Job description

Amazon Leo is an initiative to increase global broadband access through a constellation of satellites in Low Earth Orbit. Its mission is to provide fast, reliable, and affordable connectivity to unserved and underserved communities around the world.

The Satellite Systems Integration and Test team validates the complete communications path across the satellite payload, ground gateways, customer terminals, transport networks, and cloud services. We integrate new capabilities, evaluate end-to-end performance, troubleshoot complex failures, and reproduce issues observed during satellite operations.

Key job responsibilities

• Lead end-to-end integration and validation of satellite communications features across the satellite payload, ground gateways, customer terminals, transport networks, and cloud services.
• Develop and execute test campaigns covering functionality, performance, reliability, scale, and failure recovery.
• Translate system and product requirements into test plans, use cases, success criteria, and verification matrices.
• Bring up new test configurations by integrating customer terminals, gateway equipment, satellite payload systems, RF equipment, network infrastructure, and cloud services.
• Troubleshoot complex system issues using packet captures, system logs, telemetry, performance counters, RF measurements, and test data.
• Use tools such as tcpdump, Wireshark, iperf, and Linux networking utilities to isolate packet loss, latency, session failures, and throughput degradation.
• Analyze behavior across the communications stack, including RF link conditions, MAC behavior, Layer 2 and Layer 3 networking, transport protocols, and application performance.
• Troubleshoot packet loss and performance degradation caused by retransmissions, congestion, MTU issues, routing behavior, link conditions, and TCP or UDP behavior.
• Correlate RF conditions such as signal level, interference, link margin, channel impairments, and modulation performance with network and application behavior.
• Reproduce functional and performance issues observed during satellite operations in a controlled lab environment.
• Work with RF and test-equipment vendors to expand lab capabilities using spectrum analyzers, channel emulators, vector signal generators and analyzers, and customer-terminal simulators.
• Automate test execution, data collection, log processing, performance analysis, and reporting using Python or similar languages.
• Communicate technical findings clearly and drive cross-functional teams toward root cause, corrective action, and verification.
• Create and maintain test procedures, verification matrices, test records, dashboards, troubleshooting guides, and program-level status reports.
• Mentor engineers and establish repeatable integration, troubleshooting, and validation practices across the team.
• Experience leading technical investigations across multiple engineering teams and communicating com
