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 a SoC/ASIC Architect.
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 drive the architectural definition of complex System‑on‑Chips (SoCs) critical to AST’s satellite communications platforms. You will translate system and product requirements into high‑quality architectural specifications, guiding technical decisions from concept through implementation. Working closely with cross‑functional internal teams and external partners, you will help ensure timely delivery of robust, high‑performance silicon solutions.
Key Responsibilities:
• Work cross‑functionally with hardware, software, verification, product, and systems teams to define and deliver SoC architectures.
• Own and author high‑quality architecture and specification documentation.
• Guide design trade‑offs across performance, power, area, security, and schedule.
• Engage in design, verification, and implementation reviews to ensure architectural integrity.
• Support silicon bring‑up and debug through close collaboration with validation and software teams.
Qualifications
Education:
BEng in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
Experience:
• Demonstrated capability delivering high‑quality architectural specifications.
• Strong background in hardware and digital design.
• Experience working on complex SoCs or ASICs from inception to tapeout.
• Background in some or all of the following areas: Silicon security, Boot flow, CPU architecture, Memory subsystems, Interconnects / NoC, High‑speed interfaces, Peripheral subsystems.
• Competency in Python scripting or programming.
Preferred Qualifications:
• Master’s or PhD degree in a relevant technical discipline.
• Solid understanding of digital signal processing.
• Experience with MATLAB is a plus.
• Prior experience working on RF, communications or signal‑processing ASICs.
Soft Skills:
• Ability to work collaboratively across hardware, software, verification, product, systems, validation, and software teams.
• Ability to work closely with internal teams and external partners.
Technology Stack:
• 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.
