Amazon Kuiper Manufacturing Enterprises LLC seeks a hands-on Payload Integration and Test engineer to own 3GPP interpretation, protocol validation, and end-to-end satellite system testing in lab environments.

You will translate standards into executable test cases, analyze protocol logs and traces, and collaborate with architecture, RAN, Core, RF, and operations teams to close interoperability gaps across 3GPP and NTN deployments.

Qualifications

5+ years experience on LTE or 5G protocol validation, systems integration, conformance, interoperability, or protocol stack troubleshooting.
Deep knowledge of 3GPP Release 17, with specific understanding of NTN behavior and satellite related protocol impacts.
Linux proficiency and ability to work directly with test equipment, logs, scripts, and lab systems.

Responsibilities

Lead 3GPP protocol validation for Release 17 NTN features across RAN, Core, IMS, mobility, bearer management, and service continuity.
Define test strategies and pass fail criteria for RRC, NAS, NGAP, XnAP, F1AP, E1AP, PDCP, RLC, MAC, GTP U, IMS, SIP, RTP, and VoNR procedures.
Interpret 3GPP specifications and convert standards requirements into executable integration, regression, conformance, and interoperability test cases.
Validate Open RAN behavior across CU, DU, RU, gNodeB, 5G Core, and IMS systems in lab, HIL, OTA, and end to end environments.
Drive deep debug of protocol failures including registration, attach, PDU session setup, handover, cell reselection, bearer setup, QoS, IMS registration, and VoNR call setup.
