Associate RF System Integration Engineer

AST SpaceMobile · Midland, Texas, United States · Sep 25, 2026

AST SpaceMobile and our global partners are building the first and only space-based cellular broadband network to be accessible by standard smartphones. Called SpaceMobile, this ultra-powerful network is being designed to provide connectivity at 4G/5G speeds everywhere on the planet – on land, at sea and in flight. Position Overview We are seeking a highly hands-on Associate 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.

• Practical RF experience across common TT&C frequency bands.

• Demonstrated hands-on experience with:

• RF assemblies and coax harness fabrication

• Antennas and RF subsystems
