- Configure specified Microsoft Entra controls for agents, including Conditional Access, Identity Protection, entitlement management, access packages, access reviews, or lifecycle workflows when included in the approved design.
- Configure and validate specified Microsoft Purview controls for agents and AI applications, including sensitivity labels, Data Loss Prevention, audit, and related data protection policies when included in scope.
- Configure and validate specified Microsoft Defender capabilities for agent security posture, threat detection, investigation, and response when included in scope.
- Support configuration and validation of applicable Microsoft Intune and Microsoft 365 administrative controls.
- Execute defined pilot scenarios, test cases, and acceptance criteria, and capture clear implementation and validation evidence.
- Review agent sign-ins, audited activities, telemetry, dashboards, alerts, and other operational data required by the approved test plan.
- Troubleshoot configuration, integration, permission, onboarding, and policy-enforcement issues.
- Escalate architecture decisions, ambiguous requirements, scope questions, product limitations, and material delivery risks to the solution architect and Project Manager.
- Develop accurate as-built documentation, configuration records, test results, administrator procedures, support procedures, and operational runbooks.
- Provide technical demonstrations and knowledge transfer to customer administrators, security operations personnel, and support teams.
- Provide technical guidance to supporting engineers while remaining accountable for the quality of assigned implementation work.
