Establish and enforce platform security posture: secrets management via CyberArk/Conjur, RBAC, mTLS, compliance boundary design, and zero inbound telemetry architecture. Build and integrate ITSM capabilities for various platforms e.g automated incident creation, CI enrichment, and CMDB correlation. Define and implement extensibility patterns including AIOps: e.g anomaly detection hooks, event correlation pipeline design, and integration with future ML/AI tooling. Partner with other IT and business teams for App Dev, requirements capture, delivery validation and integration needs.
