• Ensure SOC has the right visibility: develop log collection strategies and validate data quality.
• Act as technical counterpart for SOC: review detection use cases, validate alerts, and recommend improvements.
• Investigate escalated incidents from SOC for deeper analysis and coordinate remediation with internal teams.
• Support compliance through audit-ready documentation and participation in risk assessments.
• Contribute to automation and integration initiatives to enhance detection and monitoring capabilities.

To be successful in the role, you need:

·       Technical Expertise: SIEM, EDR/XDR, SOAR, cloud security technologies.

·       Threat Detection & Analysis: Ability to design detection logic and leverage threat intelligence.
