We are representing a confidential AI infrastructure organization seeking a Principal Network Engineer to lead technical direction for their high-performance GPU cloud environment.

You will own critical network domains end-to-end, including:

• Defining and validating large-scale InfiniBand, RoCE, and Ethernet fabric architectures at rack, row, and data centre scale
• Designing high-performance Ethernet fabrics with BGP, EVPN, VXLAN, LACP, and QoS
• Establishing reference architectures and engineering standards for consistent implementation across multiple data centre sites
• Leading network automation strategy using GitOps operating models with Python and Ansible
• Building version-controlled configuration and CI/CD-based network change across multi-vendor environments
• Designing perimeter and network security infrastructure including firewalls, NAT, VPN, and multi-tenant segmentation
• Leading complex technical escalations and root-cause analysis for network performance and reliability issues
• Establishing SLOs and operational standards for network services with comprehensive observability
• Partnering with deployment, operations, platform engineering, systems, storage, and vendor teams on site delivery and platform evolution
• Mentoring engineers and leading architecture reviews for significant network initiatives

What We're Looking For

Required Experience:

• 10+ years of network engineering experience with significant depth in HPC, AI, hyperscale, or large-scale data centre environments
• Extensive hands-on experience with RDMA-aware networking for AI/HPC workloads, including InfiniBand and/or RoCE
• Experience with subnet managers and fabric orchestration technologies such as OpenSM or NVIDIA UFM
• Expert-level understanding of modern data centre routing and control planes, including BGP, EVPN-VXLAN, and Clos/spine-leaf architectures
• Production experience with network platforms such as Cumulus, Nokia, or Arista EOS
• Strong network automation expertise using Python and Ansible
• Experience with Git-based workflows and Infrastructure-as-Code tooling such as Terraform, GitLab CI, or GitHub Actions
• Deep experience designing firewall infrastructure using platforms such as Juniper SRX and/or Palo Alto
• Experience designing telemetry and observability solutions for high-throughput, performance-sensitive environments
• Proven ability to lead complex technical decisions and incidents across multiple engineering disciplines

Leadership & Architecture:

• Demonstrated experience defining network architecture, engineering standards, and technical strategy beyond a single project or data centre
• Ability to balance performance, reliability, operability, scalability, and delivery velocity when making technical decisions
• Experience influencing engineering teams and technical direction without formal authority
• Strong communication skills with the ability to explain complex technical trade-offs to engineers, operators, and senior stakeholders
• Proven ability to mentor and develop other engineers through design reviews, technical guidance, and knowledge sharing

Personal Attributes:

• Deeply technical and comfortable remaining hands-on at Principal level
• Highly analytical with a structured approach to solving complex infrastructure problems
• Strong sense of ownership and accountability
• Comfortable operating in a fast-paced environment where priorities evolve quickly
• Pragmatic and able to balance architectural excellence with business requirements
