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:\nThis team owns 100% GPU uptime, end to end, 24/7, across both compute and facility. It owns incident response and the engineering behind it, holds central control authority from the customer back to the facility, runs day-to-day sustainment of live datahalls, and leads deployment engineering for new datahall bring-up. The team will also build the automation for continuous response improvement. The team is expected to have system level knowledge about the whole datacenter site, end to end. The team engineers solutions to enable GPU uptime, working directly with technicians in the datahalls and field to execute the team’s engineering planning.\nRESPONSIBILITIES:\nOwn monitoring architecture, alerting, signal quality, and automation of monitoring across GPU and host telemetry (DCGM, Prometheus/Grafana) and facility telemetry (BMS, EPMS, DCIM, SCADA, CDU / direct liquid cooling).\nOwn compute hardware change incorporation - physical, firmware, software.\nBe part of 24/7 iincident response, mitigation, and control authority - end to end - from customer impact back to the facility.\nOwn day-to-day site sustainment operations, including resolving issues impacting rack-level compute and facility infrastructure.\nDisposition daily issues across both Site Operations (rack compute) and Facility Operations (power and cooling).\nLead acceptance and deployment testing campaigns to bring new data halls fully online.\nDevelop production automation for new datahall bring-up, automation behind alerting and automated incident response.\nDevelop and maintain standard operating procedures and planning for facility and site technicians. Includes change / upgrade incorporation planning on both rack level and facility.\nOwn and document the live, changing state of datahall operation as new halls come online.\nEnable Site Operations and Facility Operations technicians to do their day to day jobs more efficiently and safely to increase GPU uptime.\nCreate predictive and responsive automation to alerts and incidents to enable your response to be faster and more impactful.\nLead cross-functional reliability projects spanning compute, network (InfiniBand/RoCE), storage, and facility signal boundaries, including grey failures that cross those boundaries (e.g., NVLink flapping, thermal throttling, power sequencing).\nTruly root cause systemic and design failure classes across hardware and integrated facility and operations systems: turn fleet data (MTBF/AFR, repeat-RMA trends) into proactive alerting, standard responses, vendor RCA inputs, and supplier corrective actions.\nBASIC QUALIFICATIONS:\nBachelor's degree in Mechanical, Electrical, or Computer Engineering or a related scientific discipline and 2+ years of experience in data center, critical facilities, power plant, or large-scale compute operations; or 6+ years of equivalent experience in those environments.\nPREFERRED SKILLS AND EXPERIENCE:\nHands-on experience with at least one of: Prometheus/Grafana, NVIDIA DCGM, or industrial telemetry and controls (SCADA, BMS/BAS, EPMS, DCIM, PLCs, Modbus/BACnet).\nExperience in datacenter site reliability, systems engineering, plant operations, or large-scale production operations.\nExperience running acceptance test campaigns for integrated products.\nExperience in AI/ML infrastructure or supercomputing environments: GB200/NVL72 or H100/H200-class GPU fleets, NCCL, InfiniBand/RoCE, Slurm or Kubernetes.\nFleet firmware and BMC management (Redfish, IPMI), including firmware release validation and staged rollouts.\nFamiliarity with data center hardware and plant signals (servers, GPUs, networking, power, cooling) in addition to software telemetry.\nProven large-scale incident command experience and calm technical leadership on a bridge, whether from an SRE/NOC bridge or a plant control room.\nExperience writing and operating playbooks, runbooks, or standard operating procedures, methods of procedure, emergency operations procedures.\nProficiency in scripting (Python, Bash) for automation and analysis, plus general experience in at least one systems language (C, C++, Java, Go, Rust, or similar).\nAbility to work collaboratively with cross-functional, cross-country, multi-disciplinary teams.\nSpaceXSI is an equal opportunity employer.
