Fractile is looking for a Hardware System Test Engineer to help build the test infrastructure that supports its next-generation AI hardware systems. The company was founded in 2022 around the idea that the speed of AI inference is a major bottleneck to progress, and that unlocking the full value of frontier models requires rethinking the hardware they run on. Its work focuses on chips and systems designed to generate outputs at very high speed while handling the demands of long-context, large-model inference.<\/p>\n

This role is based in Bristol and sits within a team working across hardware, software, silicon, and modelling to bring ambitious products from concept to reality. The company describes its culture as one of ownership, rapid iteration, full-stack collaboration, pragmatic optimism, and a strong team-first mindset.<\/p>\n

What you will do<\/h3>\n
    \n
  • Develop and maintain system-level tests that can detect hardware defects across individual servers and rack-scale systems.<\/li>\n
  • Build checks that identify assembly problems, marginal or failing components, physical damage, cabling faults, interconnect issues, and cooling-related defects.<\/li>\n
  • Create diagnostic tests for service and field use, including tools for RMA triage, repair verification, and preventive maintenance.<\/li>\n
  • Design tests that run quickly and deterministically, with clear pass\/fail logic and failure output that manufacturing and service technicians can use immediately.<\/li>\n
  • Develop PCIe defect-detection coverage for issues such as lane faults, degraded links, polarity errors, retimer failures, and intermittent connectivity problems.<\/li>\n
  • Implement stress and soak testing to surface latent or borderline hardware issues that may not appear in short functional checks.<\/li>\n
  • Troubleshoot failed tests and hardware problems, carry out root-cause analysis, and escalate design or process concerns when appropriate.<\/li>\n
  • Review failure information from factory and field environments to identify gaps in coverage and suggest improvements to the test strategy.<\/li>\n
  • Support the rollout, version control, and ongoing upkeep of test software across factory and service operations.<\/li>\n
  • Partner with software teams to integrate test functionality into production system software.<\/li>\n
  • Work closely with hardware, manufacturing, service, and reliability teams to ensure the tests match known failure modes and real operational needs.<\/li>\n<\/ul>\n

    What the company is looking for<\/h3>\n
      \n
    • Between 3 and 7 years of experience in system, server, or hardware test engineering, ideally gained in manufacturing or service settings.<\/li>\n
    • A strong grasp of server architecture, PCIe fabrics, power delivery, cooling systems, and the common ways hardware fails.<\/li>\n
    • Hands-on experience building or running hardware defect-detection or diagnostic tests.<\/li>\n
    • Experience working in Linux-based test environments.<\/li>\n
    • Familiarity with BMC-managed systems, including basic use of OpenBMC or Redfish interfaces.<\/li>\n
    • Strong debugging ability, including the judgment to separate a broken test from a genuine hardware fault.<\/li>\n
    • The ability to produce clear test code, logs, and documentation that can be used operationally.<\/li>\n<\/ul>\n

      Preferred background<\/h3>\n
        \n
      • Experience with AI accelerator systems, GPUs, or high-performance compute servers.<\/li>\n
      • Exposure to PCIe Gen4, Gen5, or Gen6 platforms, or other high-speed serial interconnect technologies.<\/li>\n
      • Experience diagnosing intermittent, marginal, or temperature-dependent hardware failures.<\/li>\n
      • Experience with liquid-cooled servers or other platforms with challenging thermal characteristics.<\/li>\n<\/ul>\n

        How the team works<\/h3>\n
          \n
        • People are expected to take ownership and move work forward with a high degree of autonomy.<\/li>\n
        • The team iterates quickly and works directly with senior leadership to turn ideas into hardware on aggressive timelines.<\/li>\n
        • Engineers collaborate across hardware, software, silicon, and modelling disciplines to build products with long-term impact.<\/li>\n
        • The culture values determination, practicality, and the willingness to do difficult work to achieve ambitious goals.<\/li>\n
        • Team members are expected to focus on the best technical solution, regardless of where the idea originated.<\/li>\n<\/ul>\n

          What is offered<\/h3>\n
            \n
          • A competitive salary aligned with experience and the specialist nature of the role.<\/li>\n
          • Meaningful equity so employees share in the value created by the business.<\/li>\n
          • Private medical, dental, and vision insurance.<\/li>\n
          • A contributory pension plan.<\/li>\n
          • 25 days of annual leave plus bank holidays.<\/li>\n
          • Life insurance and critical illness cover.<\/li>\n
          • A diverse and enjoyable office environment.<\/li>\n
          • A commitment to equal employment opportunity, inclusion, and building a broad team with varied perspectives.<\/li>\n<\/ul>\n

            Additional company information<\/h3>\n

            Fractile says it has recently raised $220 million from investors including Founders Fund and Accel, and that its most important work is still ahead. The company also notes that its work involves technologies subject to UK, US, and other international export-control regulations, so some roles may require extra eligibility checks to ensure legal compliance. It says it will be transparent about this during the hiring process.<\/p>\n

            How to apply<\/h3>\n

            Applications are submitted through the online job application form. The form asks for standard details such as name, email, phone number, resume or CV, cover letter, education history, LinkedIn profile, and website, and the posting is powered by Greenhouse.<\/p>\n\n
