Post-Quantum Cryptography (PQC) / Crypto Security Architect

Post-Quantum Cryptography (PQC) / Crypto Security Architect

Job Location: Bangalore / Pune

Experience: 10+ Years

Employment Type: Full Time

Job Summary

We are looking for an experienced Cryptography / Cyber Security Architect with strong expertise in enterprise cryptographic controls and emerging Post-Quantum Cryptography (PQC) standards. The role will focus on assessing quantum-related risks, defining crypto-agile architectures and developing practical migration roadmaps for enterprise and regulated environments.

The ideal candidate should have a strong foundation in RSA, ECC, PKI, X.509, TLS/SSL, SSH, IPsec, digital signatures, HSM/KMS and hands-on understanding of NIST PQC algorithms and hybrid cryptographic migration patterns.

Key Responsibilities

• Assess enterprise cryptographic environments and identify quantum-related risks and vulnerabilities.
• Develop crypto-agility reference architectures and hybrid cryptographic design patterns.
• Define prioritized Post-Quantum Cryptography migration roadmaps aligned with business and technology priorities.
• Provide expertise across PKI, certificates, digital signatures, HSM, KMS and enterprise cryptographic controls.
• Evaluate existing cryptographic implementations and recommend modernization approaches.
• Develop risk-scoring models, architecture assessments and technical recommendations.
• Conduct client workshops and communicate complex cryptographic concepts to technical and senior stakeholders.
• Create executive-ready technical narratives, architecture documents and assurance notes.
• Support security architecture, threat modeling and cloud security initiatives.

Required Skills

• Strong understanding of RSA, ECC, PKI, X.509, TLS/SSL, SSH, IPsec and digital signatures.
• Strong knowledge of certificate lifecycle management, HSM and KMS concepts.
• Hands-on familiarity with security architecture, threat modeling, cloud security and enterprise cryptographic controls.
• Working knowledge of NIST Post-Quantum Cryptography (PQC) standards.
• Knowledge of ML-KEM / Kyber, ML-DSA / Dilithium and SLH-DSA / SPHINCS+.
• Understanding of hybrid cryptography and PQC migration patterns.
• Ability to create reference architectures, migration roadmaps and risk-scoring models.
• Strong stakeholder management, consulting and communication skills.

Good to Have

• Experience in BFSI, banking, payments, regulated workloads, identity platforms or high-value data protection environments.
• Exposure to OpenSSL, liboqs, PQClean, Bouncy Castle and PKCS#11.
• Experience with cloud KMS/HSM platforms and cryptographic tooling.
• Familiarity with NIST, FIPS, ETSI and CNSA 2.0 standards.
• Understanding of sector-specific regulatory and security requirements.

Key Deliverables

• Quantum-risk assessment approach
• Crypto-agility reference architecture
• Hybrid cryptographic design patterns
• Prioritized PQC migration roadmap
• Client workshop outputs
• Architecture assurance and technical assessment notes

Candidate Profile

We are looking for someone who can combine deep cryptography/security knowledge with architecture and consulting skills. Candidates should be comfortable working with technical teams as well as senior business/client stakeholders and translating complex cryptographic risks into clear, actionable migration strategies.
