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) · Strong 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 · Ethernet lossless networking concepts (PFC, ECN, DCQCN, RoCEv2) · InfiniBand networks for HPC: configuration, troubleshooting, and performance optimization in large-scale environments · Linux networking knowledge Automation & Infrastructure-as-Code · Expert-level Python scripting for network automation and tooling · Extensive experience with Ansible, Salt, or equivalent infrastructure automation frameworks · Ability to develop CI/CD pipelines for network infrastructure provisioning and testing · Git version control and Infrastructure-as-Code practices · Lab environment simulation and topology validation using NVIDIA Air, GNS3, EVE-NG, or similar tools Ways to stand out from the rest: · Networking certifications: Cisco, Arista, Nokia, Nvidia or equivalent · Linux Certifications · Kubernetes and Docker; container networking · Cloud networking: AWS, GCP, Azure; hybrid cloud and on-premises integration · Personal GitHub repository with Python examples and evidence of coding expertise Minimum Qualifications: Bachelor’s degree in computer science, Electrical/Computer Engineering, Physics, Mathematics, or related field (or equivalent industry experience) years of networking fundamentals and data center architecture · 5+ years of hands-on EVPN/BGP/VXLAN experience · Proficiency in at least one major platform (Arista, Cumulus, SONiC, Juniper, Cisco) · Production troubleshooting experience.
Soft Skills: · Strong problem-solving and debugging abilities · Ownership mindset with accountability for deployment quality and customer success · Cross-functional collaboration with other teams · Proactive approach to continuous learning and staying current with AI infrastructure trends · Strong documentation and presentation skills, with ability to defend design decisions in peer reviews.
