Job summary

Netris, Inc. in Santa Clara, CA is seeking a Network Architect with deep hands-on experience in modern datacenter networking. You will design, build, automate, and debug EVPN/VXLAN fabrics, and work on Arista EOS and SONiC on Linux-based networks.

You will troubleshoot across control and data planes, translate requirements into precise configurations, and collaborate with engineering and operations to deliver scalable, reliable AI cloud networks.

Qualifications

• Strong hands-on experience with datacenter EVPN/VXLAN fabrics and underlay/overlay in large-scale environments.
• Ability to translate network requirements into precise Arista EOS and SONiC configurations.
• Deep troubleshooting across control and data planes (BGP EVPN, VXLAN, Linux networking).

Responsibilities

• Design and evolve EVPN/VXLAN fabrics for L2/L3, multi-tenant environments.
• Create and validate configuration blueprints for Arista EOS and SONiC.
• Operate networking platforms, including Linux stack, iproute2, nftables/iptables, VRFs and bridges.
• Troubleshoot complex issues in both underlay and overlay networks.
• Collaborate with engineering and operations to deliver reliable, scalable solutions.
• Review designs and enforce accuracy, determinism and fault-handling.

Shape the AI buildout

Join the team shaping the networking foundation behind the world's most demanding AI clouds.

Network Architect – Arista EOS & SONiC

About Netris

Netris is the leading network automation platform for AI clouds. AI is the largest infrastructure buildout in history, and networking is its bottleneck. Netris is the automation and multi-tenancy layer for AI cloud networking, enabling operators to launch GPU clouds in weeks, provision tenants instantly, and maximize GPU utilization. The company experienced 800% ARR growth in the last 12 months, with 60+ live GPU cluster deployments globally and growing, and is backed by Andreessen Horowitz. SDN reinvented data center networking, and Netris is doing it for the AI cloud with NAAM: Network Automation, Abstraction, and Multi-Tenancy.

The role

We are looking for a strong Network Architect with deep hands-on expertise in modern datacenter networking. This role is for someone who designs, builds, automates and debugs complex EVPN/VXLAN fabrics down to the packet level, not just configures them. You will work on high-performance, Linux-based networking stacks and next-generation datacenter architectures, with a strong focus on correctness, scalability and operational excellence.

What you’ll do

• Design, implement and evolve EVPN/VXLAN datacenter fabrics (L2/L3, symmetric/asymmetric IRB, multi-VRF, multi-tenant)
• Translate network requirements into clear specifications and precise Arista EOS and SONiC configuration blueprints
• Configure and operate networking platforms based on Arista EOS and SONiC, including the Linux networking stack (iproute2, netlink, nftables/iptables, bridges, VRFs)
• Perform deep troubleshooting across the control plane and data plane (BGP EVPN, VXLAN, Linux kernel networking, ASIC behavior)
• Work with BGP at expert level in both the underlay and overlay (EVPN, route targets, policy, scale considerations)
• Architect and validate high-scale datacenter network designs, including lossless fabrics for AI/ML workloads
• Collaborate with engineering, automation and operations teams to build reliable, repeatable network solutions
• Review designs and configurations with a strong emphasis on accuracy, determinism and failure handling

What we’re looking for

• Core networking protocols: L3 routing and L2 switching
• EVPN/VXLAN spine-leaf architectures, with MP-BGP in the underlay and the overlay
• Hands-on experience with Arista EOS and/or SONiC
• Ability to translate network requirements into clear specifications and precise Arista EOS or Broadcom SONiC configuration blueprints
• Knowledge of Arista EOS architecture and/or SONiC architecture and microservices
• Strong troubleshooting, analytical and problem-solving skills, including Arista EOS and/or SONiC troubleshooting tools (Linux shell, tcpdump, Docker, sonic-cli, redis-cli)

Preferred qualifications

• Lossless network architecture: low-latency AI/ML and storage workloads over RoCEv2 (PFC, ECN, DCQCN)
• Dynamic and adaptive routing
• Familiarity with switch silicon architecture, preferably Broadcom: how the FIB is programmed in hardware, TCAMs and packet buffer pools

Compensation, benefits, logistics

• Competitive salary + meaningful equity
• Full time
• Medical, vision, dental, 401(k), disability insurance, flexible PTO (US; benefits vary by location)
• Location: Santa Clara, CA preferred. For the right candidate, EMEA or APAC is also possible.
