The successful candidate is responsible to coordinate delivery between IT security architects, implementation partners, and consuming teams. He/she will handle Cryptography Engineer function supporting the downstream Post-Quantum Cryptography (PQC) transition.

Responsibilities:

• Work closely with IT Security Architects (Cryptography and PKI), implementation partners (CLM, EKMS), CA/PKI operators, and application owners to implement and operationalize certificate and key management solutions using best-of-breed technology and methodology.

• Conduct requirement workshops with application teams and platform owners, analyze certificate and key management requirements holistically across on-premises and Cloud (AWS) estates.

• Contribute to, influence, and review the design of CLM and EKMS solutions to ensure they meet both security and operational needs; demonstrate technical depth in PKI, certificate lifecycle, and key management.

• Set up, improve, and streamline certificate and key management operational processes (issuance, renewal, revocation, discovery, rotation, escrow) for continuous improvement and to eliminate outage risk from expiry.

• Incorporate cryptographic and key management best practices (FIPS, NIST, X.509, PKCS) into operational workflows and platform configuration.

• Good understanding of the principles, key controls, and processes relating to cryptography, PKI, and key management (X.509, TLS/mTLS, PKCS standards, certificate authorities, key hierarchies, HSM-backed key protection).

• Hands-on experience in implementing or operating a Certificate Lifecycle Management platform (e.g. CyberArk Venafi, Keyfactor, Entrust) - discovery, policy, automated enrolment/renewal, CA integration.

• Hands-on experience with enterprise key management and/or HSMs (e.g. Entrust nShield, Thales CipherTrust, AWS KMS/CloudHSM), including Security World / key ceremony concepts.

• Experience in integrating security platforms with enterprise systems via REST APIs — e.g. ITSM (ServiceNow), IAM/SSO (PingOne), SIEM/observability (Splunk, Datadog), vulnerability scanning (Nessus).

• Experience and proficient in scripting/programming languages for automation — e.g. Python, PowerShell, and/or Bash.

• Good at working with detail and meticulous in operations; strong analytical skills and enjoys complex problem solving.
