Summary
Celestica is seeking a Principal Hardware Systems Architect for Compute Platforms to provide senior technical leadership for the architecture and development of next-generation AI, accelerated computing, and high-performance data center platforms.
This role will lead compute-platform architecture spanning CPUs, GPUs and AI accelerators, memory, storage, PCIe/CXL, scale-up interconnects, and compute-node/tray architecture, while collaborating with peer domain architects and engineering leaders to define complete rack and multi-rack systems incorporating networking, power, thermal, mechanical, firmware, and system-management technologies.
This is a system and platform architecture role, not a processor or ASIC design role. The successful candidate will operate above the component level, translating customer requirements, workload needs, and technology roadmaps into scalable compute architectures.
A 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.
Skills & Responsibilities:
Compute Platform Architecture -
Define architecture for next-generation AI, accelerated-compute, server, and high-performance computing platforms.
-

-
Scale-up interconnect architecture
-
Compute node and tray architecture
-
Establish compute-system requirements, interfaces, partitioning, and architectural tradeoffs.
-
Evaluate alternatives based on performance, bandwidth, latency, power, thermal density, reliability, cost, scalability, serviceability, and manufacturability.
-
Develop reusable compute-platform architectures and building blocks that can be leveraged across customers and programs.
AI & Compute Technology Leadership -
Maintain deep technical understanding of evolving CPU, GPU, AI accelerator, memory, storage, and interconnect technologies.
-
Track and evaluate technology roadmaps from leading compute ecosystem suppliers including NVIDIA, AMD, Intel, ARM ecosystem companies, and emerging AI accelerator providers.
-
Understand emerging AI compute architectures and their implications for:
-
Accelerator density

Liquid cooling
-
Rack and cluster architecture
-
Lead architectural evaluation of scale-up technologies, including NVLink/NVSwitch-class technologies and emerging accelerator interconnects.
Integrated Rack & Multi-Rack Architecture -
Partner with peer system architects to define integrated rack and multi-rack architectures spanning compute, networking, power, thermal, mechanical, firmware, and system-management domains.
-
Optimize architecture as a complete AI system rather than as independent compute or networking platforms.
-
Partner closely with the Network Architect to establish the interface between accelerator scale-up architectures and network scale-out architectures.
-
Jointly evaluate system-level architectural tradeoffs where compute and networking intersect, including:
-
Accelerator density
-
Fabric bandwidth
-
NIC/DPU architecture
-
Switch topology
-
Latency
-
Power consumption
-
Thermal density
-
Reliability
-
Cost
-
Scalability
-
Work with Power, Thermal, Mechanical, Reliability, Firmware, and Validation engineering teams to establish system-level requirements and interfaces.
-
Drive architectural thinking from compute node ? tray ? rack ? multi-rack AI system.
Experience Requirements
Required Qualifications -
Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, Physics, or related technical field.
-
Typically 12+ years of relevant hardware and system-development experience, with significant experience in server, compute, AI, HPC, or data-center platforms.
-
Demonstrated experience defining or leading system-level architecture for complex compute platforms.
-
Strong knowledge of modern server architectures including x86 and/or ARM processors, GPaccelerators, DDR/HBM, PCIe, CXL, NVMe/storage, and high-speed interconnects.
-
Strong understanding of the relationships among compute, networking, memory, power, and thermal architecture.
-
Experience taking complex platforms from early architecture through development, validation, and production.
-
Ability to make and communicate system-level engineering tradeoffs involving performance, cost, power, thermal, reliability, and schedule.
-
Strong technical communication and presentation skills.
-
Ability to influence technical decisions across multiple engineering disciplines without relying on direct organizational authority.
-
Experience engaging directly with customers, silicon vendors, and technology partners.
Preferred Qualifications -
Experience architecting GPU-based AI training or inference platforms.
-
Experience with NVIDIA, AMD, Intel, or other accelerator-based platforms.
-
Experience with rack-scale AI systems and high-density compute architectures.
-
Knowledge of NVLink/NVSwitch-class technologies or comparable scale-up fabrics.
-
Working knowledge of high-performance Ethernet and/or InfiniBand scale-out architectures.
