Operating from a strategic tier, this individual will take full ownership of RAN performance across the network, driving advanced parameter configurations and deep-dive protocol trace analysis. The role requires a technical expert capable of leveraging proprietary ZTE optimization platforms to maximize network quality, handle complex operator escalations, and deliver executive-level performance insights.\n\nDuties & Responsibilities\n\n ZTE RAN Optimization: Analyze and optimize 4G/5G radio network performance using the ZTE product suite to improve overall network quality and customer experience.\n\n KPI Management & Troubleshooting: Monitor and analyze network KPIs, identify performance degradation, bottlenecks, and interference, and implement corrective optimization actions.\n\n Protocol & Call Flow Analysis: Apply a strong understanding of call flow, handover flow, mobility management, and wireless communication technologies across CS, VoLTE, and PS RAN to isolate root causes.\n\n Parameter & Feature Tuning: Perform deep-dive radio network troubleshooting, parameter tuning, and ZTE RAN software feature implementation.\n\n Data Analysis & Tooling: Perform post-processing using TEMS, ZTE WNG, and analysis through MR-based tools such as NGI, NetMax, and CEMS to identify coverage, quality, and throughput issues, and provide targeted optimization solutions.\n\n Escalation & Complaints: Investigate high-level customer complaints and provide technical resolutions related to coverage and service quality issues.\n\n Cross-Functional Collaboration: Collaborate with planning, implementation, transmission, and customer teams to support network modernization and drive continuous network improvement initiatives.\n\n Reporting & Analytics: Prepare KPI reports, automated dashboards (Power BI/Excel), optimization analysis, and technical presentations for management and stakeholders.\n\nDesired Experience & Qualification\n\n Education & Experience: Bachelor’s degree or above in Telecommunications, Electronics, Computer Science Engineering, or a related field, with 8+ years of dedicated wireless network optimization experience.\n\n Technical Expertise: Strong expertise in LTE and 5G NR air interface technologies, mobility management, root-cause analysis, and mitigation techniques with a solid understanding of RAN principles.\n\n ZTE Vendor Expertise: Hands-on experience with proprietary ZTE tools, explicitly UME, NGI, NetMax and WNG, along with ZTE-specific parameter sets and feature configurations.\n\n Analytics & Software Tools: Proficiency in data analytics and report generation using Microsoft Excel and Power BI, alongside standard optimization tools (TEMS, Nemo, QGIS, or Google Earth).\n\n Soft Skills: Strong analytical, problem-solving, communication, and teamwork skills, with the ability to work effectively in a cross-functional and multicultural environment.\n\nMandatory Requirements\nMandatory Requirements:\n\n Minimum 6 years of hands-on RF network planning experience, with solid 4G/LTE and 5G NR planning experience.\n\n Strong hands-on experience with Atoll, with the ability to independently perform RF planning, coverage simulation, capacity analysis and planning deliverables.\n\n Ability to independently perform 5G Nominal Planning, including site layout, site selection, coverage target design, layer planning and capacity planning.\n\n Practical experience in Propagation Model Tuning using CW measurement and/or drive test data.\n\n Ability to independently perform 5G Capacity Planning based on subscriber distribution, traffic forecast, PRB utilisation and traffic hotspot analysis.\n\nShould you meet these requirements, send CV to
