Cryptographic Architect (Solution Architect)
This contract role focuses on enterprise cryptographic and security architecture, including migrations of certificate authorities into an Enterprise PKI and the development of post-quantum and crypto-agility strategies. The key requirements are strong cryptographic fundamentals, PKI and CA migration knowledge, key-management architecture with HSMs or KMS, security and protocol reviews, threat modelling, and cryptographic standards governance. A relevant technical degree and typically 5–12+ years of experience are specified; CISSP, CISM, or specialized security certifications are preferred. The role is based in Dublin, and the structured input specifies a contract; the work mode is not stated. The description says “typically 5 to 12+ years,” while the structured experience range is 5–12 years.
