This is a hands-on engineering seat — not a NOC technician role and not a network-software (telemetry/ZTP platform) SWE role. You will design and build networks, qualify platforms, ship changes safely, and keep availability and performance high as we scale.</p> <p>Travel to Memphis (and other build sites) may be required for capacity build-outs. You will participate in a team on-call rotation.</p> <p><strong>Responsibilities</strong></p> <ul> <li>Design, deploy, and operate production datacenter and campus/core networks at scale</li> <li>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</li> <li>Qualify new network platforms, optics, and topologies; contribute to architecture and capacity planning</li> <li> Build and improve monitoring, alerting, and operational documentation so issues are caught and fixed quickly</li> <li> 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</li> <li> Automate repetitive network tasks with Python, Ansible, or similar tooling where it reduces toil</li> <li> Partner with compute, facilities, and software teams during cluster build-outs and maintenance windows</li> <li> 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</li> </ul> <h3 data-pm-slice="1 1 []"> </h3> <p><strong>Basic Qualifications</strong></p> <ul> <li> Several years designing and/or operating production networks in a datacenter, ISP, cloud, or large enterprise environment</li> <li> Solid hands-on experience with BGP and at least one interior routing protocol</li> <li>Working knowledge of TCP/IP, VLANs, EVPN/VXLAN or equivalent datacenter overlays, and optics / high-speed Ethernet</li> <li> Experience troubleshooting live production network incidents and participating in on-call</li> <li>Strong written and verbal communication; clear change docs and incident notes</li> </ul> <h3 data-pm-slice="1 1 []"> </h3> <p><strong>Preferred Skills and Experience</strong></p> <ul> <li>Experience with modern datacenter vendors (e.g. Arista, Cisco, Juniper, Nvidia/Mellanox)</li> <li> Familiarity with high-performance or supercompute networking (RoCEv2, congestion control, GPU cluster fabrics) — useful context for our environment, not a hard filter</li> <li> Network automation (Python, Ansible, Terraform, or similar) used in production</li> <li> Experience with EVPN, leaf-spine, and large-scale Ethernet fabrics</li> <li> Prior work supporting rapid datacenter or cluster capacity build-outs</li> </ul> <h3 data-pm-slice="1 1 []"> </h3> <p><strong>Additional Requirements</strong></p> <ul> <li> Willing to work onsite in Dublin</li> </ul> <h3><strong>COMPENSATION AND BENEFITS:</strong></h3> <p>$100,000 - $150,000 Base </p> <p>Base salary is just one part of our total rewards package at SpaceXAI, which also includes equity, comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, short & long-term disability insurance, life insurance, and various other discounts and perks.</p> <h3 data-pm-slice="1 1 []"><br><br><br></h3><div class="content-conclusion"><p><em>SpaceXAI is an equal opportunity employer.
