Responsibilities

• Own workload identity and secrets management: SPIRE/ODIS, Keycloak/Entra ID (IAM), OpenBao (secrets store), cert-manager (X.509 lifecycle) across environments.
• Build confidential compute environments: TDX/SEV-SNP/SGX/TrustZone/DOCA, secure boot, attestation-ready.
• Establish platform-wide identity model for workloads, agents, and services across telemetry and policy.
• Own cryptographic lifecycle: certificates, keys, roots rotation and revocation with no secret sprawl.
• Enforce attestation policy: which nodes/enclaves/workloads are trusted and how proof is captured for audit.
• Partner with Enterprise Security/Cloud Platform/SRE for audit readiness in regulated contexts.
