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 making life multiplanetary and expanding consciousness to the stars.

SpaceXSI 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.

ABOUT THE ROLE:

We’re looking for exceptional storage & database engineers who want to join us on a new project to deeply integrate SpaceXSI's advanced AI infrastructure into a platform used by around 600 million users every month. We’re building a new storage tier that powers training, inference, recommendations, and real-time data extraction.

We build and operate:

  • An exabyte-scale S3-compatible object store
  • A multi-tenant transactional key/value store that serves 100s of millions requests per second
  • A caching tier that serves billions of requests per second
  • A scalable vector database that powers our recommendation systems
  • A few other specialized databases serving hundreds of millions requests per second

RESPONSIBILITIES:

  • Design, build, and launch to production new features and improvements aimed at unifying common components across the storage systems
  • Dive into performance issues and work with customers and deliver solutions to cater to customers’ latency, availability and data durability requirements.
  • Lead and drive incident responses and recovery with your peers. Review and contribute to incident postmortems and hold a high bar for the same.
  • Work in a collaborative environment and uplevel your peers by doing mentoring, code and design reviews.
  • Be open to develop new skills and learn on the job as we navigate new technology spaces.
  • Ground your decisions with data and reasoning and adapt to new information to make informed choices.

BASIC QUALIFICATIONS:

  • Have at least 7 years of experience in software development, plus 2+ years building storage systems or databases.
  • Obsessed with reliability, performance, and quality
  • Proficient in high performance C++, Rust, or JVM-based languages
  • Expertise in building, running, and operating scalable and resilient distributed systems

COMPENSATION AND BENEFITS:

$180,000 - $440,000 USD

Base 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.
