Senior Engineer - OT Cybersecurity

Overview We are seeking highly skilled Engineers / / Senior Engineer / Lead Engineer to support the implementation of OT Cybersecurity solutions across utility environment and master control centers. The role involves hands-on deployment, configuration, and integration of cybersecurity technologies, infrastructure design, commissioning, and documentation. Candidates must have a strong background in operational technology (OT), instrumentation, and experience working in high and low voltage substations.

Responsibilities KEY RESPONSIBILITIES

• Design and develop High-Level Design (HLD) and Low-Level Design (LLD) documents for OT cybersecurity infrastructure.
• Perform OT Cybersecurity Gap assessment , risk assessments as per IEC 62443 , NIST and international standards .
• Perform cable routing and physical installation of network and security devices in substations and control centers.

Engineering Design (HLD/LLD) & Drawing Development

• Review and validate Single Line Diagrams (SLDs), existing as-built drawings, and brownfield constraints; raise RFIs and propose constructible solutions.
• Validate panel drawings (GA, internal layout, wiring, interconnection, termination schedules, BOM) and ensure “as-built” updates post commissioning.
• OT Cybersecurity Infrastructure Deployment & Integration
• Implement and integrate OT cyber infrastructure components (e.g., industrial firewalls, switches, IDS sensors, secure remote access, logging collectors) according to approved LLD and standards.
• Support network cutovers, IP schemes, VLAN/VRF mapping, routing design inputs, and secure connectivity between substations and central platforms.
• Ensure installations meet required security baselines and customer utility practices (documentation, labeling, ports, hardening inputs).

Testing, FAT/SAT, Commissioning & Acceptance

• Support/lead FAT preparation and execution: test procedures, inspection checklists, configuration verification, and evidence packs.
• Execute SAT / site commissioning, including pre-checks, power-up, connectivity validation, link testing, redundancy checks, punch lists/snags, and final handover.
• Coordinate with OEMs and customer operations for outage windows, access approvals, and acceptance criteria signoffs.

Qualifications (Technical & Non-Technical) Technical Skills / Core Competencies

• Demonstrated on-site execution in brownfield substations / utility environments (HV/LV interfaces awareness, safe work in operational sites).
• Strong capability in panel/cabinet build supervision, cabling, termination practices, labeling, testing, and as-built documentation.
• Proven ability to prepare HLD/LLD, implementable drawings, and engineering documentation packs.
• Understanding of OT network architecture principles (segmentation, zones/conducts), and integration constraints in utilities.
• Experience supporting FAT/SAT and commissioning activities with structured evidence and acceptance documentation.
• HSE / Compliance (Mandatory or Highly Preferred)
• Strong working knowledge of PTW systems, method statements and risk assessments for live utility sites
• Familiarity with UAE utility HSE expectations including OSHAD-aligned requirements and client safety governance.

Minimum Work Experience

• 7–12 years in cyber infrastructure / OT infrastructure / electrical-telecom execution in utilities, substations, rail, or industrial environments.
• Proven track record delivering brownfield site implementation including cabling/panels and commissioning support.
• Experience in data center infrastructure (rack/cabling/network build) supporting cyber platforms is a strong advantage.

Education

• Bachelor’s degree in electrical engineering / Electronics / Instrumentation / Telecom / Computer Engineering (or equivalent relevant discipline)..
• Relevant OT cybersecurity certifications (at least one):

• ISA 62443 , GICSP ,CISSP
