Senior Logical Design Engineer About Fractile Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the time taken to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to efficiently generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts. The workloads that push to the limits of the current frontier are already transformational; it is the technical and economic limits on inference speed that are constraining progress. The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems.   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. Proven expertise in developing RTL designs for high-performance systems. 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 thereTeam 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 What We Offer Competitive salary: A competitive salary reflective of your experience and the specialist nature of the role.
