The SpaceMobile Network Our BlueBird satellites provide full broadband directly to standard smartphones without specialized hardware or phone modifications. Make video calls, browse the web, and use your apps at 4G and 5G speeds from anywhere on Earth.
About the role
We are seeking a talented and motivated Service Engineer to join the Service Enablement team, owning the RF and system-level correctness of every satellite service pass — from beamforming configuration through link budget validation to post-pass RF/RAN analysis.
What they're looking for
- 5+ years of experience in RF engineering, RAN, satellite communications, or wireless systems validation environments
- Practical understanding of link budget analysis for wireless links, free space path loss, elevation-angle-dependent scan loss, EIRP, G/T, interference mitigation, and RF measurement techniques
- Experience with IQ domain/DSP signal analysis, including spectrogram or FFT-based inspection, power-vs-time analysis, and identifying harmonic or co-channel interference
- Deep knowledge of LTE/RAN technologies
- Scripting/automation experience (Python, Lua, MATLAB) for configuration validation, telemetry parsing, and building custom analysis tools
- Proven ability to analyze test results, identify root causes, implement corrective actions, and drive issue resolution across multiple engineering teams
More about this role
AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected.
We are seeking a talented and motivated Service Engineer to join the Service Enablement team, owning the RF and system-level correctness of every satellite service pass — from beamforming configuration through link budget validation to post-pass RF/RAN analysis. This role sits at the intersection of RF systems engineering, satellite payload configuration, and ground segment operations, responsible for configuring, validating, and troubleshooting satellite RF configuration against link budget and RF chain requirements, and for tracing anomalies back through telemetry, IQ captures, and LTE/RAN counters to root cause. This person works across ground station sites applying consistent, version-controlled configuration practices,...
