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.\nSOFTWARE ENGINEER, OBSERVABILITY (SUPERCOMPUTE)\nThe Supercompute Observability Software team owns keeping our supercompute centers running reliably at the unprecedented scale required for frontier AI training and inference by building software systems and platforms to automatically predict, monitor, and rapidly respond to changing operational conditions and incidents. Our clusters are large, heterogeneous, and always on - the team makes them observable and keeps them running: we build the infrastructure that lets engineers and technicians expedite and automate their day to day, speeding node remediation and increasing overall GPU uptime. The team partners closely with datacenter operations, AI research, and facility infrastructure teams to deliver high-impact tools that turn raw operational data into clear insight and action, ensuring true site-wide reliability and automated operation.\nRESPONSIBILITIES:\nDesign, build, and operate multi-service production systems (UI, APIs, data pipelines, auth, and on-call) to enable reliability, uptime monitoring, predictive alerting, upgrade/change/risk management, and site-wide impact assessments\nDesign, build, and operate predictive and analytical tools that inform better design and operations of future and current supercompute centers\nDevelop frontend visualizations, interactive dashboards, and UI components that present processed data in clear, real-time views for operators, capacity planners, and engineering stakeholders\nWork day to day with your users, in person, to rapidly incorporate feedback and process improvements that improve GPU uptime\nBASIC QUALIFICATIONS:\nProgramming experience in Python, Rust, C++, or Java\nExperience working with Postgres, MySQL, MongoDB, DynamoDB, or other database management systems\nPREFERRED SKILLS AND EXPERIENCE:\nSuper Intelligence (SI) driven software development practices\nProven ownership of correctness-sensitive systems - state machines, workflows, or operational data where inaccurate state has real-world impact\nExperience collaborating with cross-functional teams\nBachelor's degree in computer science, engineering, math, or a STEM discipline and 3+ years of professional software development experience; OR 5+ years of professional software development experience in lieu of a degree\nExperience building or operating large-scale observability, telemetry, or real-time analytics systems\nExperience with time-series or analytical databases (Prometheus/VictoriaMetrics, ClickHouse, InfluxDB) and streaming or high-volume telemetry pipelines\nExperience building observability dashboards and alerting with Grafana, New Relic, Splunk, or similar\nFrontend experience with React, Angular, or a comparable JavaScript framework, building intuitive UIs for critical operations\nExperience operating services on cloud or on-prem infrastructure with Docker/Kubernetes in production and automated CI/CD deploys (ArgoCD, GitHub Actions, etc.)\nExperience with HPC or supercomputing environments (schedulers such as Slurm, GPU/accelerator telemetry, high-speed fabrics, or parallel filesystems)\nExperience integrating with industrial/OT data sources (SCADA platforms such as Ignition, tag historians, Modbus/OPC-UA) or power/cooling infrastructure telemetry\nADDITIONAL REQUIREMENTS:\nAbility to work extended hours or weekends as needed for mission-critical deadlines\nAbility to work full-time on-site at a SpaceX office\nAbility to travel to supercompute centers (up to 25-50% based on need)\nSpaceXSI is an equal opportunity employer.
