About the 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.

We're looking for individuals who have built exceptional advertising products and systems at a massive scale across bidding, auction, marketplace, ranking, prediction, and product. We're bringing SpaceXSI's technology stack to Ads Platform and using it to transform our advertising stack.

Responsibilities

  • Leverage the latest Grok models to power all stages of our advertising stack, from candidate selection to ranking, auction, campaign optimization, creative generation, and advertiser experience
  • Own and operate systems and products, driving the majority of revenue

Basic Qualifications

  • 5+ years of industry experience working on large-scale, high-throughput AI-powered advertising products

Preferred Skills and Experience

  • Experience in writing CUDA kernels
  • Skilled in one or more DL software frameworks such as JAX or PyTorch
  • Knowledge of data infrastructure like Kafka, Clickhouse, and Spark

Compensation and Benefits

$180,000 - $330,000 USD
