FACT
We are seeking a senior-level Wireless Network Optimization Engineer to spearhead end-to-end multi-technology optimization for our 4G LTE and 5G NR networks. 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.
- ZTE RAN Optimization: Analyze and optimize 4G/5G radio network performance using the ZTE product suite to improve overall network quality and customer experience.
- KPI Management & Troubleshooting: Monitor and analyze network KPIs, identify performance degradation, bottlenecks, and interference, and implement corrective optimization actions.
- 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.
- Parameter & Feature Tuning: Perform deep-dive radio network troubleshooting, parameter tuning, and ZTE RAN software feature implementation.
- 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.
- Escalation & Complaints: Investigate high-level customer complaints and provide technical resolutions related to coverage and service quality issues.
- Cross-Functional Collaboration: Collaborate with planning, implementation, transmission, and customer teams to support network modernization and drive continuous network improvement initiatives.
- Reporting & Analytics: Prepare KPI reports, automated dashboards (Power BI/Excel), optimization analysis, and technical presentations for management and stakeholders.
- 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.
- 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.
- 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.
- 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).
- Soft Skills: Strong analytical, problem-solving, communication, and teamwork skills, with the ability to work effectively in a cross-functional and multicultural environment.
