System Security Engineer

. 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.

. Setup, 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.

. Monitor, analyze, investigate, and resolve day-to-day operational incidents relating to certificates, keys, and HSMs provide advisory to application teams.

. Manage and maintain strong vendor relationships (CyberArk, Agile Sec, Entrust n Shield) to ensure continuous support and knowledge transfer for current and future cryptographic needs.

. Play an active role in project coordination between internal resources and third parties/vendors for CLM and EKMS execution.

. Support the cryptographic asset discovery and inventory (CBOM) that underpins the PQC transition and prepare to take on the cryptography engineer role for hybrid-PQC piloting and migration.
