TeleWorld Solutions is seeking a Senior RF Design & Field Testing Engineer to support RF design, prediction modeling, field testing, post-processing, and technical research activities for commercial wireless networks, with a primary focus on 5G NR and FCC Part 15/unlicensed wireless technologies.

This role is responsible for developing RF designs, executing field validation and coexistence testing, analyzing RF performance data, and supporting site integration, deployment, and troubleshooting efforts. The ideal candidate combines deep RF engineering expertise with hands-on experience in RF propagation analysis, spectrum analysis, scanner-based measurements, and industry-standard planning, testing, and post-processing tools to ensure optimal network performance and successful wireless deployments.

Key Responsibilities

• Perform outdoor and indoor RF design using RF prediction and planning tools.
• Conduct RF propagation analysis, coverage prediction, and optimization for wireless networks.
• Utilize RF test equipment including spectrum analyzers, RF scanners, drive-test tools, signal generators, test UEs, and network test devices.
• Plan and execute coexistence testing between 5G NR and other wireless technologies, including FCC Part 15 devices.
• Post-process RF measurement data, including scanner logs, drive-test data, spectrum captures, throughput testing, and geospatial datasets.
• Perform technical research on FCC Part 15 devices, evaluating protocols, RF characteristics, spectrum usage, modulation, duty cycle, channel access methods, and coexistence with 5G.
• Support 5G site integration, deployment, troubleshooting, and field validation activities.
• Develop test plans, test procedures, and technical reports documenting field-testing results.
• Provide RF engineering support for site acquisition and deployment activities.
• Troubleshoot RF, hardware, configuration, and network integration issues.
• Utilize Python for RF data processing, automation, visualization, and test analysis.

Required Qualifications
