Site Reliability Engineer (High Performance Computing)

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.SITE RELIABILITY ENGINEER (HIGH PERFORMANCE COMPUTING)SpaceX HPC is a shared compute platform used across the company — vehicle and structures simulation, machine learning, AI inference, and more. We support every program at SpaceX to design and operate the worlds most advanced rockets and satellites. This role exists to put a real Site Reliability Engineer operating model on these capabilities and accelerating the world class engineering at SpaceX: toil reduction, automation, observability, and a sustainable incident process.We are looking for a Site Reliability Engineer who wants to own everything from Linux machines and our Infrastructure as Code, storage, and user facing applications – the whole ecosystem as a product, not as a ticket queue. You do not need a prior HPC title. You do need production instincts — you have operated real infrastructure, you write code to delete toil, and you care about whether users can actually get work done, not just whether nodes ping. You’ll work alongside HPC systems engineers who design and commission clusters to help make them more reliable and provide world class services for world class engineers.Aerospace experience is not required. We value engineers who treat teammates with fairness and respect, who are self-critical, and who will take ownership of hard production problems.RESPONSIBILITIES:Participate in the team's on-call rotation; practice sustainable incident response and blameless postmortemsManage node lifecycle with infrastructure as code: OS images, firmware, configuration management, kernel and driver stackBuild observability for both HPC administrators and end users — cluster, node, and storage health for operators, and job/workflow-level signal for the people running work on the platformReduce toil with automation; split time between operating production systems and writing the software that makes that work smallerSustainably manage resources, including compute and storageLead capacity planning with users across the company: understand what they will need next, and turn that into a concrete picture of tomorrow's compute and storageCollaborate with HPC systems engineers and with engineers across all disciplines across the company on operable, maintainable infrastructureBASIC QUALIFICATIONS:Bachelor's degree in computer science, engineering, math, or a scientific discipline; OR 2+ years of professional experience operating production infrastructure in lieu of a degree2+ years of experience with Linux operating systems in production2+ years of experience operating production infrastructure (servers, services, or networks), including monitoring, debugging, and repairing what you ownPREFERRED SKILLS AND EXPERIENCE:2+ years of professional experience in SRE, DevOps, or production infrastructure engineeringExperience with monitoring and alerting (Prometheus, Grafana, Nagios, or similar)Experience deploying and maintaining configuration management or infrastructure as code (Ansible, Puppet, Terraform, or similar)Experience writing scripts/code (eg. Python or similar languages) to automate common tasksExperience with containers (Docker, Podman, Singularity/Apptainer)Experience with Kubernetes administration for on-premise deploymentExperience with distributed or high-performance storage (VAST or similar), including capacity, performance, and lifecycle managementFamiliarity with HPC clusters, schedulers (Slurm, PBS, LSF), or GPU compute — not required; we will teach thisFamiliarity with scientific computing (CFD, FEA) and/or ML training workloads (PyTorch, TensorFlow, CUDA) and/or AI inference workloadsGood understanding of version control, testing, continuous integration, build, deployment and monitoringAbility to communicate clearly with users, peers, and vendors in both incident and design settingsComfortable working with mission-critical and sensitive systems, with a sense of urgency appropriate to the responsibilitiesEligibility for access to classified material up to TS/SCI with polygraphADDITIONAL REQUIREMENTS:Position is based in Hawthorne, CA and is primarily on-siteMust be able to participate in an on-call rotationMust be willing to work extended hours and weekends as needed for incidents, cluster bring-up, and time-critical failuresCOMPENSATION AND BENEFITS: Pay Range: Level 1: $125,000.00 - $160,000.00Level 2: $145,000.00 - $195,000.00Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.Base salary is just one part of your total rewards package at SpaceX.
