Job summary

Amazon Kuiper Manufacturing Enterprises LLC is seeking an experienced RF systems engineer for hands-on integration, validation, and testing of end-to-end satellite communication systems in lab environments. You will work across space, ground, RF, RAN, Core, and cloud interfaces to qualify production-bound capabilities.

The role emphasizes hardware-in-the-loop, OTA, and channel emulation tests, with a focus on 3GPP NTN behaviors, mobility, Doppler, and service continuity.

Qualifications

• Bachelor's degree in Electrical or Communications Engineering or related field.

Responsibilities

• Integrate RF payload hardware, modems, antennas, Open RAN components, 5G Core, IMS, and lab infrastructure into end to end validation environments.
• Execute RF, OTA, chamber, HIL, modem, and system level tests for NTN and satellite terrestrial network validation.
• Validate 3GPP Release 17 NTN behavior from an RF systems perspective, including synchronization, timing, mobility, Doppler, link quality, beam behavior, and service continuity.
• Correlate RF impairments with protocol and service behavior, including attach, registration, PDU session setup, handover, VoNR, IMS registration, throughput, latency, and packet loss.
• Support Open RAN integration across CU, DU, RU, gNodeB, RF front end, payload hardware, and 5G Core interfaces.
• Use spectrum analyzers, vector signal analyzers, signal generators, channel emulators, RF chambers, OTA setups, and protocol traces to isolate failures.
• Drive root cause on cross domain issues spanning RF hardware, antenna behavior, modem software, RAN configuration, Core behavior, timing, and lab infrastructure.
• Develop integration test procedures, readiness gates, regression coverage, and defect reports for RF plus 3GPP system validation.
• Collaborate with RF, antenna, modem, payload, RAN, Core, network, software, and operations teams to qualify production bound satellite communications capabilities.
