Crusoe is looking for a Principal Network Architect to define and own the network architecture strategy across our entire infrastructure stack, spanning bare-metal data center switching fabrics and RDMA interconnects to SDN control planes, Kubernetes networking, and cloud-layer overlays. As the industry's first vertically integrated AI infrastructure provider, Crusoe operates at a scale that few companies can match, including a 1.2 GW hyperscale campus in Abilene, TX powering the Stargate project. This is a high-impact, principal-level individual contributor role reporting directly to the Director of Networking, with broad technical authority and cross-organizational influence
In this role, you'll do more than solve today's problems; you'll build the architecture that runs the AI infrastructure of tomorrow. You'll introduce and institutionalize modern networking paradigms like intent-based networking, declarative configuration management, and network source of truth, transforming how Crusoe designs, provisions, and operates its network at hyperscale
Hyperscale Data Center Architecture: Own end-to-end network architecture for Crusoe's AI data centers, including spine-leaf fabrics, out-of-band management, RDMA (RoCEv2/InfiniBand), and inter-campus WAN design
SDN Control Plane Design: Design and evolve SDN control plane architectures for programmable underlay and overlay networking across multi-vendor hardware environments
Kubernetes Networking: Define CNI selection, network policies, multi-cluster service mesh, and BGP peering architecture across Crusoe's Managed Kubernetes platform
Intent-Based Networking: Architect IBN frameworks that translate high-level business and operational goals into validated, auto-generated device configurations
Declarative Networking and GitOps: Establish infrastructure-as-code practices, GitOps-driven network provisioning, and continuous validation pipelines for network state
Network Source of Truth: Build and own Crusoe's SoT strategy, defining authoritative data models (IPAM, DCIM, CMDB) and ensuring all devices, links, and policies are version-controlled and consistently sourced
Automation Workflows: Design day-0/1/2 automation using tools like Ansible, Nornir, or Terraform, driven by the network source of truth
Observability and Telemetry: Define streaming telemetry architecture (gNMI/gRPC), intent verification, and closed-loop remediation pipelines
Standards and Cross-Functional Leadership: Establish engineering standards and reference architectures, lead architecture reviews, author design documents, and present proposals to senior leadership
Team Mentorship: Mentor senior and staff network engineers, growing the technical depth and breadth of the broader network engineering team
