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.\nResponsibilities:\n\nKEY RESPONSIBILITIES\nDesign and develop High-Level Design (HLD) and Low-Level Design (LLD) documents for OT cybersecurity infrastructure.\nPerform OT Cybersecurity Gap assessment , risk assessments as per IEC 62443 , NIST and international standards .\nPerform cable routing and physical installation of network and security devices in substations and control centers.\nEngineering Design (HLD/LLD) & Drawing Development\nReview and validate Single Line Diagrams (SLDs), existing as-built drawings, and brownfield constraints; raise RFIs and propose constructible solutions.\nValidate panel drawings (GA, internal layout, wiring, interconnection, termination schedules, BOM) and ensure “as-built” updates post commissioning.\nOT Cybersecurity Infrastructure Deployment & Integration\nImplement and integrate OT cyber infrastructure components (e.g., industrial firewalls, switches, IDS sensors, secure remote access, logging collectors) according to approved LLD and standards.\nSupport network cutovers, IP schemes, VLAN/VRF mapping, routing design inputs, and secure connectivity between substations and central platforms.\nEnsure installations meet required security baselines and customer utility practices (documentation, labeling, ports, hardening inputs).\nTesting, FAT/SAT, Commissioning & Acceptance\nSupport/lead FAT preparation and execution: test procedures, inspection checklists, configuration verification, and evidence packs.\nExecute SAT / site commissioning, including pre-checks, power-up, connectivity validation, link testing, redundancy checks, punch lists/snags, and final handover.\nCoordinate with OEMs and customer operations for outage windows, access approvals, and acceptance criteria signoffs.\n.\nQualifications:\n\n(Technical & Non-Technical)\nTechnical Skills / Core Competencies\nDemonstrated on-site execution in brownfield substations / utility environments (HV/LV interfaces awareness, safe work in operational sites).\nStrong capability in panel/cabinet build supervision, cabling, termination practices, labeling, testing, and as-built documentation.\nProven ability to prepare HLD/LLD, implementable drawings, and engineering documentation packs.\nUnderstanding of OT network architecture principles (segmentation, zones/conducts), and integration constraints in utilities.\nExperience supporting FAT/SAT and commissioning activities with structured evidence and acceptance documentation.\nHSE / Compliance (Mandatory or Highly Preferred)\nStrong working knowledge of PTW systems, method statements and risk assessments for live utility sites\nFamiliarity with UAE utility HSE expectations including OSHAD-aligned requirements and client safety governance.\n\nMinimum Work Experience\n7-12 years in cyber infrastructure / OT infrastructure / electrical-telecom execution in utilities, substations, rail, or industrial environments.\nProven track record delivering brownfield site implementation including cabling/panels and commissioning support.\nExperience in data center infrastructure (rack/cabling/network build) supporting cyber platforms is a strong advantage.\nEducation\nBachelor’s degree in electrical engineering / Electronics / Instrumentation / Telecom / Computer Engineering (or equivalent relevant discipline)..\nRelevant OT cybersecurity certifications (at least one):ISA 62443 , GICSP ,CISSP","description_format":"text","description_chars":3842,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cybersecurity","Information
