Generative AI chatbot leveraging real-time data
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.
The X Search team is responsible for building and operating the core search engine that powers discovery on X. We own the full end-to-end search stack — from real-time retrieval and indexing to ranking and the end-user search experience.
Our goal is to create the most relevant, fast, and intelligent search experience on the internet by combining state-of-the-art information retrieval systems with Grok’s reasoning capabilities.
$180,000 - $330,000 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.

xAI builds Grok, a generative AI chatbot with a Hitchhiker's Guide-inspired persona that uses real-time data from X to produce current, culturally aware responses. Grok is accessible to premium subscribers on X, via a standalone website, mobile apps, and through an API for developers. The company also develops large-scale AI infrastructure, such as the Colossus supercomputer, to train and run its models. Its goal is to pursue truth-seeking AGI research and grow a capital-intensive platform that could support a major public offering in the future.
