Job summary

Accenture Middle East seeks an OT SOC L3 Analyst to act as the senior technical authority for OT security, threat hunting, DFIR, and detection engineering across OT/ICS environments. The role leads complex incident responses and mentors L1-L2 analysts while shaping OT defense capabilities.

The analyst translates OT threat intelligence into detections, defines playbooks, and collaborates with engineering to harden networks, monitors OT platforms, and coordinates with regulators.

Qualifications

• Bachelor's degree in Cybersecurity or related field (Master's a plus).
• 6–10+ years of cybersecurity experience, with at least 4 years in OT/ICS security operations, DFIR or threat hunting.
• Deep expertise in OT protocols and ICS architectures (DCS, SCADA, PLC, SIS) and the Purdue model.
• Proven experience leading OT/ICS incident response and forensic investigations.
• Strong command of OT monitoring platforms (Nozomi, Claroty, Dragos, Tenable OT, Defender for IoT) and SIEM detection engineering (Splunk, QRadar, Sentinel).
• Advanced working knowledge of MITRE ATT&CK for ICS, NIST SP 800-82, ISA/IEC 62443 and NCA OTCC.
• Preferred certifications GRID, GCIP, GICSP, GCFA or GREM (GIAC).
• Vendor expert-level certifications (Dragos, Claroty, Nozomi).
• Expert analytical, forensic, and reverse-engineering/malware-analysis aptitude in an OT context.

Responsibilities

• Lead investigation and response for complex high-severity OT/ICS incidents.
• Perform threat hunting across OT networks and assets; design and run hunt campaigns.
• Conduct OT-aware DFIR, forensic acquisition and analysis of ICS hosts and HMIs while preserving safety and evidence integrity.
• Design, build and tune detection content; own the detection engineering lifecycle for the OT SOC.
• Operationalize OT threat intelligence and map to detections via MITRE ATT&CK for ICS.
• Define and improve OT incident-response playbooks and runbooks.
• Mentor L1/L2 analysts; provide coaching and quality review of investigations.
• Lead OT tabletop exercises and purple team activities.
• Advise on OT network architecture segmentation and monitoring placement.
• Produce executive and technical incident reports; brief stakeholders on root cause and remediation.
• Support compliance audits and regulatory reporting aligned to OT standards.
