Logical Design Engineer New Bristol

Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale. We are looking for a highly motivated and experienced RTL Design Engineer to join our dynamic team. In this role, you will play a key part in the design and implementation of digital systems, contributing to every stage of the project lifecycle.

Your work will involve developing and optimising Register Transfer Level (RTL) designs for high-performance and power-efficient systems.

• RTL Development and Implementation: Develop and maintain RTL specifications for digital designs, ensuring clarity and accuracy. Implement complex design modules with a focus on performance, power, and area efficiency. Take ownership of design tasks, including planning, execution, and delivery of work packages. Define design tasks for the project, including partitioning, interface specifications, and module definitions. Collaborate with verification engineers to ensure functional correctness through simulation and formal verification.
• Cross‑Functional Collaboration: Work closely with physical design engineers and verification teams to ensure seamless integration of the design.
• Documentation and Standards Compliance: Document RTL design methodologies, module interfaces, and functional requirements. Ensure adherence to coding standards, best practices, and maintainability guidelines.

Qualifications and Skills:

• Education: Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, Computer Engineering, or a related field.
• Experience: 6+ years of experience in digital design, RTL development, or related roles. Familiarity with advanced digital design concepts, such as pipelining, clock‑domain crossing, and power gating. Experience with high‑speed or low‑power design methodologies.
• Soft Skills: Strong analytical and problem‑solving skills. Effective communication and collaboration abilities in cross‑functional teams. A detail‑oriented approach with a focus on quality and efficiency.

How we work:

• Ownership and execution: you will have full agency to drive your work forward.
• Rapid iteration: we all work directly with top leadership to move from idea to hardware on ambitious timelines.
• Full‑stack engagement: hardware, software, silicon, and modelling teams all work closely together to create a product with generational impact.
• Optimistic and pragmatic: we possess the will to win, and to do the hard work to get us there.
• Team player mentality: the mission is bigger than any of us, and we have the curiosity and technical focus to see the best idea shipped, no matter who’s it is.

About us:

• Founded in 2022, team of 70+ which is expanding rapidly.
• Modern, open offices in London and Bristol.
• Collaborative, problem‑solving culture built on deep curiosity, entrepreneurial initiative and technical fluency.
