Role OverviewThe operational heartbeat of modern data centres is not mechanical or electrical infrastructure it's the integration of those systems into a single, resilient intelligence layer. At 80+ MW scale and with rack densities approaching 100 kW, ICT and security architecture have become mission-critical engineering disciplines. Ramboll is building its MENA data centre practice from the ground up with 450+ dedicated data centre MEP engineers globally. The Principal ELV & ICT Engineer will be the systems integration authority at the heart of the regional team, working on mission-critical data center projects.Job DescriptionKey ResponsibilitiesThe Principal ELV & IBMS Engineer will act as a systems architect and technical lead responsible for end-to-end ELV system design, IBMS architecture, integration strategy, and commissioning support.This role goes beyond equipment specification and requires complete lifecycle ownership, from system architecture definition and integration strategy through detailed design, vendor evaluation, testing procedures, and live commissioning validation.You will lead cross-discipline conversations on BMS-electrical interfaces (EPMS integration, power monitoring), mechanical coordination (HVAC sensor networks, control logic), security integration (SOC workflows, surveillance architecture), and IT systems (DCIM, network protocols). Therefore, it's required to possess working knowledge of electrical systems (power monitoring, EPMS interfaces), mechanical systems (HVAC controls, sensor networks), fire safety (FAS integration, alarm management), security operations, network architecture, and commissioning procedures. Client Engagement & Technical LeadershipAct as the primary ELV/ICTtechnical contact for clients, leading system architecture discussions, integration strategy, and operational readiness with senior engineering and operations teamsDirectly engage with client-side SMEs, security operations centres (SOC), IT teams, global stakeholders, and multidisciplinary design teamsLead technical discussions on system integration philosophy, resilience architecture, protocol strategy, and operational workflowsOwn preparation of IBMS Design Basis Reports (DBR), system architecture narratives, cause & effect matrices, and integration strategy documentationParticipate in proposals drafting and responses to RFP and TQR System ArchitectureDefine complete ELV/IBMS architecture including BMS/EPMS/DCIM integration, security systems (CCTV/VMS, access control, perimeter protection), fire alarm systems (FAS, VESDA), PA/VA systems, and operational workflowsDesign integrated systems for hyperscale and colocation facilities in the 10100 MW IT load range, with security zoning and network architecture scaled to mission-critical requirementsDevelop multi-layer security architectureDesign HVAC monitoring and control integration with electrical power monitoringEstablish system redundancy philosophy aligned with uptime requirements and Tier III/IV standardsDevelop network topology and sequence of operations for integrated system behavior Engineering Analysis & System IntegrationDesign end-to-end BMS/IBMS solution: PLC architecture, server redundancy, communication protocols (BACnet, Modbus, IEC-61850, OPC UA), and control logicDevelop complete I/O lists, control logic, and cause & effect matrices for all integrated systemsCoordinate electrical integration, EPMS data flows, power monitoring sensors, emergency shutdown sequences, and load shedding logicCoordinate mechanical integration, HVAC sensor networks, chiller/CDU control loops, and thermal management feedback into IBMSDesign security operation centre (SOC) workflows, alarm management strategy, and operator interface logicValidate system protocols and .
