SDN), and defense-in-depth strategies into enterprise-level solutions. Acting as a technical bridge between FAA cyber stakeholders and infrastructure providers (network, security, cloud). Evaluating vendor-proposed architectures and making expert-level recommendations based on federal policy, security principles, and industry best practices. Required Qualifications Experience supporting federal government programs, ideally within the FAA or transportation sector. Proven experience with hands-on network engineering or architecture and understands boundary protection design, configurations, firewalls, VPNs, IDS/IPS, and load balancing. Knowledge of telecommunications infrastructure, including IPv4/IPv6, and WAN/LAN environments. Understand federal cybersecurity frameworks (NIST RMF, FISMA, NIST SP 800-53 rev 5). Can evaluate network and system security concepts for large-scale, safety-critical systems like those in the National Airspace System (NAS). Comfortable advising on defense-in-depth architectures, Zero Trust CONOPS, SD-WANs, and emerging technologies. Have experience collaborating with System Engineers, Program Managers, and cybersecurity stakeholders to support ATO packages and continuous monitoring. Ability to develop system security plans, risk assessments, and related security documentation.
