• Automation & Integrations: Create or maintain scripts (Python/PowerShell) for investigation support, enrichment, and workflow automation; help integrate telemetry sources into Elastic as needed.
• Customer Training & Enablement: Provide training to customer teams on SIEM usage, detection capabilities, investigation workflows, and security best practices to drive long-term operational success.
• Operational Excellence: Contribute to documentation (runbooks, detection standards, triage playbooks) and continuous improvement of SOC workflows.

Salary Range: $90,000 - $120,000
