ASIC Design Engineer

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.

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.

• 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.

Education: BEng in Electrical Engineering, Computer Engineering, Computer Science, or a related discipline.

Experience: Deep knowledge of hardware and digital design fundamentals. Strong SystemVerilog knowledge. Experience with SoC integration. Prior experience on complex RTL designs such as high‑speed I/O, CPUs, accelerators, or complex network‑on‑chip implementations. Ability to write clear, high‑quality micro‑architecture specifications. Competency in Python scripting or programming.

• Master’s or PhD degree in a relevant technical discipline.
• Experience on large SoC / ASIC designs.
• RF knowledge is a strong plus.
• Understanding of digital signal processing.
• Experience with MATLAB is a plus.
• Background in communications or mobile silicon system design.

• Ability to collaborate closely with architecture, verification, software, and system teams.
• Ability to work effectively with internal and external stakeholders.
• Ability to provide technical input during design reviews.

• SystemVerilog
• Python scripting or programming
• MATLAB

Physical Requirements: Ability to work in a standard office environment and use a computer for extended periods. Occasional travel may be required to visit suppliers or other AST SpaceMobile design centers.
