Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.\nSpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.\nABOUT THE ROLE:\nSpaceXSI is building and operating large-scale networks that underpin training and inference infrastructure, including high-performance / supercompute fabrics that connect GPU clusters, plus the core, edge, and datacenter networks that keep that infrastructure reachable and reliable.\nWe need a Network Engineer who is strong on fundamentals and comfortable owning production network design, deployment, and operations end to end. 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.\nTravel to Memphis (and other build sites) may be required for capacity build-outs. You will participate in a team on-call rotation.\nRESPONSIBILITIES:\nDesign, deploy, and operate production datacenter and campus/core networks at scale\nOwn routing and switching configuration standards (BGP and at least one IGP such as OSPF or IS-IS), including change design, peer reviews, and execution\nQualify new network platforms, optics, and topologies; contribute to architecture and capacity planning\n Build and improve monitoring, alerting, and operational documentation so issues are caught and fixed quickly\nTroubleshoot 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\nAutomate repetitive network tasks with Python, Ansible, or similar tooling where it reduces toil\n Partner with compute, facilities, and software teams during cluster build-outs and maintenance windows\n 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\nBASIC QUALIFICATIONS:\n Several years designing and/or operating production networks in a datacenter, ISP, cloud, or large enterprise environment\n Solid hands-on experience with BGP and at least one interior routing protocol\nWorking knowledge of TCP/IP, VLANs, EVPN/VXLAN or equivalent datacenter overlays, and optics / high-speed Ethernet\nExperience troubleshooting live production network incidents and participating in on-call\nStrong written and verbal communication; clear change docs and incident notes\nBachelor’s degree or higher in Computer Science, Computer Engineering, Electrical Engineering, or a closely related field directly relevant to the position’s duties, or its equivalent.\nPREFERRED SKILLS AND EXPERIENCE:\nExperience with modern datacenter vendors (e.g. Arista, Cisco, Juniper, Nvidia/Mellanox)\nFamiliarity with high-performance or supercompute networking (RoCEv2, congestion control, GPU cluster fabrics) - useful context for our environment, not a hard filter\n Network automation (Python, Ansible, Terraform, or similar) used in production\nExperience with EVPN, leaf-spine, and large-scale Ethernet fabrics\n Prior work supporting rapid datacenter or cluster capacity build-outs\nADDITIONAL REQUIREMENTS:\nWilling to work onsite in Palo Alto\nCOMPENSATION AND BENEFITS:\n$150,000 - $250,000 USD\nBase salary is just one part of our total rewards package at SpaceXSI, 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.\nSpaceXSI is an equal opportunity employer.
