Principal Network Engineer

You will set the technical direction for AI interconnect networks and evolve large-scale InfiniBand and RoCE fabrics. You will lead complex incident investigations, define network standards, improve reliability and performance, influence system design, and mentor network engineers.

Responsibilities

• Own the technical direction and operational strategy for AI interconnect networks
• Design, review, and evolve InfiniBand and RoCE fabric architectures
• Lead complex network incident investigations and systemic fixes
• Improve fabric reliability, performance predictability, and operational maturity
• Define hardware, congestion-control, routing, firmware, and change-safety standards
• Influence end-to-end system design with SRE, compute, and network architecture stakeholders
• Mentor senior and mid-level network engineers
• Improve uptime, latency consistency, capacity efficiency, and incident reduction

Requirements

• At least 10 years of network-engineering experience focused on HPC, AI, or hyperscale data-centre networking
• Expert operational and architectural experience with InfiniBand or large-scale RoCE fabrics
• Understanding of RDMA internals, congestion management, and fabric failure modes
• Expertise with BGP, OSPF, and ECMP
• Ability to debug cross-layer hardware, firmware, kernel, and application communication-library issues
• Ability to lead complex technical initiatives across teams
• Systems-level understanding of performance, reliability, scalability, and operational cost

Benefits

• Equity
