Principal Engineer, Hardware Design - Networking

About the role

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.

Responsibilities

• Define architecture for next-generation AI, cloud, hyperscale, and high-performance data center networking platforms.
• Own architectural definition of:
  • High-performance Ethernet and InfiniBand-class networking
  • Switch architectures
  • NIC, SmartNIC, SuperNIC, and DPU architectures
  • High-speed SerDes
  • Optical and electrical interconnects
  • Scale-out network fabrics
  • Network topology
  • Inter-rack connectivity
• Establish networking-system requirements, interfaces, partitioning, and architectural tradeoffs.
• Evaluate alternatives based on bandwidth, latency, congestion, power, thermal density, reliability, cost, scalability, serviceability, and manufacturability.
• Develop reusable networking-platform architectures and building blocks that can be leveraged across customers and programs.
• Lead early architecture studies, feasibility assessments, proof-of-concept development, and platform definition.

Requirements

• 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.
• Able to evaluate tradeoffs across bandwidth, latency, cost, power, thermal, reliability, and schedule.
• Excellent technical communication and presentation skills.
• Prominent ability to influence cross-functional technical teams without direct authority.
• Direct experience engaging with customers, silicon vendors, and partners.

Skills

• 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.
