SoC/ASIC Architect

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., * 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.

BEng in Electrical Engineering, Computer Engineering, Computer Science, or a related field., * 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., * 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.
