Senior Cybersecurity SME – Cryptography & Post-Quantum Cryptography (PQC)

Location: Irving, TX
Work Arrangement: On-site at Client Facility
Interview: Face-to-Face (F2F) in Irving, TX – Mandatory

Job Overview

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.

Key Responsibilities

• 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• Identify outdated encryption protocols, weak cipher suites, and vulnerable cryptographic algorithms.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.

Required Technical Skills

• 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.

Important Requirements

• 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.
