Role Overview

Seeking a Post-Quantum Cryptography (PQC) Engineer to design, implement, and integrate quantum-resistant cryptographic solutions.

Help strengthen cybersecurity infrastructure and prepare enterprise systems for emerging threats posed by quantum computing.

Key Responsibilities

  • Design, develop, and implement post-quantum cryptographic solutions.
  • Work with NIST-standardized PQC algorithms, including ML-KEM (Kyber), ML-DSA (Dilithium), and SLH-DSA (SPHINCS+).
  • Assess existing cryptographic systems and support PQC migration and modernization strategies.
  • Integrate quantum-resistant cryptography into PKI, TLS, VPNs, and secure communication systems.
  • Conduct cryptographic testing, performance benchmarking, and interoperability assessments.
  • Support hybrid cryptography implementations and cryptographic agility.
  • Develop technical documentation, implementation guidelines, and security recommendations.

Requirements

  • Bachelor's degree in Computer Science, Cybersecurity, Mathematics, or a related field.
  • Strong understanding of cryptography, encryption, digital signatures, and key management.
  • Hands-on experience with post-quantum cryptographic algorithms, libraries, or implementations.
  • Knowledge of PKI, TLS, OpenSSL, and cryptographic protocols.
  • Programming experience in Python, C/C++, Rust, or similar languages.
  • Strong analytical, troubleshooting, and problem-solving skills.

Preferred Qualifications

  • Experience with NIST post-quantum cryptography standards and migration frameworks.
  • Familiarity with Open Quantum Safe (OQS) libraries or similar PQC implementations.
  • Experience integrating cryptographic solutions into enterprise security infrastructure.
