Job Description
Scope
This position will serve as a SIEM engineer. The successful candidate will 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 state agencies.
Successful Candidate
This 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.
