Senior Specialist: Cybersecurity Analyst

**ROLE PURPOSE**

As part of the Customer-facing Nexio SOC team, the Senior Specialist: Cybersecurity Analyst plays a critical role in monitoring, detecting, and responding to cybersecurity incidents within a Security Operations Center. The Cybersecurity Analyst utilizes incident handling methodologies to validate security events, assess severity levels, and provide guidance to SOC Analysts. By leveraging threat intelligence and conducting in-depth analysis, Cybersecurity Analyst identifies the scope of attacks, impacted systems, and potential perpetrators. The Cybersecurity Analyst ensures shift-related metrics are monitored, offers recommendations, and advises on containment and recovery steps. The Cybersecurity Analyst documents incidents, updates relevant documentation and supports the development of analytic methods for threat detection.

He/She should ideally have advanced security incident handling analysis experience in an established SOC environment and contribute to risk management, lead Blue Team exercises, mentor junior analysts, and develop playbooks for incident scenarios. The Cybersecurity Analyst monitors network traffic, investigates incidents, and collaborates with the SOC team to respond to threats or intrusions.
