Site Reliability Engineer — HPC & Automation; Silicon Engineering

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.

At SpaceX we’re leveraging our experience in building rockets and spacecraft to deploy Starlink, the world’s most advanced broadband internet system. Starlink is the world’s largest satellite constellation and is providing fast, reliable internet to millions of users worldwide. We design, build, test, and operate all parts of the system – thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together.

We’ve only begun to scratch the surface of Starlink’s potential global impact and are looking for best‑in‑class engineers to help maximize Starlink’s utility for communities and businesses around the globe.

We are seeking a motivated, proactive, and intellectually curious engineer who will work alongside world‑class cross‑disciplinary teams (systems, firmware, architecture, design, validation, product engineering, ASIC implementation). As a Site Reliability Engineer on the Silicon Engineering team you will get the opportunity to design, operate, scale, and automate the high performance computing infrastructure we use to develop the chips powering the world's largest satellite constellation and a global internet service.

This position will have a meaningful impact on Starlink silicon by enabling faster design-iterations, simulations, and regression turnaround times that gate how fast our chip teams can ship.

• Deploy, upgrade, operate, maintain, and scale our suite of clusters and services
• Collaborate with engineers to develop automated, full turnkey solutions for silicon simulation workflows to speed up project timelines
• Manage our underlying infrastructure as code and use modern observability tools to provide a complete picture of cluster and infrastructure health
• Operate the continuous integration pipeline, build and release systems, and version control across the environment
• Identify and eliminate performance bottlenecks using measurement and creative engineering

• Bachelor’s degree in computer science, information systems, or an engineering discipline; OR 2+ years of professional experience in system administration, high performance computing, or site reliability engineering
• 1+ years of development experience with Bash, Python, and/or other programming languages
• 1+ years of experience with Linux operating systems PREFERRED SKILLS AND EXPERIENCE
  • Familiarity with containerization technologies (i.e. Docker, Kubernetes)
  • Knowledge in computer system concepts (computer architecture, computer organization, operating systems and concurrency)
  • Experience with databases and data modeling (e.g.,MySQL,PostgreSQL, SQLite)
  • Networking knowledge of TCP/IP
  • Experience with high performance computing and workload managers (e.g., Slurm, LSF)
  • Experience with Terraform, Ansible, Puppet, or similar automation frameworks
  • Experience building monitoring and alerting as code (e.g., Grafana, Prometheus, custom exporters)
  • Experience with CI/CD automation at scale (e.g., Jenkins, Bamboo, build systems)
  • Experience with infrastructure as code (IaC) tools for managing fleets of servers
  • Experience with using & building REST API clients/servers
  • Experience with enterprise/networked storage automation (e.g., Net App ONTAP REST API/CLI, NFS)
  • Experience with ASIC design flows and tools (e.g., Cadence, Synopsys, Ansys, Keysight, Siemens)
  • Strong desire to find performance bottlenecks and performance improvement techniques
  • Excellent communication skills with the ability to communicate with customers, peers, management, etc. in both formal and informal situations
  • Ability to quickly learn new tools and frameworks
  • Interest in or experience with AI/LLM-assisted tooling (e.g., Grok, Claude Code)
  ADDITIONAL REQUIREMENTS
  • Ability to work extended hours and weekends as needed to meet critical milestones
