Job Description

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 RAN System Engineer to participate in definition, integration, optimization, and product roadmap execution of LTE/5G radio systems across our global satellite-ground infrastructure—the first and only space-based cellular broadband network accessible directly by standard mobile phones.

This role sits at the intersection of beamforming, fronthaul design, scheduler behavior, and interference management, while also owning the translation of system capabilities into a coherent product roadmap and serving as a trusted technical interface to customers and partners.





The ideal candidate brings deep experience from a leading RAN vendor, a robust understanding of baseband design and scheduling pipelines, and the ability to bridge engineering realities with customer expectations in a rapid-moving, non-traditional deployment environment.

Key Responsibilities
Ensure robust operation of terrestrial RAN features—such as scheduling, MIMO, mobility, and interference coordination—when deployed over AST's space-based infrastructure via standard CPRI/eCPRI interfaces.
Own cell- and network-level performance modeling, including:
Spectral efficiency
Cell density and reuse strategies
Beam transitions and UE tracking
Interference prediction and mitigation
Scaled ground GW operation
Drive feature provisioning end-to-end—from requirements definition and vendor engagement through integration, validation, and controlled enablement across the network—ensuring recent capabi
