You will evaluate and annotate AI model outputs by providing rigorous mathematical solutions and identifying errors in reasoning or numerical computations. You will also collaborate with technical teams to improve annotation workflows and train new tasks to enhance the performance of Grok models.
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.
In this role, you will help enhance Grok by providing high-quality data annotations, labels, and inputs focused on applied mathematics. You will draw on your expertise in areas such as numerical analysis and scientific computing, ordinary and partial differential equations, probability and applied statistics, computational linear algebra, and mathematical physics or mathematical biology to evaluate model outputs, identify modeling errors or numerical issues, and produce clear, rigorous solutions and explanations. This role requires strong mathematical writing skills, attention to precision, and the ability to maintain logical consistency throughout complex mathematical arguments. Your work will help train Grok to distinguish flawed or inadequately justified approaches from solutions that are mathematically sound, accurately modeled, and practically applicable.
