You will own the testing strategy and automation framework for NTN, NR, LTE, and IMS protocol stacks, covering Non-Terrestrial Networks, Telephony, and eSIM. You will validate network slicing, unified call logs, and emergency services while debugging issues reported by field test teams.

This role is on-site.

Responsibilities

• Develop and maintain automation frameworks using Python and Shell scripting for NTN, Telephony, and eSIM testing.
• Execute functional, regression, sanity, and feature testing for Skylo, Starlink, and CBRS 5G private networks.
• Validate NR, LTE, and IMS call flows, handovers, and network slicing using Keysight UXM, Anritsu, and CMW call boxes.
• Analyze logs and triage defects using QXDM, QPST, QCAT, and Shannon Tools for Android and network issues.
• Define and implement testing strategies for NTN, Telephony, and eSIM CBRS environments with operator partners.

Required Skills

• 6 to 8+ years of experience in NTN, NR, LTE, and IMS protocol stack development and testing.
