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 a
