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 an ASIC Design Engineer to contribute to the design and implementation of complex silicon solutions used in AST’s space‑based communications systems.

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, you will focus on high‑quality RTL development, micro‑architecture definition, and close collaboration across engineering disciplines. You will work alongside architecture, verification, and system teams—both internal and external—to deliver robust, high‑performance ASIC and SoC designs from concept through tape‑out.

Key Responsibilities:

• Create high‑quality micro‑architecture specifications and RTL code.

• Contribute to SoC integration and subsystem development.

• Work with internal and external stakeholders, including architecture, verification, and software teams.

• Participate in design reviews, providing technical input.

• Ensure alignment with requirements and design best practices.
