JOB SUMMARY Our Engineering Labs are where new silicon, systems, and platforms are brought to life, tested, and scaled. We’re looking for an experienced Engineering Lab Infrastructure Lead to help us build and operate the technical foundations that support this work. You will lead the Engineering Lab Support function, ensuring our labs, infrastructure, and services remain reliable, scalable, and effective for the engineers developing Graphcore’s next generation technologies. Initially, this is a highly hands-on role. You’ll work directly with engineering teams, supporting lab environments, managing infrastructure, automating workflows, and solving complex technical problems. As the function grows, you’ll help build and lead a small team while defining the processes, standards, and service model that will support the organisation long term. You’ll work closely with silicon, hardware, systems, and software engineering teams, making a direct impact on the speed and effectiveness of product development. THE TEAM You’ll be joining a multidisciplinary team with strong technical skills and a very encouraging culture. We work closely together and regularly share knowledge, and your skills will make a direct impact on our business. It’s an exciting and pivotal moment for us right now, with plenty of new projects ahead. If you're looking to solve interesting problems and see your work deliver real-world results, this is the team for you.  RESPONSIBILITIES AND DUTIES * Leading the development of Engineering Lab infrastructure and support services * Acting as the technical escalation point for complex infrastructure and lab issues * Managing Linux-based servers and engineering environments * Supporting hardware bring-up, validation, and testing activities * Designing and improving operational processes, tooling, and automation * Maintaining and improving network, storage, and compute infrastructure within engineering labs * Managing infrastructure through configuration management and Infrastructure-as-Code practices * Building strong relationships with engineering teams and understanding their evolving requirements * Developing knowledge bases, documentation, and operational standards * Recruiting, mentoring, and leading a small team of Lab Infrastructure Engineers as the function grows ESSENTIAL * Strong Linux systems administration experience across Debian and/or Red Hat environments * Experience supporting engineering, research, laboratory, HPC, or data-centre environments * Solid networking knowledge including routing, VLANs, VPNs, and troubleshooting complex connectivity issues * Experience managing physical infrastructure including servers, rack-mounted equipment, BMCs, firmware, and out-of-band management * Experience with configuration management and automation tools such as Ansible, Puppet, or similar * Familiarity with authentication and access-management systems such as LDAP, RADIUS, or Active Directory integrations * Strong troubleshooting skills with a structured and methodical approach to problem solving * Excellent communication skills and a customer-focused mindset DESIRABLE * Container technologies such as Docker, containerd, or Kubernetes * Monitoring and observability platforms such as Prometheus, Grafana, Zabbix, OpenTelemetry, or similar * Python scripting and automation * CI/CD tooling including GitLab or GitHub Actions * Experience supporting hardware development, silicon validation, embedded systems, or electronics laboratories * Performance analysis and troubleshooting across compute, storage, and network infrastructure * Web infrastructure technologies including NGINX, HAProxy, or load balancing platforms We welcome people of different backgrounds and experiences; we’re committed to building an inclusive work environment that makes Graphcore a great home for everyone. We offer an equal opportunity process and understand that there are visible and invisible differences in all of us. We can provide a flexible approach to interview and encourage you to chat to us if you require any reasonable adjustments.

Graphcore

Graphcore is a globally recognised leader in Artificial Intelligence computing systems. The company designs advanced semiconductors and data centre hardware that provide the specialised processing power needed to drive AI innovation, while delivering the efficiency required to support its broader adoption.  As part of the SoftBank Group, Graphcore is a member of an elite family of companies responsible for some of the world’s most transformative technologies. We are expending our labs in Bristol which will play a central role in Graphcore's work building the future of AI computing.   We are looking for a Validation and Debug engineer to work with Architecture, Silicon Engineering, Hardware Engineering and the Firmware team to help create and execute the Validation and debug of our cutting-edge system platforms. As such you will need to develop a detailed understanding of our silicon and platform products. Your role will be to create and execute bring-up plans of our silicon devices and platforms in systems to show that they will operate correctly over all conditions in the final product. This bring-up will also involve debugging of hardware and firmware. You will concentrate on mainly manual testing of systems in the lab with the aid of some automation. Responsibilities and Duties  * Perform Validation for new hardware platforms. * Debug PCB, power, signal integrity, and interface issues. * Support validation of high-current multi-phase SMPS power systems, including sequencing, transient response, thermal behaviour, load regulation, and power integrity analysis. * Debug complex power delivery networks supporting high-speed ASICs, FPGAs, MCUs, and accelerator devices. * Validate voltage rails, sequencing requirements, ripple, noise, efficiency, and thermal performance of multi-phase regulators. * Identify root causes and drive corrective actions across hardware and firmware domains. * Create bring-up documentation, test procedures, and debug reports.   Working closely with: * PCB design engineers * Power engineers * Signal integrity engineers * Embedded software teams   Essential skills * Hardware Validation and Debug * Multi-phase SMPS validation * Power integrity analysis * Signal integrity analysis * Root-cause analysis * Embedded systems * Cross-functional collaboration * Low-level system integration * An ability to work independently without daily oversight. * Independently performs board bring-up and subsystem debug * Drives issue resolution across teams. * Use advanced lab instrumentation including: * High-bandwidth oscilloscopes * PCIe protocol analysers * Logic analysers * Electronic loads * Power analysers * Hands-on experience with: * Multi-phase SMPS and PDN validation *   Desirable skills: * Knowledge of PCBA and system level technologies * Background knowledge of ATE systems and capabilities. You may not be directly involved with such testing. * The ability to code or script automation and data analysis using appropriate coding languages such as Python, LabView and BASH. * Experience with Renesas controllers   Benefits: In addition to a competitive salary, Graphcore offers a competitive benefits package.
