📋 Description

• Take complete ownership of the comprehensive network architecture and the multi-year strategy for data center fabric, backbone and edge, as well as cloud and hybrid connectivity.

• Design and construct spine-leaf GPU cluster fabrics to facilitate multi-node inference and training.

• Manage multi-region interconnect, transit and peering, anycast, traffic steering, DDoS protection, and edge security.

• Integrate cloud, bare-metal, and partner capacities via VPC, VPN, and private interconnect.

• Establish network monitoring protocols, change management procedures, incident runbooks, repair workflows, and on-call practices.

• Develop capacity-forecasting models and convert growth projections into bandwidth, port, interconnect, procurement, and construction plans.

• Automate network configuration, validation, rollback, provisioning, and telemetry-driven remediation.

• Leverage AI tools for design exploration, configuration generation, telemetry analysis, documentation, and automation scripting.

• Set network standards, review designs across Infrastructure, Platform, and ML Engineering, mentor engineers, and formulate the network engineering hiring strategy and operational model.

• Assess and select hardware, optics, carriers, and interconnect partners, while negotiating performance and cost.

• Report directly to the Head of AI Infrastructure; initially, there will be no direct reports.

⛳️ Requirements

• Over 15 years of experience in network engineering and architecture, including a minimum of 5 years serving as the design authority for large-scale production networks at a cloud provider, hyperscaler, CDN, HPC/AI infrastructure company, or carrier.

• Practical experience in designing, configuring, and troubleshooting networks.

• Proven track record in building data center, backbone, and cloud networks from the ground up.

• In-depth expertise in spine-leaf Clos fabrics, EVPN/VXLAN, BGP at scale, 400G/800G Ethernet, RoCEv2, lossless Ethernet, PFC, ECN, DCQCN, and InfiniBand for GPU clusters.

• Experience with backbone and edge, involving multi-region interconnect, transit and peering, anycast, traffic engineering, and DDoS mitigation.

• Proficiency in cloud and hybrid networking across at least two hyperscalers, along with bare-metal or colocation environments.

• Familiarity with VPC design, private interconnect, and VPN at scale.

• Knowledge of designing and managing network operations, including observability, change management, incident response, and on-call duties.

• Demonstrated experience in capacity planning and the procurement cycle.

• Experience with network automation using Python or Go, infrastructure as code, CI-style validation, and streaming telemetry.

• Proven use of AI tools for network design, configuration, automation scripting, telemetry analysis, and documentation.

• Experience in leading high-performance engineering teams, including hiring, establishing standards, and influencing others.

• Strong sense of ownership and ability to thrive in a fast-paced, ambiguous environment.

• Must be based in, or able to maintain full working overlap with, US Pacific time.

• Notable differentiators include expertise in GPU cluster networking, modern network operating systems, disaggregated hardware, emerging fabric technologies, peering and transit operations, eBPF, DPDK, SmartNICs/DPUs, kernel-bypass networking, and prior experience in startups or scale-ups, as well as public technical contributions.
