• Monitor and optimize network performance for east-west traffic and high-throughput AI workloads.
• Support RoCEv2 networking and lossless Ethernet configurations for GPU clusters.
• Automate network operations using Ansible, Python, and APIs.
• Troubleshoot routing, switching, and latency issues across data center environments.
• Collaborate with Linux, Kubernetes, and infrastructure teams to support AI platforms.
• Develop operational procedures and maintain network documentation.
• Participate in customer deployments and provide remote support when needed.

Required Qualifications

• 2-3+ years of experience in data center networking.
• Hands-on experience with Cisco, NVIDIA or SONiC (Software for Open Networking in the Cloud).
• Hands-on experience with Fortinet or other firewall products
• Strong understanding of:
• Layer 2 and Layer 3 networking
• BGP and EVPN
• VXLAN overlays
• ECMP
• Spine-leaf architectures
• High availability and redundancy
• Experience with white-box switches from vendors such as Edgecore, Celestica, Dell, or Supermicro.
• Solid understanding of Ethernet switching and routing protocols.
• Experience with Linux networking fundamentals.
• Familiarity with packet analysis tools and troubleshooting methodologies.
• Strong scripting or automation skills using Python, Bash, or Ansible.
• Ability to work independently in a fast-paced startup environment.

Preferred Qualifications

• Experience with AI and GPU clusters utilizing NVIDIA Spectrum or ConnectX networking.
• Familiarity with RoCEv2, PFC, ECN, and congestion management.
• Experience with Cumulus Linux, Arista EOS, Cisco NX-OS, or Juniper.
• Knowledge of Kubernetes and container networking.
• Experience with Mellanox/NVIDIA networking solutions.
• Familiarity with telemetry and observability tools such as Prometheus, Grafana, and NetBox.
• Experience with cloud networking and hybrid infrastructure.
• Understanding of RDMA and high-performance computing environments.

Nice to Have

• CCNP, CCIE, JNCIP, or equivalent networking certifications.
• Experience operating networks for AI factories, HPC clusters, or cloud providers.
• Contributions to SONiC, FRR, or open networking communities.
• Familiarity with network automation frameworks and GitOps workflows.
