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:\nThe Observability team builds and operates the core infrastructure that enables engineers to monitor, debug, and optimize the performance and reliability of their systems. We handle telemetry at massive scale - billions of time series and petabytes of logs - with strict performance and availability requirements.\nYou will be part of the small, high-impact team responsible for building and maintaining SpaceXSI's observability platform. You’ll own critical systems that power metrics, logs, tracing, and alerting enabling engineering teams to operate services at scale, identify issues before they impact users, and drive systemic reliability improvements.\nRESPONSIBILITIES:\nDesign and implement scalable observability infrastructure for metrics, logging, and tracing.\nBuild high-performance telemetry pipelines that handle massive ingestion volumes.\nDevelop APIs, query engines, and UIs that allow engineers to get real-time insights into their services.\nDefine and enforce best practices for instrumentation, alerting, and reliability across the company.\nPartner with infrastructure and product teams to deeply integrate observability into our internal platforms.\nOwn the reliability, scalability, and performance of the observability stack end-to-end.\nBASIC QUALIFICATIONS:\nProduction-level proficiency in Go, Rust, Scala, or a similar languages\nDeep understanding of distributed systems and telemetry architecture.\nExperience building and operating infrastructure at scale.\nFamiliarity with observability stacks such as Prometheus, Grafana, OpenTelemetry, VictoriaMetrics, or ClickHouse.\nExperience with Kafka, Redis, or large-scale time series databases.\nExperience operating observability pipelines in Kubernetes or similar orchestration environments.\nCOMPENSATION AND BENEFITS:\n$180,000 - $440,000 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.
