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.\nThe 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.\nWe 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\nRTL Development and Implementation:\nDevelop and maintain RTL specifications for digital designs, ensuring clarity and accuracy.\nImplement complex design modules with a focus on performance, power, and area efficiency.\nTake ownership of design tasks, including planning, execution, and delivery of work packages.\nDefine design tasks for the project, including partitioning, interface specifications, and module definitions.\nCollaborate with verification engineers to ensure functional correctness through simulation and formal verification.\nCross-Functional Collaboration:\nWork closely with physical design engineers, and verification teams to ensure seamless integration of the design.\nDocumentation and Standards Compliance:\nDocument RTL design methodologies, module interfaces, and functional requirements.\nEnsure adherence to coding standards, best practices, and maintainability guidelines.\nQualifications and Skills:\nEducation: Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, Computer Engineering, or a related field.\nExperience:\n6+ years of experience in digital design, RTL development, or related roles.\nProven expertise in developing RTL designs for high-performance systems.\nFamiliarity with advanced digital design concepts, such as pipelining, clock-domain crossing, and power gating.\nExperience with high-speed or low-power design methodologies.\nSoft Skills:\nStrong analytical and problem-solving skills.\nEffective communication and collaboration abilities in cross-functional teams.\nA detail-oriented approach with a focus on quality and efficiency.\nHow we work\nOwnership and execution: you will have full agency to drive your work forward\nRapid iteration: we all work directly with top leadership to move from idea to hardware on ambitious timelines\nFull-stack engagement: hardware, software, silicon, and modelling teams all work closely together to create a product with generational impact\nOptimistic and pragmatic: we possess the will to win, and to do the hard work to get us there\nTeam 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\nWhat We Offer\nCompetitive salary: A competitive salary reflective of your experience and the specialist nature of the role.\nEquity & Ownership: meaningful equity so everyone shares in the value creation.\nBenefits: Private Medical, Dental and Vision, Contributory Pension, 25 Days holiday plus bank holidays and Life/Critical Illness Insurance.\nDiverse & fun office: we believe the hardest problems get solved by the broadest range of minds. We are committed to Equal Employment Opportunity through attracting and retaining a diverse team and building an inclusive environment.\nFractile is seeking to increase the clock speed of global progress, one chip at a time. We’ve recently raised $220M from investors including Founders Fund and Accel and our most important work lies ahead.
