Neysa Mumbai Metropolitan Region

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
- 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
