Hands-on 5G NTN Network Integration & Test Engineer

Amazon Inc.; Austin (TX); Vor Ort; USD 136.000 - 184.000; Vollzeit

Zusammenfassung

Amazon Leo is building a Low Earth Orbit satellite constellation to deliver high-speed, low-latency connectivity worldwide. This role focuses on hands-on integration, validation, troubleshooting, and qualification of end-to-end satellite communications across space, ground, RF, RAN, Core, and cloud infrastructure in a lab-centered environment.

The engineer will debug complex systems using Linux, Python, protocol traces, and packet captures, and will partner with multi-team groups to define

Qualifikationen

• Associate's degree or higher.
• 5+ years experience integrating, testing or operating LTE or 5G networks in lab, carrier, vendor, or large-scale production environments.
• Strong knowledge of 3GPP architecture including RAN to Core interfaces and 5G user plane/control plane.
• Experience with Open RAN or disaggregated RAN architectures including CU/DU/RU and gNodeB integration.
• Knowledge of 3GPP Release 17 NTN concepts and integration troubleshooting.
• Experience with VoNR and IMS protocols (SIP/RTP) and call setup.
• Strong Linux networking skills and ability to troubleshoot routing, interfaces, packet captures, firewalls, timing, and performance.
• Experience with Wireshark or equivalent tools.

Aufgaben

• Own the network integration path between Open RAN, 5G Core, IMS, transport, lab infrastructure, and satellite payload test systems.
• Integrate and validate end-to-end network connectivity across Open RAN, gNodeB, 5G Core, IMS, transport, and satellite test systems.
• Validate 3GPP Release 17 NTN behaviors including attach, registration, bearer setup, user plane and mobility.
• Integrate and test Open RAN components (CU/DU/RU/F1/E1) into lab and payload environments.
• Validate VoNR and IMS call flows including SIP signaling and QoS.
• Troubleshoot NGC/NGU/NGAP, GTP U, SCTP, PFCP, VLANs, routing, MPLS, XR, timing and user plane performance issues.
• Develop and execute integration, regression, interoperability, failover, resiliency, and performance test plans for lab/HIL environments.
• Use protocol logs, Linux tools, telemetry and traces to drive root cause across RF, RAN, Core, payload, transport and cloud teams.
• Collaborate with RF, modem, payload, Core, RAN, software and systems teams to define pass/fail criteria and drive issue resolution.
• Support readiness reviews, test reports and handoff for production-bound satellite terrestrial networks.
