Radio Engineer II

Your Role

• Develop concept, tender and detailed designs for Wi-Fi, TETRA, public-safety radio, cellular DAS, LTE/5G, private mobile radio and other project-specific wireless systems.
• Prepare radio and wireless architectures for stations, platforms, tunnels, depots, workshops, stabling areas, control centres, trackside areas and buildings.
• Perform RF propagation modelling, coverage and capacity analysis, interference assessment, frequency/channel planning, link-budget calculations, and design optimisation.
• Determine access-point, antenna, remote-radio-unit and repeater locations based on project requirements, validated survey inputs and applicable design criteria.
• Design passive and active DAS solutions, including antennas, feeders, splitters, couplers, combiners, cable routes and associated equipment.
• Coordinate designs with architecture, civil, MEP, signalling, rolling stock, operations, security, fire and life safety, and IT/network disciplines.
• Prepare design reports, architecture and block diagrams, heat maps, coverage plots, equipment schedules, BOQ/BOM, specifications, interface documents and as-built records.
• Prepare and review survey, FAT, SAT, coverage-acceptance and commissioning procedures;
• Lead assigned design packages and provide technical guidance to CAD/BIM designers for Radio drawings.
• Software and RF Design Expertise

Ekahau

• Create predictive Wi-Fi models using floor plans, wall types, attenuation values, antenna characteristics and project design criteria.
• Perform access-point placement, channel and power planning, capacity modelling and coverage validation for high-density and operationally critical environments.
• Plan and perform passive, active and spectrum surveys; analyse results and prepare professional survey and validation reports.

iBwave

• Develop iBwave models for in-building radio, cellular, public-safety and mission-critical coverage in buildings, stations, tunnels and depots.
• Configure building geometry, construction materials, RF sources, antennas and propagation parameters for reliable predictive modelling.
• Prepare DAS schematics, riser diagrams, equipment layouts, cable schedules, link budgets and coverage-compliance reports, coordinated with CAD/BIM deliverables.

Mandatory Technical Skills

• Expert practical experience with Ekahau for predictive Wi-Fi design, survey planning, survey analysis and reporting.
• Expert practical experience with iBwave for in-building radio, DAS and RF coverage design.
• Strong knowledge of RF propagation, path loss, fading, attenuation, link budgets, antenna characteristics, interference, signal quality and capacity planning.
• Design experience in Wi-Fi and at least two of the following: TETRA, public-safety radio, cellular DAS, LTE/5G, private mobile radio or tunnel radio.
• Experience with indoor and outdoor wireless surveys, RF test methods and coverage acceptance.
• Ability to interpret architectural, civil, MEP, railway and telecom drawings and coordinate within AutoCAD/Revit/BIM environments.
• Knowledge of IP networking, VLANs, QoS, PoE and fibre connectivity supporting wireless systems.
• Knowledge of relevant standards and guidelines, including IEEE 802.11 Wi-Fi standards, ETSI and Ofcom/FCC regulations, EN 50121 EMC requirements, and applicable railway telecommunications standards.
• Experience in radio systems, including leaky feeder, radiating cable, tunnel DAS, distributed antenna systems, and emergency communications coverage.
• Understanding of interfaces with SCADA, signalling, PA/VA, CCTV, passenger information systems, operational telephony, and transmission networks.
• Strong technical writing, design-calculation, stakeholder coordination and multidisciplinary communication skills.

Rail and International Experience

• Demonstrated radio design experience on railway, metro, light rail, station, depot, tunnel or transportation-infrastructure projects.
• Demonstrated wireless design experience for complex or high-occupancy buildings.
• Experience delivering projects across multiple countries or regions and working with geographically distributed teams.
• Ability to apply project requirements, client standards, local regulations and international engineering practices.
