This is one of the most technically distinct roles in the organisation. The mandate is to replace assumption-based compliance with cryptographic proof — designing systems where regulators, auditors, and counterparties don't have to take the platform's word for it. Don't trust us, verify us is the design philosophy. Your job is to make that a technical reality.

You will own the global cryptographic architecture for cross-border payment systems — including Key Management Systems , key sovereignty, encryption standards across data at rest, in transit, and in use, and tamper-proof logging and immutable audit trails .
