Logical Design Engineer

Logical Design Engineer

Fractile is building the silicon, systems and software to break through the memory wall, the fundamental hardware constraint standing between today's AI and what comes next.

The frontier of AI is no longer a research problem. The tasks AI can complete are doubling in complexity every six to seven months and the tokens required to complete them are scaling with it. Sequential reasoning, the kind that can't be parallelised away, means the internal clock speed of inference systems is the critical constraint. What stands between where we are today and the future potential of AI isn't smarter algorithms; it's the hardware to run them fast enough to matter.

Today's chips are hitting their wall. We're building the ones that don't.

Fractile is seeking to increase the clock speed of global progress, one chip at a time.

Our ideal candidate should have 2-4 years’ experience. This is a unique opportunity to accelerate your development, working with an experienced and collaborative team and gaining exposure to a broad range of disciplines. At Fractile, we value ideas from everyone, regardless of title or tenure, and we believe the best engineering happens when people share, question, and learn together. You’ll be joining a culture where your curiosity is encouraged, your input matters, and there’s real room to grow.

We are looking for a highly motivated 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.

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:

• Experience in digital design, RTL development, or related projects.
• Familiarity with advanced digital design concepts, such as pipelining, clock-domain crossing, and power gating.
• Knowledge of 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

  About us:

  • Founded 2022, we're 100+ people across London and Bristol, in the heart of the UK's frontier AI ecosystem, and growing fast.

  • We offer competitive salaries, meaningful equity, and standard company benefits.

  • We believe the hardest problems get solved by the broadest range of minds. We actively encourage applications from underrepresented groups in hardware and software engineering.

  • Hybrid working; 2-3 days in our London and Bristol offices.

  Export controls:

  Our work involves technologies subject to UK and international export control regulations. Certain roles may require additional eligibility checks to ensure compliance with applicable law. We'll be transparent about this throughout the hiring process.
