• Advanced certifications are strongly desired, such as CySA+, CEH, OSCP, GICSP, CCNA Security, or relevant OT security certifications such as ISA/IEC 62443.
• Deep understanding of cybersecurity fundamentals, including TCP/IP, UDP, DNS, Windows and Linux operating systems, and security architecture principles.
• Strong knowledge of OT protocols such as DNP3, Modbus, IEC 104, and OPC UA, including packet analysis and protocol vulnerabilities.
• Experience with SIEM, SOAR, IIDS/IPS, endpoint detection solutions, and network traffic analysis tools.
• Strong analytical skills and attention to detail, including the ability to interpret complex data, identify patterns, and draw conclusions.
• Excellent verbal and written communication skills, including the ability to explain technical information to varied audiences and prepare clear reports.
• Demonstrated ability to lead and mentor junior analysts.

• Develop, test, and implement custom detection rules, correlation searches, baseline-drift detections, and use cases tailored to OT protocols and environments.
• Proactively hunt for indicators of compromise and misconfigurations in OT environments using threat intelligence, anomaly detection, and knowledge of ICS/SCADA attacker tactics, techniques, and procedures.
• Create and maintain incident response playbooks, standard operating procedures, and runbooks, incorporating lessons learned, threat intelligence, and industry practices.
• Document incident-handling actions, findings, and decisions in the SOC ticketing system and prepare concise management reports.
• Guide, train, and mentor Tier 1 and Tier 2 analysts in incident handling, analysis, tools, and OT security concepts.
• Participate in training and simulations to stay current on cyber threats, OT security practices, and monitoring tools.
• Keep current with NERC-CIP standards, particularly levels 2 and 3, NIST CSF, the Client Model for Industrial Control Systems, ISO 27001, and other relevant OT security regulations.
