We design advanced semiconductors, software, and data center infrastructure that provide the specialized processing power needed to advance AI while improving the efficiency required for broad adoption.\nAs part of SoftBank Group, Graphcore belongs to a family of companies developing progressive technologies. Our teams bring together AI researchers, silicon designers, software engineers, and systems architects to solve sophisticated technical problems across the computing stack.\nThe Opportunity\nAs Principal Security Architect, you will define and lead the end-to-end hardware and firmware security strategy for Graphcore's next-generation AI server systems powered by Arm technology. You will establish security architecture across the system, from the system-on-chip and management controllers through firmware, virtualization, and container environments.\nWorking within Advanced Architecture, you will protect AI models, training data, inference workloads, and platform intellectual property against remote, physical, and supply-chain threats. You will set technical direction, translate threat models into engineering requirements, and guide teams in delivering hardware-backed isolation, verified boot, secure lifecycle management, and attestation.\nWhat You Will Do\nDefine the hardware and firmware security architecture for Arm-based AI server platforms and maintain a coherent security model across silicon, boards, firmware, virtualization, and system software.\nLead the build and integration of Arm's secure computing framework and Realm Management Extension technologies to protect AI models and data in use from operating systems, hypervisors, and other tenants. \nDefine platform, Baseboard Management Controller, and Rack Management Controller trust anchors, including secure boot, secure firmware update, device identity, provisioning, cryptographic key management, and lifecycle controls. \nSpecify security requirements for high-speed interfaces and interconnects, including PCIe Gen5 and Gen6 and NVMe Storage Integrity and Data Encryption, to protect data moving among CPUs, AI accelerators, storage, and memory.\nLead system-level threat modeling and define mitigations for side-channel attacks, fault injection, privilege escalation, physical tampering, and supply-chain risks.\nGuide the design and hardening of UEFI, Arm Trusted Firmware, OpenBMC, and related low-level software, including device authentication based on the Security Protocol and Data Model.\nArchitect runtime audit, measurement, and remote attestation frameworks that provide verifiable evidence of platform identity, configuration, and software state.\nTranslate security goals into clear engineering specifications, design requirements, assurance criteria, and review processes for hardware and software teams.\nPartner with silicon, hardware, firmware, networking, and systems teams to resolve security tradeoffs, review designs, and incorporate security requirements into technology roadmaps.\nEvaluate emerging threats, standards, and technologies, and represent Graphcore's technical requirements in relevant open-source and industry communities where appropriate.\nWhat You Will Bring\nAn advanced degree or equivalent experience in computer science, computer engineering, cryptography, cybersecurity, or a related technical field, or equivalent practical experience.\nExtensive experience in hardware security, system-on-chip security, platform architecture, or a closely related field, including technical leadership at Principal, Staff, or Lead Architect scope.\nDeep knowledge of Arm architecture and security technologies, including Armv9, TrustZone, Confidential Compute Architecture, and the Realm Management Extension feature. \nDemonstrated experience in crafting server or platform security frameworks that use trusted platform modules, roots of trust, hardware cryptography, secure provisioning, and lifecycle management. \nStrong understanding of how hardware security primitives interact with firmware and system software, including Linux kernel internals, KVM, containers, and trusted execution environments.\nExpert knowledge of hardware and platform threats, physical attack methods, side-channel risks, fault injection, and supply-chain vulnerabilities.\nExperience with secure boot, firmware update security, cryptographic key management, device identity, attestation, and audit design.\nAbility to convert complex security concepts and threat analyses into precise, testable engineering requirements and architecture decisions.\nProven track record to lead multi-functional technical work and influence senior engineers and leaders without direct authority.\nClear written and verbal communication skills, including the ability to explain risk, tradeoffs, and recommended controls to technical and executive audiences.\nPreferred Qualifications\nThese qualifications are helpful, not required. We encourage you to apply even if you do not meet every preferred qualification.\nExperience designing security architectures that protect machine learning weights, intellectual property, and datasets during distributed training and inference.\nParticipation in or contributions to security standards and industry groups such as the Trusted Computing Group, Open Compute Project Security Project, Linux Foundation, Confidential Computing Consortium, or Arm security working groups.\nKnowledge of SmartNIC security and the use of network devices to enforce network or storage isolation within server systems.\nUnderstanding of post-quantum cryptography and its implications for hardware lifecycle, trusted startup processes, firmware, and silicon build. \nExperience applying emerging confidential-computing technologies to AI training or inference use cases.\nUnited States Benefits Overview\nGraphcore offers competitive compensation and benefits designed to support employees' health, financial well-being, work-life needs, and professional growth. Benefits and programs for eligible U.S. employees may include:\nMedical, dental, and vision coverage, with options that may extend to eligible dependents.\nMental health, wellness, and employee assistance resources.\nRetirement savings benefits and company contributions where applicable.\nPaid vacation, sick time, company holidays, and parental or family leave in accordance with relevant plans and policies. \nLife insurance and short-term or long-term disability coverage.\nFlexible working hours and hybrid working arrangements where compatible with the role and team requirements.\nProfessional-development resources, learning programs, office amenities, and team-led activities.\nBenefits vary by work location, employment status, scheduled hours, and plan eligibility and are subject to the terms of the applicable plans and company policies. This overview is not a contract or guarantee of benefits.\nEqual Opportunity and Accommodations\nGraphcore is an equal opportunity employer.
