Integrate endpoint telemetry into the central analytics platform or (SIEM) to support security context and cross-domain correlation; ensure SIEM coverage is adequate and effective. Serve as a technical escalation point for endpoint-based security events, exposures, vulnerabilities, and alerts; collaborate cross-functionally to drive remediation within appropriate SLAs. Investigate complex endpoint-based alerts and incidents through to root cause: perform triage, forensic artifact collection (memory, disk, logs), timeline reconstruction, and containment/eradication actions. Identity Security & Access Lead the design, deployment, integration, and optimization of identity security controls across workforce, privileged, service, and machine identities. Engineer and maintain capabilities for identity governance and administration, single sign-on, multi-factor authentication, conditional access, privileged access management, just-in-time access, secrets management, and identity threat detection and response. Design and enforce least-privilege access patterns, role-based and attribute-based access controls, segregation of duties, and lifecycle controls for joiner, mover, and leaver events. Integrate identity, authentication, authorization, and privileged-access telemetry into central analytics and SIEM platforms to enable cross-domain correlation, detection, investigation, and automated response. Serve as a technical escalation point for identity-based attacks, anomalous access, credential compromise, privilege misuse, and authorization failures; lead root-cause analysis and coordinated remediation. Automate identity and access provisioning, certification, policy enforcement, control validation, and response through APIs, scripting, workflow orchestration, and policy-as-code practices. Partner with IAM, IT, Security, Engineering, and application owners to embed secure identity patterns, remediate access risks, and improve the adoption and usability of identity controls. Define and monitor identity-security measures such as authentication coverage, privileged-access reduction, access-review completion, policy compliance, identity-control health, detection efficacy, and remediation performance. Layered Defense/Defense in Depth Lead the design, deployment and optimization security controls spanning perimeter, network, host, application, identity and data layers, ensuring and maintaining effectiveness of controls at each layer. Contribute to and enforce security control standards and design patterns aligned to industry-recognized frameworks, serving as a subject matter expert during implementation and review. Validate that telemetry from each layer feeds the central analytics platforms and supports 360-degree visibility and appropriate attack surface coverage. Continuously assess effectiveness of enterprise security controls as the ecosystem expands and the threat landscape evolves; propose and implement supplemental or extended coverage. Proactively partner with IT, Engineering and other stakeholders to embed security controls natively, serving as a technical lead on cross-functional initiatives. Provide technical recommendations on security control design aligned to vulnerabilities, risks, issues, and events; support lead-level decisions with well-documented analysis. Lead purple-team exercises and control-efficacy testing to verify depth and resilience under attack conditions. Ensure redundant, complementary security capabilities to prevent bypasses and ensure failure redundancy through all security layers. Threat Hunting Lead structured threat hunting engagements and purple team exercises in partnership with the Purple Team, analyzing security telemetry to surface anomalous and malicious behavior and communicating findings to relevant stakeholders. Develop, execute and document structured hunts mapped to MITRE ATT&CK and ATLAS techniques and current threat intelligence. Perform exposure analysis on identified vulnerabilities, zero-day, alert telemetry, threat intelligence feeds and notifications from partners and customers and conclude on exploitability risk and/or exposure.
