8. Coordinate with Tier 3 Analysts and management to refine detection and response workflows, contributing to SOC maturity.
9. Collaborate on tuning SIEM and detection tools to reduce false positives, submitting tuning requests and testing configurations as needed.
10. Identify gaps in detection content and work with Senior Analysts to develop and validate new detection rules and use cases tailored to organizational threats.
11. Mentor Tier 1 Analysts, offering guidance on triage and analysis techniques, and facilitate on-the-job training to elevate their skills.
12. Assist in training sessions and knowledge-sharing activities, providing feedback on areas for growth and fostering a supportive learning environment within the SOC.

Experience required:

• Understanding of advanced networking concepts, including IP addressing, network protocols, and traffic flow within networks.
• Proficiency in Windows and Linux operating environments, including commands, file systems, and authentication mechanisms.

• Knowledge of OSINT techniques for threat identification and information gathering.
• Effective communication skills for internal and external stakeholders, with the ability to explain technical issues clearly.
• Ability to produce concise, structured reports on investigations and monitoring activities.
• Strong workload management skills to ensure timely task completion.
• Willingness to collaborate, accept guidance, and learn from more experienced analysts.
• Initiative in learning new technologies and techniques, leveraging training resources.
• Ability to perform efficiently under high-pressure situations, following procedures to ensure consistent incident management.
