About the role

Lead the design and evolution of Cerebras's networks across data centers, offices, and cloud environments, setting architectural direction for high-performance, secure, and scalable networking in a hyperscale AI infrastructure.

Responsibilities

  • Define and own the architectural roadmap for Cerebras's enterprise, data center, and cloud network estate.
  • Co-author secure design and lifecycle management of high-performance data center networking — including spine/leaf, RDMA, and high-bandwidth fabrics supporting wafer-scale compute.
  • Build and maintain an AI-agent based analysis and review framework for network changes as well as self-improvement driven by observed network patterns and use cases.
  • Partner with Network Security to deliver segmented, zero-trust-aligned network designs across data center and corporate environments.
  • Set standards for resiliency, observability, and capacity planning across the global network
  • Mentor engineers across regions (US, Canada, Bangalore, and beyond), and serve as the senior technical voice on cross-functional network initiatives.
  • Stay ahead of emerging networking patterns relevant to AI infrastructure and translate them into actionable architecture decisions.

Qualifications

  • 10+ years of experience in enterprise and/or data center network engineering, including hands-on design and operations at scale.
  • Deep understanding in cloud networking and service mesh, with emphasis on K8s service mesh and virtual networks.
  • Deep expertise in routing, switching, and data center fabrics — including BGP, EVPN/VXLAN, and high-bandwidth/low-latency designs.
  • Hands-on experience with networking for high-performance compute or AI/ML workloads (RDMA, RoCE, InfiniBand exposure a plus).
  • Strong proficiency with network automation — infrastructure as code (Ansible, Terraform), version-controlled configuration, and CI/CD for network change.
  • Working knowledge of cloud networking (AWS preferred), including VPCs, transit gateways, Direct Connect, and hybrid connectivity patterns.
  • Experience operating networks at multi-site, global scale — including capacity planning, incident response, and vendor management.
  • Excellent written and verbal communication skills, with the ability to lead architecture conversations across technical and non-technical audiences.
