SpaceXAI aims to develop AI systems that accurately understand the universe and support humanity's pursuit of knowledge. The organisation operates with a flat structure, emphasising hands-on contributions and strong communication skills.

### About the Role

SpaceXAI is building large-scale networks for training and inference infrastructure, including high-performance computing fabrics and core, edge, and datacentre networks. We seek a Network Engineer experienced in production network design, deployment, and operations.

This hands-on role involves designing and building networks, qualifying platforms, and ensuring high availability and performance. Travel to build sites, such as Memphis, may be required, and participation in on-call rotations is expected.

### Responsibilities

- Design, deploy, and operate production datacentre and campus/core networks at scale

- Develop and maintain routing and switching configuration standards, including BGP and an interior gateway protocol such as OSPF or IS-IS

- Qualify new network platforms, optics, and topologies, contributing to architecture and capacity planning

- Improve monitoring, alerting, and operational documentation to quickly identify and resolve issues

- Troubleshoot Layer 2/Layer 3 incidents end-to-end, driving root cause analysis and lasting fixes

- Automate repetitive network tasks using Python, Ansible, or similar tooling

- Collaborate with compute, facilities, and software teams during cluster build-outs and maintenance windows

- Support high-performance computing network environments, including Ethernet AI/HPC fabrics and RoCE/RDMA-capable designs

### Basic Qualifications

- Several years of experience designing and operating production networks in datacentre, ISP, cloud, or large enterprise environments

- Hands-on experience with BGP and at least one interior routing protocol

- Working knowledge of TCP/IP, VLANs, EVPN/VXLAN, and optics/high-speed Ethernet

- Experience troubleshooting live production network incidents and participating in on-call rotations

- Strong written and verbal communication skills

### Preferred Skills and Experience

- Experience with modern datacentre vendors such as Arista, Cisco, Juniper, or Nvidia/Mellanox

- Familiarity with high-performance or supercompute networking, including RoCEv2 and congestion control

- Network automation experience with Python, Ansible, Terraform, or similar tooling

- Experience with EVPN, leaf-spine, and large-scale Ethernet fabrics

- Prior work supporting rapid datacentre or cluster capacity build-outs

### Additional Requirements

- Willingness to work onsite in Dublin

### Compensation and Benefits

The salary range is $100,000 - $150,000 base. The total rewards package includes equity, comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short and long-term disability insurance, life insurance, and various discounts and perks.
