RF System Integration Engineer

AST SpaceMobile · Midland, Texas, United States · Mar 3, 2026

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. Position Overview We are seeking a highly hands-on RF Assembly, Integration, and Test (AIT) Engineer to execute, integrate, test, and debug flight RF hardware supporting a fast-paced LEO satellite program at AST SpaceMobile. This is a hardware-centric execution role. The selected candidate will personally build, integrate, verify, troubleshoot, and support RF systems from bench validation through launch operations. You will partner directly with TT&C and GPS design leads who own system architecture and requirements, translating released designs into robust, flight-ready hardware. This is not a documentation or coordination position — it is a build, test, and fix role.

Responsibilities:

• RF Assembly, Integration & Test Execution

• Execute integration and verification testing for TT&C and GPS flight hardware.

• Own hands-on integration and test of:

• 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.

• Verify RF performance margins, interface integrity, and system compliance through empirical hardware testing and data analysis.

• Hands-On Manufacturing & Build Support

• Personally drive RF hardware build, inspection, integration, and rework activities.

• Fabricate, inspect, and validate:

Requirements:

• Review test data packages, close discrepancy reports, and verify flight readiness.

• Support launch site operations, including last-minute RF troubleshooting and configuration validation.

• What Winning Looks Like

• RF hardware integrates cleanly and predictably in AIT.

• Issues are identified early, debugged efficiently, and closed with permanent corrective action.

• RF systems perform consistently from bench validation → environmental test → launch → orbit.

• You can point to the spacecraft and confidently state: “I built and tested that system.”

• BS or MS in Electrical Engineering, or equivalent demonstrated hands-on RF experience.

• Strong practical RF experience across common TT&C frequency bands.

• Demonstrated hands-on experience with:

• RF assemblies and coax harness fabrication

• Antennas and RF subsystems
