• Troubleshoot incidents, perform root cause analysis, and implement durable remediation.
• Maintain system documentation, architecture diagrams, and security procedures.

Identity, Access & Compliance

• Implement and enforce least-privilege principles using AWS IAM, SSO, and identity integrations.
• Automate permission audits and cloud security posture monitoring.
• Support compliance with frameworks such as SOC 2, HIPAA, PCI-DSS, and ISO 27001.
