• Establish secure processes for key ceremonies, delegated cold custody, staking deposits and withdrawals, and other critical digital-asset operations.

• Develop crypto-specific security standards, privileged-access controls, and secure SDLC requirements within a multi-account AWS environment.

• Partner with centralized Infrastructure Security, Application Security, IAM, and SOC teams to implement and maintain platform security capabilities.

• Define blockchain and custody-specific detection use cases for the SOC.

• Lead incident response procedures for crypto-specific scenarios, including key compromise, unauthorized transactions, and significant on-chain incidents, in collaboration with Corporate Security.

• Conduct detailed threat modeling and security reviews covering internal ledger mechanisms, balance idempotency, withdrawal sequencing, and smart contract integrations.

• Protect the integrity of transaction and funds flows across the platform by identifying and mitigating architectural and operational risks.

• Direct security assessments and ongoing assurance activities for external custody providers, execution systems, blockchain analytics solutions, Travel Rule tools, and treasury integrations.

• Map security controls to relevant international regulatory frameworks, including MiCA, DORA, FCA, and MAS requirements.

• Collaborate with market and regulatory teams to maintain appropriate security and compliance controls as the platform expands internationally.

• Translate complex cryptographic, infrastructure, and digital-asset risks into clear business and regulatory implications for non-security stakeholders.

• Strong cloud security expertise, preferably within AWS environments and regulated organizations.

• Practical experience mapping security controls to recognized frameworks and regulatory requirements, including ISO 27001, SOC 2, and NIST.

• Strong experience conducting threat modeling, security assessments, risk analysis, and incident response.

• Ability to communicate sophisticated cryptographic and technical security risks clearly to business leaders, product teams, engineers, compliance professionals, and regulators.

• Proven ability to operate effectively within a matrixed security organization and collaborate with dedicated IAM, AppSec, SOC, and Infrastructure Security functions.
