## Description

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. Fractile is building the next generation of AI computing technology, developing innovative hardware and software solutions designed to transform the performance and efficiency of AI workloads. We're bringing together exceptional talent across semiconductor engineering, software, and AI to solve some of the most ambitious challenges in computing. About the Role We are looking for an experienced and highly technical Chief Information Security Officer (CISO) to lead Fractile's information security, corporate IT, and IT infrastructure functions.

This is a strategic and hands-on leadership role, combining cybersecurity expertise with ownership of IT operations, infrastructure, and service delivery. You will build and lead high-performing teams, establish robust processes and governance, and ensure our technology environment supports Fractile's rapid growth and engineering ambitions. Responsibilities Develop and execute Fractile's information security, IT, and infrastructure strategy, ensuring alignment with business objectives, operational requirements, and global growth. Own and oversee corporate IT operations, infrastructure, networks, cloud environments, endpoints, and enterprise systems, ensuring high availability, performance, security, and scalability. Lead IT service delivery, including employee technology, hardware and software provisioning, IT support, onboarding and offboarding, asset management, and enterprise applications. Protect Fractile's proprietary semiconductor designs, intellectual property, source code, research, and confidential business information against internal and external threats. Partner with engineering teams to ensure secure, reliable, and scalable infrastructure supporting semiconductor development, software engineering, and research environments. Establish and maintain cybersecurity governance, risk management frameworks, policies, and controls aligned with recognised industry standards and regulatory requirements. Lead cybersecurity incident response, threat detection, vulnerability management, disaster recovery, and business continuity planning across IT and infrastructure environments. Oversee IT and security architecture, including identity and access management, network security, endpoint protection, cloud security, access controls, and secure systems integration. Manage technology vendors, infrastructure providers, third-party security risks, IT budgets, procurement, licensing, and supplier relationships to ensure operational efficiency and value.
