• Good knowledge of 5G NSA and SA
• Verbal and written communication, problem-solving, customer-service, and interpersonal skills
• Ability to work independently and manage your time

Nice to have

• Associate degree or higher in a technical field
• Familiarity or expertise with UE log post-processing tools (QXDM, QCAT, Wireshark, and modem diagnostic monitors) and a good understanding of over-the-air (OTA) signaling messages
• Ability to analyze and debug IMS features, including registration, VoLTE, VoWiFi, ViLTE, conferencing, SMS, MMS, and RCS
• Experience post-processing UE logs and analyzing KPIs
• LTE and 5G NR field-test experience on a live network
• Test experience with 5G SA, NSA, and NTN, including official carrier field test plans (e.g., Verizon DFIT, AT&T AVDFT, T-Mobile F4L)
