• Lead multi-tenant agency onboarding, tenant-specific configurations, role-based access controls (RBAC), and logical data segregation.
• Design, configure, and maintain operational dashboards, alert telemetry, and compliance reporting tools for multiple agencies.

Detection Engineering & Automation

• Develop, test, and tune high-fidelity detections, correlation rules, threat-hunting queries, watchlists, and false-positive suppression logic.
• Create, test, deploy, and maintain automated response playbooks, workflows, and integrations using scripting languages (such as Python and Bash) to streamline incident enrichment, containment, and triage.
• Support Tier 1 through Tier 3 SOC analysts and incident responders through system troubleshooting, platform tuning, and knowledge transfers.

Log Management & Data Pipeline Optimization

• Plan, design, deploy, and support log management pipelines utilizing Cribl for data modeling, routing, parsing, normalization, and enrichment.
• Onboard and monitor the ingestion health of cloud, endpoint, network, identity, SaaS, Linux, Windows, and custom application telemetry sources.
• Optimize log ingestion volumes, retention policies, and platform performance to align with strict compliance requirements and cost-efficiency goals.

Governance, Documentation, & Compliance

• Author and maintain operational runbooks, Standard Operating Procedures (SOPs), escalation matrices, architecture diagrams, and analyst knowledge articles.
• Ensure high availability, platform resilience, automated backups, disaster recovery readiness, and controlled change management processes for SIEM and log services.
