We are seeking a Mobile Field Test Engineer to support 5G/LTE and NTN (Non-Terrestrial
Network) / Satellite testing in real-world environments. This role focuses on end-to-end
validation, log analysis, and troubleshooting across terrestrial and satellite (LEO/GEO, Direct-to-Device) networks in collaboration with R&D, QA, and carrier teams.

  • Perform field/drive testing for 5G NR, LTE, 3G, and NTN/satellite networks
    Execute RF, mobility, and data performance testing (throughput, latency, call scenarios)
  • Validate handover between cellular and satellite (NTN) networks
    Capture and analyze logs using QXDM, QPST, XCAL/XCAP, Shannon DM
  • Troubleshoot VoLTE/VoNR, data connectivity, and network performance issues
  • Develop and execute test plans (routes, devices, KPIs, network conditions)
  • Perform packet analysis using Wireshark (TCP/IP, UDP)
  • Validate software/modem updates and feature enhancements
  • Document results and deliver clear technical reports
  • Configure and maintain test devices, SIM/eSIM, and test environments
  • Collaborate with carrier labs, OEMs, and chipset teams for issue resolution

Required Qualifications

  • Bachelor’s degree in Telecommunications, Electrical Engineering, Computer Science, or equivalent experience
  • Hands-on experience in mobile field testing / wireless / telecom testing
  • Strong knowledge of 5G NR, LTE, WCDMA/UMTS, GSM
  • Working knowledge of NTN / satellite communications (LEO/GEO, latency, coverage)
  • Experience with log analysis tools (QXDM, QPST, XCAL, Shannon DM or similar)
  • Understanding of network protocols (TCP/IP, UDP, OSI model)
  • Experience with Android device testing and mobile software validation
  • Familiarity with VoLTE/VoNR, data testing, and KPI validation
  • Proficiency in Microsoft Office for reporting
  • Strong analytical and troubleshooting skills

Preferred Qualifications

  • Experience with 3GPP Release 17+ NTN standards
  • Hands-on exposure to Direct-to-Device (D2D) satellite connectivity
  • Understanding of 5G protocol stack (PHY, MAC, RRC, NAS signaling)
  • Experience in carrier certification or satellite communication testing
  • Knowledge of GNSS/GPS, RF propagation, and mobility scenarios
  • Familiarity with automation/scripting (ADB, Python, Shell)
  • Experience with Wi-Fi, Bluetooth coexistence testing

Work Environment

  • Combination of field testing (drive/walk testing) and lab validation
  • Testing may include outdoor, remote, or limited-connectivity environments
  • Requires travel (up to 15%) based on project scope
  • May require extended hours or weekend work for test cycles and deployments
  • Hands-on work with mobile devices, RF equipment, and satellite-enabled hardware

Requirements

  • Valid driver’s license and ability to travel to test locations
  • Ability to work in field environments and handle test equipment
