Early Career System Architect
About this role
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.
About the Hardware organisation at Fractile System Architecture sits within the Hardware organisation at Fractile, responsible for designing the chips and systems that power our groundbreaking AI inference accelerator. That’s everything from chip-level architecture and interconnects, through board design and thermal management, to full system integration and bring-up. At Fractile, we know that world-class system architecture is the foundation every other part of the stack is built on.
About the team and role The System Architecture team at Fractile defines how our hardware comes together — from chip interfaces and interconnects through to board design, thermal management, and system-level integration — working closely with digital design, verification, firmware and software teams to make sure architecture choices translate cleanly into working silicon and reliable hardware platforms. As an Early Career System Architect, you’ll support senior architects in defining and refining this architecture, and get hands-on exposure to early prototyping, bring-up, and system testing as ideas become real hardware.
