About this role
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.
AI TUTOR, PORTUGUESE - TEMPORARY
In this role, you will help train and refine Grok's voice and language capabilities in Portuguese. Your expertise will directly shape how Grok speaks and understands Portuguese, from pronunciation and natural phrasing to cultural nuance. You will see your work show up in a product used by people around the world.
