• Assess and harden OT/IoT devices against vulnerabilities, ensuring compliance with security policies.
• Evaluate and deploy specialized OT/IoT security solutions, including intrusion detection systems (IDS) and firewalls.
• Develop network segmentation strategies for industrial control systems (ICS) and ensure secure communication between IT and OT layers.
3. Industrial Automation and SCADA Systems
• Manage the security of SCADA systems, distributed control systems (DCS), and programmable logic controllers (PLCs).
• Work closely with engineers and operators to secure industrial automation processes without impacting operations.
• Lead initiatives to modernize legacy systems while mitigating security risks.
• Provide expertise in managing vendors and third-party solutions in manufacturing and industrial automation settings.
4. Threat Intelligence and Risk Management
• Analyze emerging threats specific to OT/IoT environments and implement proactive mitigation measures.
• Conduct risk assessments and vulnerability analyses across OT landscapes, including physical and cyber threats.
• Collaborate with IT security teams to integrate OT security strategies into enterprise-wide risk management.
5. Training and Awareness
• Deliver training programs for engineering teams, operators, and other stakeholders to enhance cybersecurity awareness in OT environments.
• Foster a culture of security within manufacturing and industrial teams, emphasizing the importance of securing critical infrastructure.

Qualifications

1. Education
• Bachelor s degree in Computer Science, Cybersecurity, Industrial Engineering, or a related field.
• Advanced certifications are a plus (e.g., CISSP, GICSP, CISM, or similar).
2. Experience
• Minimum 8 10 years of experience in OT/IoT security operations and incident response.
• Proven experience working in industrial automation or manufacturing verticals, including SCADA, DCS, and PLC systems.
3. Technical Skills
• Expertise in OT-specific technologies and protocols (e.g., Modbus, OPC, PROFINET, Ethernet/IP).
• Experience with tools like SIEM, IDS/IPS, and network monitoring solutions in OT settings.
• Familiarity with OT security frameworks (e.g., ISA/IEC 62443, NIST 800-82).
4. Soft Skills
• Strong leadership and communication skills to work effectively with diverse stakeholders.
• Ability to balance security priorities with operational requirements in a high-pressure environment.

  Preferred Certifications

  • GICSP (Global Industrial Cyber Security Professional)
  • CISSP-ISSAP (Information Systems Security Architecture Professional)
  • ISA/IEC 62443 Cybersecurity Certificate
  • Certified Incident Handler (GCIH)
