Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Hardware System Product Engineer - **Company:** Fractile - **Location:** Bristol, UK - **Experience:** Experienced - **Contract:** Permanent contract - **Skills:** Testing (Software), Artificial Intelligence, Software Debugging, Linux, PCI Express, Software Engineering, System Testing, Management of Software Versions, Hardware Testing, Hardware Infrastructure - **Published:** August 30, 2026 - **Apply:** https://www.collegerecruiter.com/job/2815117912-hardware-system-product-engineer ## About the Role * 3-7 years of experience in system, server, or hardware test engineering, preferably in manufacturing or service environments. * Solid understanding of server hardware architectures, PCIe fabrics, power delivery, cooling systems, and common failure modes. * Hands-on experience developing or executing hardware defect detection or diagnostic tests. * Experience working in Linux-based test environments. * Familiarity with BMC-based systems and basic use of OpenBMC or Redfish interfaces. * Strong debug skills and the ability to distinguish test issues from real hardware faults. * Ability to write clear test code, logs, and documentation for operational use., * Experience with AI accelerator, GPU, or high-performance compute servers. * Exposure to PCIe Gen4/5/6 systems or other high-speed serial interconnects. * Experience diagnosing intermittent, marginal, or temperature-dependent hardware failures. * Experience working with liquid-cooled or thermally complex server platforms. ## Description We're looking for an engineer to develop and maintain system-level hardware defect detection tests for an AI accelerator server platform. The role is focused on implementing, executing, and improving tests used in factory assembly and service/repair environments to identify hardware defects quickly and reliably. Work closely with the System Test Engineering Lead to translate defect detection strategy into robust, repeatable test implementations rather than design validation., * Develop and maintain system-level hardware defect detection tests for individual servers and rack-based systems. * Implement tests to detect assembly defects, marginal components, damaged hardware, cabling or interconnect issues, cooling faults, etc. * Develop service and field diagnostic tests used for RMA triage, repair validation, and preventative maintenance. * Implement deterministic, fast-running tests with clear pass/fail criteria and actionable failure output suitable for manufacturing and service technicians. * Develop PCIe defect detection tests to identify lane faults, link degradation, polarity issues, retimer problems, and intermittent connectivity failures. * Implement stress and soak tests designed to expose latent or marginal hardware issues. * Debug test failures and hardware issues, performing root-cause analysis and escalating design or process issues as appropriate. * Analyze factory and field failure data to identify coverage gaps and propose test improvements. * Support deployment, versioning, and maintenance of test software across factory and service environments. * Collaborate with software development teams to integrate tests into production system software. * Collaborate with hardware, manufacturing, service, and reliability teams to ensure tests align with known defect modes and operational needs., * 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 there * Team 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 ## Related Videos - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [How To Test A Ball of Mud](https://www.wearedevelopers.com/videos/173-how-to-test-a-ball-of-mud) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Breaking the Hardware Mindset: Overcoming Barriers to System-Level Innovation](https://www.wearedevelopers.com/videos/1635-breaking-the-hardware-mindset-overcoming-barriers-to-system-level-innovation) - [How I Built QA from Scratch in a Scaling Startup - no fluff real life story](https://www.wearedevelopers.com/videos/2041-how-i-built-qa-from-scratch-in-a-scaling-startup-no-fluff-real-life-story) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025)
