Job Title: Senior Network Engineer

Location: Mumbai

Experience: 7+ years (including 5+ years hands-on with EVPN, BGP, and VXLAN)

We’re hiring a Senior Network Engineer for our client, an AI Cloud company helping enterprises build, scale, and govern AI in production.

As the Senior Network Engineer, your responsibilities would be:

• Design, build, and operate hyperscale EVPN-VXLAN Clos/Leaf-Spine Ethernet fabrics and InfiniBand networks for GPU clusters and HPC workloads.

• Own the complete network lifecycle, from requirements gathering and architecture design to lab validation, deployment, and day-to-day operations.

• Deploy and tune lossless Ethernet (RoCEv2, PFC, ECN, DCQCN) and host-side Linux networking to ensure predictable, zero-loss performance for AI training and inference.

• Develop robust network automation pipelines and Infrastructure-as-Code practices using Python, Ansible, and Git.

• Monitor network health, diagnose complex production issues at the packet level, and collaborate with vendors for rapid issue resolution.



Requirements

• 7+ years of experience in networking fundamentals and data center architecture, with at least 5 years of hands-on experience with BGP, OSPF, EVPN, and VXLAN.

• Strong expertise in Clos/Leaf-Spine fabric design, multi-tier network topologies, and capacity planning.

• Hands-on proficiency configuring, testing, and validating major network platforms (Arista EOS, Cumulus Linux, SONiC, Juniper, Cisco, or Nokia SR Linux) in production.

• Practical knowledge of lossless Ethernet (RoCEv2, PFC, ECN, DCQCN) and InfiniBand interconnects for GPU/AI or HPC workloads.

• Advanced network automation skills using Python, Ansible (or Salt), and Git-based CI/CD workflows.

• Strong understanding of Linux networking, packet-level troubleshooting, and topology simulation tools (NVIDIA Air, GNS3, or EVE-NG).



Benefits


• Build foundational hyperscale network infrastructure powering production AI clouds for leading enterprises, startups, and research institutions.

• Solve complex, cutting-edge engineering problems at scale across lossless RDMA fabrics, InfiniBand, and massive GPU clusters.

• Work directly alongside and learn from seasoned industry pioneers who founded NetScaler and Netmagic.

• Enjoy end-to-end ownership across architecture, automated deployment, and production operations.

• Be part of an engineering-first culture focused on high ownership, technical craftsmanship, and continuous learning.
