- Practical understanding of link budget analysis for wireless links, free space path loss, elevation-angle-dependent scan loss, EIRP, G/T, interference mitigation, and RF measurement techniques
- Experience with IQ domain/DSP signal analysis, including spectrogram or FFT-based inspection, power-vs-time analysis, and identifying harmonic or co-channel interference
- Deep knowledge of LTE/RAN technologies
- Scripting/automation experience (Python, Lua, MATLAB) for configuration validation, telemetry parsing, and building custom analysis tools
- Proven ability to analyze test results, identify root causes, implement corrective actions, and drive issue resolution across multiple engineering teams
