Principal Network Architect

Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster.

We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI.

We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services.

If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe.

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.

• Experience at a hyperscaler, AI cloud provider, HPC center, or large-scale co-location operator.

• Hands-on experience with SONiC OS, P4 programmable data planes, SRv6, or silicon-level knowledge of Broadcom Tomahawk/Trident.

• Open source contributions to networking projects such as SONiC, NetBox, FRR, or Cilium.

• Familiarity with formal network verification tools like Batfish or Minesweeper, or eBPF-based networking and observability.

• Relevant certifications including CCIE (DC/SP), JNCIE, or vendor-specific SDN/cloud certifications.
