We are looking for a technically strong, motivated SOC Analyst to join a follow-the-sun security operations team. This is a hands-on role covering continuous monitoring, alert triage, incident investigation, threat analysis, incident response support, remediation coordination, documentation, and ongoing improvement of detection and response capability.
We operate a tierless SOC model — analysts own the full security operations lifecycle, from initial alert review and triage through investigation, containment support, escalation, documentation, closure, and improvement recommendations.
The primary platform is CrowdStrike Falcon Next-Gen SIEM. Analysts should be comfortable querying and analyzing security data, interpreting detections, correlating events across data sources, assessing suspicious or malicious activity, contributing to investigations, using dashboards and case management tools, and producing clear reporting.
