The contractor will serve as a SIEM Engineer and must show extensive experience successfully designing, implementing, maintaining, and optimizing Palo Alto Cortex XSIAM and Cortex XDR in large-scale, multi-tenant security environments. This contractor will work with a large enterprise security team and a 24x7 Security Operations Center (SOC), assisting full-time security architects, engineers, and analysts with the design, implementation, integration, and continuous improvement of SIEM, XDR, detection, and response capabilities supporting multiple agencies. The contractor will be primarily focused on Cortex XSIAM and Cortex XDR engineering, administration, detection content, automation, and operational support while also providing important secondary support for Cribl data modeling, log pipeline design, parsing, normalization, enrichment, and ingestion. The role requires hands-on experience supporting both security engineering and SOC operations, including multi-tenant onboarding, tenant-specific configurations, access controls, data separation, integrations, dashboards, reporting, incident response, threat hunting, playbooks, runbooks, standard operating procedures, and analyst enablement. The candidate must be able to support strategic planning, solution design, implementation, troubleshooting, performance optimization, and continuous improvement of secure systems and services.
