• Deep, practical knowledge of authorisation models: relationship-based access control (ReBAC), role-based (RBAC), and attribute-based (ABAC), and knowing when to apply each
• Experience designing authorisation schemas and permission models, and reasoning about correctness, latency, and consistency at scale
• Familiarity with policy-as-code approaches and tooling (OPA / Rego, Cedar, or equivalent)
• Understanding of the operational side: running the authorisation engine in production, backed by PostgreSQL, with observability and traceability of authorisation decisions
• Architecting and engineering enterprise-scale AuthN solutions, demonstrated at production scale
• Hands-on production experience with Curity and/or Keycloak: configuration, customisation, operations, and integration
• Deep, practical knowledge of OAuth 2.0, OpenID Connect (OIDC), SAML 2.0, and token-based authentication patterns (JWT, opaque tokens, token introspection)
• Experience with enterprise identity federation, SSO, and directory integration (LDAP, Active Directory)
• Strong hands-on engineering capability across the NGA stack, or the ability to get there fast:
• Backend: Go
• Messaging / Streaming: Apache Kafka / RedPanda
• Data: PostgreSQL
• Comfortable operating in a cloud-native environment: Kubernetes (AKS), containers, GitOps, Infrastructure as Code
• Event-driven and distributed systems architecture
• Secure coding practices and security-by-design principles
