T-Mobile is America’s supercharged Un‑carrier, delivering an advanced 4G LTE and transformative nationwide 5G network that will offer reliable connectivity for all. Senior Engineers, Radio Frequency located in Livonia, MI will provide radio frequency (RF) and/or wireless transmission equipment requirement support; responsible for end‑to‑end design, deployment and optimization of next‑generation networks (macro, small cells).

• Perform multi‑band LTE Optimization & Design of LTE 2500, L1900, L2100, and L800 of macros and small‑cell sites.
• Perform small‑cells design for coverage and capacity enhancements and identify new hub locations. Responsible for end‑to‑end RF design and deployment of T‑Mobile 3G, 4G and 5G network.
• Perform coverage parity analysis of different 4G, 5G bands, run predictions, and create delta maps.
• Support monthly POR governance (site prioritization and RFDS).
• Run predictions using performed POPs analysis, performed POR objective analysis and enhance 5G coverage based on analysis.
• Perform OPEX and CAPEX analysis for sites with deployment team and provide conclusions based on coverage, users, costing and morphology.
• Parameter tuning (LTE idle and connected mode parameters) and coverage analysis to improve overall performance of the network.
• Troubleshoot customer issues and propose solutions for improvement; perform multi‑band load balancing to optimize traffic among LTE carriers and multi‑technology load balancing among technology layers.
• Perform drive testing using Xcal and TEMS and analyse Layer‑3 protocols of drive‑test logs for different technologies such as LTE & 5G.
• Monitor performance indicators for CS and PS domain services in terms of accessibility, retainability, call completion success rate, integrity, mobility, system utilization and availability for Ericsson, Samsung and Nokia OEMs.
• Troubleshoot typical problems like interference, hand‑off failure, low throughput/poor SINR.

• Experience (1) Demonstrated ability in RF propagation tools including Planet, Atoll, or comparable tools to design new macro sites, small cells, predict signal quality and interference levels, identify areas of concern and their impact on coverage and performance, and develop corrective recommendations.
• Experience (2) Troubleshoot external and internal interference using a spectrum analyzer. Monitor performance indicators for CS and PS domain services in terms of accessibility, retainability, call completion success rate, integrity, mobility, system utilization and availability for Ericsson and Nokia OEMs.
• Experience (3) Perform monthly POR governance analysis using site prioritization, capacity analysis, RFDS, coverage analysis, drive test, and link budget.
• Experience (4) Perform network optimisation for 3G, 4G & 5G networks and improve KPI’s which include call failure rate, call drop rate, data throughput by analysing Layer‑3 messages of drive logs using Actix or comparable tools.
• Experience (5) Troubleshoot customer issues and propose solutions for improvement; perform multi‑band load balancing to optimise traffic among LTE carriers and multi‑technology load balancing among technology layers.
• Experience (6) Perform multi‑band LTE Optimisation & Design of LTE 2500, 1900, L2100, and L800 of macros and small‑cell sites. Parameter tuning of LTE idle and connected mode parameters.
