Pre-check hardware, software, configuration files and scripts before installation, upgrade or customer execution, ensuring that changes are technically valid and operationally safe. Validate new scenarios and customer requirements in the lab or live network, including multiband operation, N+0/N+1 resilience, synchronization plans, QoS/HQoS profiles and service migration from TDM/SDH to Ethernet/IP. Support customer demonstrations, trials, acceptance testing, fault review meetings and post-resolution follow-up to ensure customer satisfaction and service continuity. Participate in the TAC on-call rota and support business-critical escalations when required. Train on new technologies, products and acquired platforms, including microwave and packet networking. Contribute to knowledge base articles, troubleshooting guides and support process improvements based on recurring customer cases and field issues. Work with field teams, product specialists and customers to restore service, validate configurations, support upgrades and improve support processes. Perform other related duties as assigned. Qualifications & Competencies: Proven technical support, transmission operations or field engineering experience in microwave backhaul or carrier transport networks. Strong microwave transmission knowledge, including microwave, E-band and multiband links, RF troubleshooting, link commissioning, traffic migration and service-impact analysis. Strong understanding of Ethernet transport, including VLANs, QinQ, bridge domains, customer/provider bridging, MSTP/RSTP, ERP or equivalent protection mechanisms. Good IP networking knowledge, including IP addressing, subnetting, routing principles, management connectivity, reachability troubleshooting and interpretation of routing/switching diagrams. Practical experience with QoS and HQoS concepts such as classification, marking, queues, schedulers, shaping, policing, prioritisation and traffic verification. Experience with network management platforms and protocols such as NMS/EMS, SNMP, RADIUS, alarms, software management, configuration backups and performance monitoring. Knowledge of synchronization technologies such as SyncE, IEEE 1588 PTP, NTP, SDH/TDM timing and migration from legacy timing designs to packet-based synchronization. Experience with legacy and packet transport services, including PDH, SDH, TDM, Ethernet over microwave, Ethernet over SDH, and migration from TDM/SDH to packet backhaul. Ability to analyse logs, scripts, configuration files, topology diagrams, test results and customer evidence to reach a clear technical conclusion. Good working knowledge of Windows and Linux environments, with basic scripting or automation skills desirable. Professional customer communication skills, including the ability to explain complex technical faults clearly, manage expectations and document actions accurately. Ability to write MOPs, procedures, technical notes and case summaries to a standard suitable for customer and internal use. ITIL awareness or certification is desirable. Cisco CCNA, Cisco ICND, JNCIA, equivalent IP/Ethernet training or demonstrable practical experience is desirable. Experience with MPLS, LDP, RSVP-TE, VPWS, VPLS, L2VPN, L3VPN or similar carrier packet technologies is desirable. Experience with RF and Ethernet/IP test equipment is desirable. Experience with multi-vendor microwave and transport platforms. Fluent business English required; additional languages are advantageous.
