What you will do

• Design and evolve resilient inter-site, cloud, and internet connectivity for large-scale AI infrastructure.
• Own external BGP policy and edge traffic engineering, including route filtering, failover, and capacity planning.
• Build API-driven automation for routing, firewalls, VPNs, carrier connectivity, and network segmentation.
• Coordinate with carriers, cloud connectivity providers, colocation partners, and vendors on provisioning, incidents, and service improvements.
• Design automated validation, resilience testing, staged rollouts, observability, rollback, and recovery workflows.
