Job summary

SpaceXAI in Dublin is seeking a hands-on Network Engineer to design, deploy, and operate production datacenter and campus networks at scale. You will own routing and switching standards (BGP and at least one IGP such as OSPF/IS-IS), qualify platforms, and push changes safely while maintaining high availability as we scale.

You will collaborate with compute, facilities, and software teams, travel to build sites as needed, and participate in on‑call rotations.

Qualifications

• Several years designing and operating production networks in a datacenter, ISP, cloud, or large enterprise environment.
• Solid hands‑on experience with BGP and at least one interior routing protocol.
• Strong knowledge of TCP/IP, VLANs, EVPN/VXLAN, and optics / high‑speed Ethernet.

Responsibilities

• Design, deploy, and operate production datacenter and campus/core networks at scale
• Own routing and switching configuration standards (BGP and at least one IGP such as OSPF or IS-IS), including change design, peer reviews, and execution
• Qualify new network platforms, optics, and topologies; contribute to architecture and capacity planning
• Build and improve monitoring, alerting, and operational documentation so issues are caught and fixed quickly
• Troubleshoot Layer 2/Layer 3 incidents end to end — from link flaps and optics through routing and traffic engineering — and drive root cause and lasting fixes
• Automate repetitive network tasks with Python, Ansible, or similar tooling where it reduces toil
• Partner with compute, facilities, and software teams during cluster build‑outs and maintenance windows
• Support high-performance / supercompute network environments (Ethernet AI/HPC fabrics, RoCE/RDMA‑capable designs) as part of the broader network estate — deep specialist RoCE/NCCL ownership is a plus, not the bar for this seat
