## About the Role

* 12+ years of IT security or enterprise network engineering experience, including at least five years of hands-on network security engineering or assessment.
\n

 * Strong routing, switching, and network-protocol fundamentals, with practical expertise in enterprise firewalls, VPNs, segmentation, and secure connectivity across on-premises and AWS/hybrid environments.
\n

 * Demonstrated working knowledge of applied cryptography in networking: TLS 1.2/1.3, IPsec/IKEv2, SSH, PKI and certificate lifecycle, key management, and FIPS-validated cryptographic modules.
\n

 * Familiarity with the NIST PQC standards (FIPS 203, 204, and 205) and the Federal PQC migration landscape, including NSM-10, OMB M-23-02, NIST transition guidance (NIST IR 8547), and applicable Executive Order requirements.
\n

 * Experience assessing network security against Federal frameworks and standards such as NIST SP 800-53 (e.g., SC-8, SC-12, SC-13), SP 800-52, SP 800-77, and DISA STIGs or CIS Benchmarks.
\n

 * Ability to analyze device configurations, packet captures, and scan output (e.g., Wireshark, Nmap, testssl.sh/sslscan) to verify cryptographic and security settings.
\n

 * Strong technical writing and customer communication skills.
\n, * Experience supporting Federal Government enterprise networks, preferably at a civilian agency.
\n

 * Experience with cryptographic discovery and inventory tools or automated cryptographic asset management.
\n

 * Hands-on lab testing of PQC or hybrid key exchange (e.g., OpenSSL 3.5 or Open Quantum Safe libraries; hybrid TLS or IKEv2 with ML-KEM).
\n

 * Depth in a complementary specialty: network access control and identity integration, application-delivery security (e.g., F5/WAF), or HSM and enterprise key management.
\n

 * Relevant certifications such as CISSP, CCNP/CCIE Security, GIAC (e.g., GCIA), or CompTIA SecurityX (formerly CASP+). Certifications do not replace demonstrated assessment experience.
