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 SoC Validation Engineer .

The Silicon Team in Edinburgh is a small, highly focused group responsible for developing high‑value silicon that is core to AST’s mission of “Connecting the unconnected” —delivering the world’s first space‑based mobile broadband network.

The team works collaboratively to define and build next‑generation silicon, exploring advanced silicon technologies to continuously improve performance, capability, and efficiency. This is a hands‑on environment where silicon decisions directly impact AST’s ability to deliver a global communications network from space.

In this role, the Validation Engineer will be responsible for defining, executing, and reporting on the validation of complex integrated circuit devices, working closely with System Definition, IC Design, and Software teams. This role spans pre‑silicon validation using FPGA prototypes through to post‑silicon bring‑up and system‑level validation, ensuring devices meet performance, functionality, and system integration requirements.

Key Responsibilities:

• Work closely with System Definition and IC Design teams to ensure devices are specified with optimal ball placement and external component selection to meet PCB technology and overall system requirements.

• Define and specify laboratory equipment and infrastructure required to effectively test and validate devices.

• Perform validation bring‑up using FPGA prototypes prior to IC manufacture.

• Define comprehensive validation test plans to validate IC…
