Associate RF System Integration Engineer

From the posting

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.

Key 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. …
