Location: Irving, TX
Work Arrangement: On-site at Client Facility
Interview: Face-to-Face (F2F) in Irving, TX – Mandatory
We are seeking a Senior Cybersecurity Subject Matter Expert with strong hands-on experience in enterprise cryptography, encryption technologies, and Post-Quantum Cryptography (PQC).
The candidate will assess cryptographic vulnerabilities across approximately 128 enterprise applications, analyze CBOM/SBOM security data, and recommend modernization strategies to strengthen encryption standards and prepare applications for quantum-resistant security.
Analyze JSON, SBOM, and CBOM security scan reports using tools such as Sonatype and CBOM Kit.
Identify outdated encryption protocols, weak cipher suites, and vulnerable cryptographic algorithms.
Recommend migration from TLS 1.0/1.2 to TLS 1.3 and weak ciphers to AES-256-GCM.
Assess SSH host keys, IKEv2/IPsec, encryption standards, and enterprise key management.
Evaluate legacy applications and infrastructure limitations affecting cryptographic modernization.
Identify common vulnerability patterns and develop technical remediation guidelines.
Support Post-Quantum Cryptography (PQC) readiness, including ML-KEM, ML-DSA, and hybrid TLS implementations.
Collaborate with AI engineering teams by providing sanitized technical remediation patterns without exporting proprietary security data.
Strong hands-on experience in Cybersecurity and Cryptography.
Expert knowledge of TLS 1.3, AES-256/AES-256-GCM, IKEv2, and IPsec.
Knowledge of Post-Quantum Cryptography (PQC), ML-KEM, and ML-DSA.
Experience analyzing CBOM, SBOM, JSON, and cryptographic security scan data.
Understanding of PKI, SSH keys, encryption algorithms, and key management.
Experience with enterprise security architecture and legacy application modernization.
Strong analytical skills and ability to translate security findings into technical remediation strategies.
Must be available to work on-site at the client facility.
Must be willing and able to attend a face-to-face interview in Irving, TX.
Must be comfortable working in a highly secure environment with strict data confidentiality and zero-data-export policies.
Must successfully complete client security onboarding requirements.
Candidates must have strong practical cryptography and encryption expertise. General cybersecurity experience alone will not be sufficient.
