Senior Telecom Engineer

Role Overview

Lead the design integration and delivery of telecommunication and ICT systems for High-Speed Rail (HSR) assets including stations depots stabling yards OCC/CC and associated facilities. The role covers fixed and wireless communications transmission networks passenger information public address time synchronization and integration with rail operational systems and critical building systems

Key Responsibilities

• Lead end-to-end design integration and delivery of telecom/ICT systems for HSR assets including stations depots/stabling yards OCC/CC back-of-house buildings and corridor-wide communications.
• Develop Basis of Design (BoD) system architecture and design deliverables (concept to detailed design) for telecom systems including as applicable:
• Transmission/backbone networks (fiber backbone OTN/MPLS/IP/WAN) station LAN OCC networks
• Structured cabling (copper/fiber) containment/pathways telecom rooms (MDF/IDF) racks/ODF patching and labeling philosophy
• Radio communications (TETRA/DMR LTE/5G GSM-R / FRMCS-ready concepts where required) indoor/outdoor coverage planning; tunnel communications concepts such as leaky feeder where in scope
• Telephony / VoIP (SIP/VoIP hotline/emergency phones help points)
• Wi-Fi (public and operational) staff mobility solutions (if required)
• Passenger Information / CIS (PIDS) and Public Address / Voice Alarm (PA/VA) interfaces zoning and priority philosophy
• Master Clock / Time Synchronisation (GPS receivers NTP/PTP distribution) for event correlation and operational systems
• Telecom-side integration considerations for CCTV/Security transport (in coordination with Security Systems)
• Produce and coordinate design outputs: system schematics single line diagrams network block diagrams device layouts telecom room layouts equipment schedules BOM duct/fiber routing plans and interface matrices.
• Perform/coordinate network sizing and capacity engineering: bandwidth QoS latency/jitter considerations (voice) multicast where relevant IP addressing concepts PoE budgets (where applicable) storage/transport assumptions for video and operational applications.
• Define resilience and redundancy philosophy (ring/topology concepts N1 for critical nodes) failover expectations maintainability access spares strategy and O&M handover requirements.
• Manage interfaces with OCC/CC operations and other rail systems: define segregation between corporate IT / operational networks / security networks and document interfaces to SCADA BMS/EMS signaling power maintenance systems AFC (if applicable).
• Coordinate with Architecture (public area coverage rooms/data sheets) MEP (power/UPS loads HVAC requirements earthing/grounding fire interfaces) Civil/Structural (duct banks trenches mounting) and BIM teams to ensure spatial coordination and clash-free design.
• Prepare technical specifications Employers Requirements / performance specs compliance matrices and support technical notes for authority submissions and stakeholder reviews (as applicable).
• Support procurement and vendor management: technical evaluations RFIs design reviews workshops and value engineering while protecting performance and operational requirements.
• Lead and/or review testing commissioning and integration documentation and activities: FAT/SAT network acceptance tests end-to-end service verification (voice radio coverage PIDS/PA functions time sync) and integration test plans.
• Apply project QA/QC and governance: ensure document control compliance traceability of assumptions and effective management of design change impacts on telecom architecture.
