Job summary

Amazon Kuiper Manufacturing Enterprises LLC is hiring a hands-on Network Integration Engineer in Austin, TX to validate end-to-end connectivity across Open RAN, 5G Core, IMS, transport, and satellite test systems. The role focuses on lab-centered integration, debugging, and qualification of space-ground networks with Linux, Python, and packet analysis tools.

The candidate should have at least 5 years of LTE/5G experience, strong 3GPP knowledge, Open RAN exposure, NTN concepts, VoNR/IMS

Qualifications

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.

Responsibilities

Integrate and validate end to end network connectivity across Open RAN, gNodeB, 5G Core, IMS, transport, and LEO satellite test systems.
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.
