About the Role
We're building AI/HPC infrastructure that powers the next generation of high-performance computing. As a Network Engineer, you'll responsible to design, build, and operate large-scale network fabrics that support GPU clusters, HPC workloads, and mission-critical AI systems. You'll engage across the full lifecycle—from requirements gathering and architecture design through deployment, optimization, and operational support. This is hands-on infrastructure work.
What you'll be doing:
· Design and deploy EVPN-VXLAN Clos/Leaf-Spine Ethernet fabrics and InfiniBand networks for high-performance computing environments
· Configure and troubleshoot BGP, OSPF, VXLAN, and EVPN protocols across multi-vendor platforms (Arista, Cumulus, SONiC, Juniper, Cisco)
· Deploy lossless fabrics (Ethernet and InfiniBand) which use RDMA technologies for high-performance computing.
· Build and validate network topologies in lab environments using simulation tools (NVIDIA Air, GNS3, EVE-NG)
· Develop and optimize network automation solutions using Python and Ansible for network infrastructure
· Support operational excellence: monitor network health, troubleshoot production issues, and coordinate with vendors for rapid resolution
· Create comprehensive documentation, operational runbooks, and knowledge bases for customer support and knowledge transfer
What we need to see:
Core Networking (10+ years)
· Deep expertise in TCP/IP stack, Layer 2/3 switching, routing, and data center architecture
· Expert-level knowledge of BGP, OSPF, EVPN, and VXLAN (5+ years hands-on experience)
· Robust understanding of Clos/Leaf-Spine fabric design and multi-tier network architectures
· Advanced network troubleshooting using packet sniffers, analysis tools, and diagnostic techniques
· Hands-on with at least one network operating system viz. Arista EOS, Cumulus Linux, Cisco, Nokia SR Linux etc.
· Configuration, testing, validation, and issue resolution on these platforms in production environments
