Role Summary:

Key Responsibilities

• Lead the design, engineering, deployment, and continuous improvement of enterprise security tools and platforms, including EDR, SIEM, IDS/IPS, MDM, and Microsoft 365 security solutions.
• Architect and implement scalable security controls to protect endpoints, networks, cloud workloads, identity systems, and business-critical infrastructure.
• Manage and optimize integrations across security platforms, including EDR, SIEM, SOAR, MDM, IAM, and related monitoring tools.
• Drive incident detection and response engineering through alert tuning, detection use case development, correlation logic, and automation playbooks.
• Oversee deployment and enforcement of endpoint security controls, including DLP, USB/device control, device compliance policies, and endpoint hardening standards.
• Collaborate with SOC, Infrastructure, IAM, Cloud, and application teams to ensure security controls are implemented, monitored, and operationalized effectively.
• Lead troubleshooting and root cause analysis for security events, tool failures, policy issues, log ingestion gaps, and control effectiveness concerns.
• Establish and maintain SIEM use cases, correlation rules, dashboards, reports, and operational metrics to improve monitoring and executive visibility.
• Conduct vulnerability assessments, validate scan results, support remediation planning, and track risk reduction activities through closure.
• Participate in change management processes to assess security impact, define control requirements, and ensure security tooling remains aligned with approved changes.
• Drive automation initiatives using PowerShell, Python, SOAR workflows, and other scripting methods to reduce manual effort and improve response consistency.
• Develop and maintain security baselines, hardening standards, deployment playbooks, operational guides, and technical documentation.
• Monitor emerging threats, threat intelligence, and adversary techniques to adapt detections and controls based on current attack trends.
• Provide technical leadership, coaching, and mentorship to junior engineers, SOC analysts, and cross-functional teams.

Technical Responsibilities

• Engineer, deploy, and administer EDR platforms such as CrowdStrike and Microsoft Defender for Endpoint, including policy tuning, threat detection, response actions, and control validation.
• Implement and manage SIEM platforms such as CrowdStrike NG SIEM or Splunk, including log onboarding, parsing, normalization, dashboarding, and advanced correlation logic.
• Design, implement, and support IDS/IPS and network security monitoring solutions to improve threat visibility, prevention, and investigation capability.
