Requirements
- 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.
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.
