Job Overview:
We are seeking a highly skilled OT Cybersecurity Engineer to support our growing portfolio of industrial cybersecurity projects. The ideal candidate will have strong hands-on experience in conducting OT cybersecurity risk assessments, developing disaster recovery plans, and implementing security controls in operational technology environments including energy, oil & gas, and utilities.

This role will be part of a project delivery team responsible for assessment, design, implementation, testing, and commissioning of OT-CS controls in line with global standards (ISA/IEC 62443, NIST SP 800-82, etc.).

Key Responsibilities:
1. Assessment & Design

  • Conduct site-based OT cybersecurity risk assessments and gap analysis
  • Perform asset inventory mapping, network zoning, and data flow analysis
  • Identify vulnerabilities in OT environments (PLC/SCADA/DCS/RTU systems)
  • Develop risk treatment plans, cybersecurity roadmaps, and disaster recovery plans
  • Create network architecture diagrams and zoning segmentation designs
2. Implementation & Configuration

  • Configure and deploy OT firewalls, switches, and segmentation appliances (e.g., Fortinet, Juniper, Hirschmann, Cisco, Moxa)
  • Implement endpoint protection, application whitelisting, patching, and USB control solutions
  • Integrate and tune SIEM, IDS/IPS, and secure remote access platforms
  • Perform system backups, hardening, patch management, and monitoring setup
  • Coordinate with SOC/NOC teams to ensure proper monitoring, incident detection, and alert correlation for OT environments
  • Assist in integrating OT assets into existing SOC workflows and playbooks
  • Support commissioning, Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and go-live activities
3. Compliance & Documentation

  • Align assessments and implementations with global and regional standards: ISA/IEC 62443, NIST SP 800-82, ISO 27001, NCA ECC, and NESA
  • Develop comprehensive documentation: High-Level Designs (HLDs), Low-Level Designs (LLDs), FAT/SAT reports, Disaster Recovery and Business Continuity Plans, backup and restoration procedures
  • Deliver hands-on training sessions for customer teams on implemented controls
  • Support post-deployment SLA services, incident response, and system health checks
Requirements

  • Bachelor’s Degree in Engineering, Computer Science, or related field
  • Minimum 5 years of OT cybersecurity experience in industrial environments
  • Strong knowledge of ICS/SCADA/DCS platforms (e.g., Honeywell, Siemens, Schneider, Emerson)
  • Hands-on experience with industrial firewalls, SIEM, EDR, backup systems
  • Familiarity with OT protocols (Modbus, OPC, DNP3, IEC 61850, etc.)
  • Understanding of standards: ISA/IEC 62443, NIST SP 800-82, ISO 27001 (with OT alignment)
  • Experience with cloud security technologies (e.g., AWS, Azure) is considered a strong plus, especially in environments involving IT/OT integration or industrial digitalization.
  • Ability to work independently on customer sites and lead technical delivery activities
Preferred Certifications (any of the following):
  • GICSP, ISA/IEC 62443, CISSP, CRISC, CISM
  • CCNP Security, Fortinet NSE, CySA+, CEH, or equivalent
