Network Security Engineer

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 EIDS Network Engineer will support the FAA Enterprise Information Display System, providing expert-level security engineering across the enterprise. 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.
• 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.
• Perform integration, interoperability, maintenance, degraded operations, and technology refresh testing for NAS systems.
• Support IP addressing, network configurations, and data-flow documentation through IPSFs.
• Troubleshoot network connectivity, configuration, and interoperability issues.

• Bachelor’s degree in Cybersecurity, Information Technology, Telecommunications, or a related field.
• 6+ years of experience in cybersecurity or network security roles
• 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).
• 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.
• U.S Citizen or Green Card Permanent Resident (3+ years U.S. Residency)
• Ability to obtain FAA Public Trust
• Must be able to travel on occasion when needed.

• CISSP, Security+, CCNA, or similar certification.
• FAA or transportation sector experience preferred.
• Familiarity with Zero Trust Architecture, Security Orchestration, and network virtualization (e.g., NFV).
• Strong written, verbal, and interpersonal skills.
