Staff Network Engineer – AI Infrastructure

This is a fully remote position, open to applicants in Europe.

📋 Description

• Develop and implement systems that automatically provision and configure NVIDIA switches and InfiniBand fabrics, including integration with NVIDIA UFM.

• Construct the control loop that maintains the consistency of switch, VLAN, and VXLAN states with platform intentions, identifies drift, and safely resolves it in production.

• Create the NAT gateway and L4 load-balancing layer for tenant-cluster connectivity, ensuring failover capabilities.

• Define network-layer behaviors at scale, including limitations on BGP route-tables, convergence, failover, and handling link, switch, or gateway failures.

• Execute automation in real AI Cloud environments, identify failures, and transform operational insights into product functionalities.
