ABOUT THE ROLE

• Engineer, tune, and support Microsoft Defender capabilities, including Defender for Endpoint and Defender for Cloud Apps, with a focus on scalable enterprise deployment.
• Partner with endpoint engineering to align device posture, compliance signals, and Defender telemetry with Conditional Access and Zero Trust objectives.
• Improve detection fidelity, reduce false positives, and strengthen operational readiness through repeatable engineering standards and control validation.
• Collaborate with Security Operations on incident response, threat hunting, and continuous improvement of endpoint and cloud threat protections.

Data Protection (Purview)

• Design, implement, and manage Microsoft Purview capabilities, including Data Loss Prevention, sensitivity labeling, classification, Insider Risk, and eDiscovery.
• Translate business and compliance requirements into scalable technical controls that support governance, data handling standards, and secure collaboration.
• Develop and maintain policy-aligned protection standards for sensitive information across Microsoft 365 workloads.
• Partner with stakeholders to validate control effectiveness, support investigations, and continuously improve information protection maturity.

Identity Security

• Support and help operationalize identity security controls, including Conditional Access, MFA/passwordless strategies, Privileged Identity Management, and secure access governance.
• Partner on lifecycle-oriented identity standards that improve authentication strength, reduce administrative risk, and support least-privilege access.
• Ensure engineering decisions align with Zero Trust architecture, enterprise security baselines, and broader Digital Workspace standards.

Operational Excellence & Collaboration

• • Contribute to operational metrics, service improvements, and platform maturity initiatives across Microsoft 365 security services.
  • Document engineering standards, technical decisions, implementation guidance, and supportable operational procedures.
  • Partner across Digital Workspace, Security, Infrastructure, and service providers to improve reliability, policy enforcement, and control effectiveness.
  • Support continuous improvement through automation, standardization, and repeatable engineering practices.
