AST SpaceMobile

<div><div><p>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.</p></div><p><b>
Position Overview</b></p>
<p>
The RF Engineer is responsible for RF‑layer service readiness for satellite&ndash;cellular connectivity across our LEO/MEO constellation. This role ensures that beams, links, and terminal RF chains consistently meet the performance, robustness, and reliability required for commercial satellite broadband and direct‑to‑device (NTN) services.</p>
<p>
You will collaborate across RF systems, waveform/PHY, NTN/RAN engineering, field‑test teams, and network engineering to define RF acceptance criteria, shape test campaigns, interpret performance results, and provide RF sign‑off for launches, market activations, and major software or hardware releases.</p>
<p>
This role blends deep RF engineering expertise, practical SATCOM experience, and structured acceptance discipline to transform a complex satellite constellation into predictable, high‑quality, repeatable services.</p>
<p>
Positioned at the center of AST SpaceMobile's RF and service‑readiness stack, the RF Engineer ensures that the constellation, beams, and terminals perform to the standards required for real‑world satellite broadband and NTN deployments. Success requires strong RF fundamentals, hands‑on SATCOM experience, and a disciplined acceptance mindset that combines technical depth with clear, actionable communication to cross‑functional teams.</p>
