[Hiring] Principal Engineer, Hardware Design @Celestica International LP

Role Description

Celestica is seeking a Principal Hardware Systems Architect for Networking Platforms to provide senior technical leadership for the architecture and development of next-generation AI, cloud, and high-performance data center networking platforms. This role will lead networking-platform architecture spanning:

• High-performance Ethernet and InfiniBand-class fabrics
• Switching systems
• NICs/DPUs
• High-speed SerDes
• Optical and electrical interconnects
• Scale-out network architectures

The successful candidate will operate above the component level, translating customer requirements, technology roadmaps, and AI workload needs into scalable networking-platform architectures. A critical aspect of the position is understanding that next-generation AI networking cannot be optimized independently from compute. The Network Architect will partner closely with Celestica’s Compute Architect and other domain experts to optimize the complete AI system from compute connectivity through rack and multi-rack network fabrics.

Qualifications

• BS or MS in Electrical, Computer Engineering, Computer Science, Physics, or a related field.
• Typically 12+ years in hardware development with strong focus on networking, switching, AI, or cloud platforms.
• Proven experience defining system architecture for complex networking platforms.
• Deep knowledge of Ethernet/InfiniBand, switch architectures, NICs/DPUs, PCIe, SerDes, and optical/electrical interconnects.
• Strong understanding of switching NPUs/ASICs, CPUs, accelerators, PCIe/CXL, and system integration.
• Solid grasp of networking, compute, power, thermal, and mechanical architecture interplay.
• Track record of taking complex platforms from early architecture to production.
• Ability to evaluate tradeoffs across bandwidth, latency, cost, power, thermal, reliability, and schedule.
• Excellent technical communication and presentation skills.
• Proven ability to influence cross-functional technical teams without direct authority.
• Direct experience engaging with customers, silicon vendors, and partners.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, Physics, or related technical field.
• Architecting networking systems for large-scale AI training or inference clusters.
• High-performance Ethernet or InfiniBand architectures.
• Modern switching silicon, NIC, SmartNIC, SuperNIC, or DPU technologies.
• 800G, 1.6T, and next-generation high-speed networking.
• Advanced optics and evolving electrical/optical interconnect architectures.
• GPU scale-up fabrics and accelerator interconnect architectures.
• Rack-scale and multi-rack AI infrastructure.
• High-power, liquid-cooled networking or compute systems.
• Collaboration with hyperscale or cloud service provider customers.
• Developing reusable platform architectures.
• Contributing to roadmaps, standards, patents, or advanced development.
