About the job
At AST SpaceMobile, we are pioneering the construction of the world's first global cellular broadband network in space that directly connects with standard mobile devices, leveraging our extensive portfolio of IP and patents tailored for both commercial and governmental applications. Our dedicated team of engineers and space scientists is committed to bridging the connectivity gap for five billion mobile subscribers, aiming to extend broadband access to billions more who are currently unconnected.
Position Overview
We are on the lookout for a proactive RF Assembly, Integration, and Test (AIT) Engineer who will play a pivotal role in the integration, testing, and debugging of flight RF hardware for our fast-paced LEO satellite program at AST SpaceMobile.
This hands-on role focuses on hardware execution. The successful candidate will engage in building, integrating, validating, troubleshooting, and supporting RF systems, ensuring readiness from bench validation through to launch operations. You will closely collaborate with TT&C and GPS design leads responsible for system architecture and requirements, translating designs into robust, flight-ready hardware.
This position emphasizes practical build, test, and repair activities rather than documentation or coordination.
Key Responsibilities
RF Assembly, Integration & Test Execution
- Conduct integration and verification testing for TT&C and GPS flight hardware.
- Take ownership of hands-on integration and testing for:
- Flight radios and transceivers
- Flight antennas
- RF harnessing and coaxial assemblies
- AIT RF racks and ground support equipment (GSE)
- Work directly from released schematics, ICDs, and mechanical interfaces.
- Evaluate RF performance margins, interface integrity, and system compliance through empirical hardware testing and data analysis.
Hands-On Manufacturing & Build Support
- Lead the RF hardware build, inspection, integration, and rework activities.
- Fabricate, inspect, and validate:
- Coaxial cable assemblies
- Connector terminations (SMA, TNC, N-type, etc.)
- Harness routing, clamping, torque application, and strain relief implementation
- Maintain a strong presence on the manufacturing floor during hardware builds.
- Collaborate with manufacturing engineers and technicians to uphold workmanship standards.
- Identify and address integration escapes, workmanship defects, and potential hardware risks.
