Senior Digital Design Engineer

Job Title: Senior Digital Design Engineer

Location: Cambridge, United Kingdom

Job Type: Permanent

Salary: 65K - 88K GBP per annum DOE

Role Overview:

Work at the forefront of open silicon and hardware security, contributing to next-generation secure ASIC/SoC designs based around RISC-V, cryptographic accelerators and hardware security IP.

This is a hands-on opportunity to make a direct impact on advanced silicon architecture and RTL design.

Key Responsibilities:

• Contribute to the architecture and specification of new digital designs and enhancements to existing IP.
• Develop and maintain System Verilog RTL across a range of digital silicon IP.
• Work closely with Design Verification engineers on test plans, coverage and regression debugging.
• Collaborate with security specialists to implement robust hardware security and protection features.
• Support verification closure through both design expertise and hands-on verification contributions.
• Participate in code reviews and collaborative development within an open-source engineering environment.
• Work with engineers across multiple organisations and disciplines to support IP integration into silicon products.
• Take technical ownership of IPs or subsystems where required, ensuring high-quality and timely delivery.
• Provide technical guidance and mentoring to less experienced engineers.

Experience Required:

• Minimum 4+ yrs' industry experience in digital IC/ASIC design
• Master's degree or PhD in Electrical/Electronic Engineering or another relevant technical discipline.
• Strong hands-on System Verilog / RTL experience.
• Good knowledge of industry-standard EDA tools from Synopsys, Cadence and/or Siemens.
• Experience working with Git-based development and code collaboration platforms such as GitHub, GitLab or Gerrit.
• Proven experience contributing to full-chip development cycles, from initial planning and RTL through tape-out, bring-up and post-silicon validation.
• Ability to take ownership of significant areas of design and work with minimal supervision.
• Comfortable contributing beyond RTL where required, including silicon architecture, system integration, verification, chip bring-up and post-silicon testing.
• Strong project ownership skills, including estimating work, communicating progress and delivering to agreed timelines.

Desirable:

• Experience across multiple areas of digital silicon/IP, such as CPU cores, memory subsystems, interconnects, I/O controllers or cryptographic accelerators.
• Understanding of hardware security, including countermeasures against physical attacks such as side-channel analysis and fault injection.
• Experience with RISC-V or similar processor architectures.
• Programming experience in Python, C and/or Rust, particularly for automation, RTL generation, software interfaces, testing or system integration.
