Integrate SAST and DAST tooling into CI/CD pipelines; triage findings, define severity thresholds, and partner with developers to close vulnerabilities prior to production release.
Own the RBAC governance process: design role models, conduct periodic access reviews, enforce least-privilege principles, and document role assignments across Azure and application layers.
Collaborate with DevOps and Platform Engineering teams to embed security controls (secrets management, image scanning, policy-as-code) into DevOps pipelines and IaC workflows (Terraform, Ansible).
