Solid grasp of Kubernetes RBAC entities—Role, Cluster Role, Role Binding, ClusterRoleBinding—and how they map to Kubernetes API groups

Familiarity with Single Sign-On (SSO) protocols (SAML, OAuth 2.0/OIDC) and identity providers (Azure AD, GCDS, AWS IAM)
Understanding of SCIM provisioning, user lifecycle workflows (onboarding/offboarding), and entitlement catalogue management for major SaaS (e.g., Office 365)

Proven track record analysing SaaS-based identity integrations (e.g., SAML SSO, SCIM provisioning)
