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
