The successful candidate will operate above the component level, translating customer requirements, workload needs, and technology roadmaps into scalable compute architectures.\nA critical aspect of the position is understanding that next-generation AI infrastructure can no longer be optimized as independent compute, networking, power, and cooling subsystems. The Compute Architect will partner closely with Celestica’s Network Architect and other domain experts to optimize the complete AI system from compute node through rack and multi-rack deployments.\nSkills & Responsibilities:\nCompute Platform Architecture\nDefine architecture for next-generation AI, accelerated-compute, server, and high-performance computing platforms.\n\nOwn architectural definition of:\nCPU architectures\n\nGPU and AI accelerator subsystems\n\nMemory and HBM architectures\n\nPCIe and CXL fabrics\n\nLocal storage and NVMe architectures\n\nGPU/accelerator topology\n\nScale-up interconnect architecture\n\nCompute node and tray architecture\n\nEstablish compute-system requirements, interfaces, partitioning, and architectural tradeoffs.\n\nEvaluate alternatives based on performance, bandwidth, latency, power, thermal density, reliability, cost, scalability, serviceability, and manufacturability.\n\nDevelop reusable compute-platform architectures and building blocks that can be leveraged across customers and programs.\n\nAI & Compute Technology Leadership\nMaintain deep technical understanding of evolving CPU, GPU, AI accelerator, memory, storage, and interconnect technologies.\n\nTrack and evaluate technology roadmaps from leading compute ecosystem suppliers including NVIDIA, AMD, Intel, ARM ecosystem companies, and emerging AI accelerator providers.\n\nUnderstand emerging AI compute architectures and their implications for:\nAccelerator density\n\nMemory bandwidth\n\nPCIe/CXL connectivity\n\nScale-up fabrics\n\nScale-out networking\n\nRack power\n\nLiquid cooling\n\nRack and cluster architecture\n\nLead architectural evaluation of scale-up technologies, including NVLink/NVSwitch-class technologies and emerging accelerator interconnects.\n\nIntegrated Rack & Multi-Rack Architecture\nPartner with peer system architects to define integrated rack and multi-rack architectures spanning compute, networking, power, thermal, mechanical, firmware, and system-management domains.\n\nOptimize architecture as a complete AI system rather than as independent compute or networking platforms.\n\nPartner closely with the Network Architect to establish the interface between accelerator scale-up architectures and network scale-out architectures.\n\nJointly evaluate system-level architectural tradeoffs where compute and networking intersect, including:\nAccelerator density\n\nFabric bandwidth\n\nNIC/DPU architecture\n\nSwitch topology\n\nLatency\n\nPower consumption\n\nThermal density\n\nReliability\n\nCost\n\nScalability\n\nWork with Power, Thermal, Mechanical, Reliability, Firmware, and Validation engineering teams to establish system-level requirements and interfaces.\n\nDrive architectural thinking from compute node → tray → rack → multi-rack AI system.\n\nExperience Requirements\nRequired Qualifications\nBachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, Physics, or related technical field.\n\nTypically 12+ years of relevant hardware and system-development experience, with significant experience in server, compute, AI, HPC, or data-center platforms.\n\nDemonstrated experience defining or leading system-level architecture for complex compute platforms.\n\nStrong knowledge of modern server architectures including x86 and/or ARM processors, GPUs/accelerators, DDR/HBM, PCIe, CXL, NVMe/storage, and high-speed interconnects.\n\nStrong understanding of the relationships among compute, networking, memory, power, and thermal architecture.\n\nExperience taking complex platforms from early architecture through development, validation, and production.\n\nAbility to make and communicate system-level engineering tradeoffs involving performance, cost, power, thermal, reliability, and schedule.\n\nStrong technical communication and presentation skills.\n\nAbility to influence technical decisions across multiple engineering disciplines without relying on direct organizational authority.\n\nExperience engaging directly with customers, silicon vendors, and technology partners.\n\nPreferred Qualifications\nExperience architecting GPU-based AI training or inference platforms.\n\nExperience with NVIDIA, AMD, Intel, or other accelerator-based platforms.\n\nExperience with rack-scale AI systems and high-density compute architectures.\n\nKnowledge of NVLink/NVSwitch-class technologies or comparable scale-up fabrics.\n\nWorking knowledge of high-performance Ethernet and/or InfiniBand scale-out architectures.\n\nExperience with advanced liquid-cooled compute platforms.\n\nExperience with high-power rack architectures reaching hundreds of kilowatts per rack.\n\nExperience working with hyperscale or cloud-service-provider customers.\n\nExperience developing reusable platform architectures.\n\nExperience contributing to technology roadmaps, invention disclosures, patents, or advanced-development programs.\n\nTypical Education\nBachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, Physics, or related technical field.\nEducational Requirements may vary by Geography\nNotes\nThis job description is not intended to be an exhaustive list of all duties and responsibilities of the position.
