Overview
In this role you design and build the Key Management Service to securely generate and rotate keys, enabling high-performance cryptographic operations. You implement complex data flows like Envelope Encryption and manage DEK-KEK relationships for layered security. You develop Kubernetes operators to automate KMS and Secrets Manager lifecycles and expose robust REST APIs for key management and signing workflows. You own the software lifecycle in an You Build It – You Run It environment, aligning security engineering with SRE. You ensure standards-compliant crypto operations and auditable trails to support sovereign cloud requirements.
