LEO Satellite 5G NTN Network Integration Engineer

Amazon Inc.; Redmond; Presencial; AUD 196.000 - 265.000; Jornada completa

Descripción de la vacante

Amazon Kuiper Manufacturing Enterprises LLC is seeking an experienced Payload Integration and Test engineer to own the end-to-end network integration across Open RAN, 5G Core, IMS, and satellite payload test systems. The role requires hands-on debugging across CU, DU, RU, gNodeB, Core, and transport in a lab environment.

You will validate 3GPP NTN release 17 behaviors, test VoNR/IMS call flows, and troubleshoot complex NGC/NGAP/GTP/U issues using Wireshark, Linux tools, and protocol traces.

Formación

• Associate's degree or above.
• 5+ years experience integrating, testing, or operating LTE or 5G networks in lab, carrier, vendor, or large scale production environments.
• Strong practical knowledge of 3GPP network architecture, including RAN to Core interfaces and 5G user plane and control plane flows.
• Experience with Open RAN or disaggregated RAN architecture, including CU, DU, RU, gNodeB integration, and related interfaces.
• Knowledge of 3GPP Release 17 NTN concepts and ability to apply standards knowledge during integration and troubleshooting.
• Experience with VoNR and IMS protocols, including SIP, RTP, registration, call setup, media path validation, and failure analysis.
• Strong Linux networking skills and ability to troubleshoot routing, interfaces, packet captures, firewalls, tunnels, timing, and performance.
• Experience with Wireshark or equivalent tools for packet and protocol analysis.
• Experience working in hands on lab environments with physical infrastructure, HIL setups, network equipment, and multi team debug.

Responsabilidades

• Own the network integration path between Open RAN, 5G Core, IMS, transport, lab infrastructure, and satellite payload test systems.
• Debug across CU, DU, RU, gNodeB, Core, routing, switching, tunnels, packet captures, and lab hardware.
• Validate 3GPP Release 17 NTN behaviors from a network integration perspective, including attach, registration, bearer setup, user plane, mobility, and service continuity.
• Integrate and test Open RAN architecture components including CU, DU, RU, F1, E1, Xn, and gNodeB connectivity into lab and payload environments.
• Validate VoNR and IMS call flows, including registration, SIP signaling, media path, QoS, emergency call behavior where applicable, and failure recovery.
• Troubleshoot NGC, NGU, NGAP, GTP U, SCTP, PFCP, VLANs, routing, MPLS, Segment Routing, QoS, MTU, timing, and user plane performance issues.
• Build and execute integration, regression, interoperability, failover, resiliency, and performance test plans for lab and HIL environments.
• Use packet captures, protocol logs, Linux tools, telemetry, and system traces to drive root cause across RF, RAN, Core, payload, transport, and cloud teams.
• Partner with RF, modem, payload, Core, RAN, software, and systems teams to define pass fail criteria and drive issues from ambiguous system behavior to clear resolver ownership.
• Support readiness reviews, test reports, and operational handoff for production bound satellite terrestrial network capabilities.
