• Utilize the SIEM and EDR platform extensively, applying expert knowledge of scripting, SIEM and EDR query language to perform complex searches and data analysis.
• Lead and participate in incident response activities, including containment, eradication, and recovery efforts, serving as a primary escalation point for critical security incidents.
• Develop and refine threat hunting playbooks, procedures, and detection rules to improve the security team’s efficiency and effectiveness.
• Collaborate with the security engineering and security operations center (SOC) teams to integrate new threat intelligence and enhance existing security tools and controls.
• Mentor junior analysts and contribute to the ongoing improvement of the organization’s overall security posture.

• Hands‑on experience using EDR (Endpoint Detection and Response) and threat hunting platforms.
• Expert-level knowledge of PowerShell scripting, Python, and EDR/ SIEM query languages.
• Deep understanding of incident response lifecycles, methodologies, and forensic techniques.
• Strong knowledge of networking protocols, operating systems (Windows, Linux, macOS), and common attack vectors.
• Familiarity with scripting languages (e.g., Python, PowerShell) for automation of hunting tasks.
• Exceptional analytical and problem‑solving skills with keen attention to detail, and ability to work independently with minimal supervision while managing multiple investigations simultaneously.
• Strong communication skills, capable of presenting complex technical information clearly to both technical and non‑technical audiences.
• A proactive mindset and passion for continuous learning in the rapidly evolving field of cybersecurity.
