• Create, review and execute MOPs, test plans, upgrade procedures, configuration checks and technical notes for customer deployments, swaps, maintenance windows and service migrations.
• 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.

• 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.

• Customer faults are resolved or escalated with clear evidence, ownership and urgency.
• Microwave, IP/Ethernet, QoS and synchronization issues are diagnosed in a structured and repeatable way.
• Customer upgrades, migrations and maintenance activities supported by technically sound checks and procedures.
• Recurring issues are converted into knowledge, process improvements or training material for the wider TAC team.
