Member of Technical Staff - Mid-training

Palo Alto, CA

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 understand the universe and help expand humanity’s knowledge and capabilities. We work across the full Super Intelligence stack: compute (Colossus supercomputers), models (Grok), and applications (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.

RESPONSIBILITIES:

  • Scale synthetic coding data to trillions of tokens with large-scale docker verification.
  • Distill the intelligence of flagship models into flash models through synthetic data generation.
  • Optimize mid-training data mixtures to boost the ceiling for RL.
  • Engineer long-context data recipes.
  • Develop robust and diverse evaluation for mid-training checkpoints.

BASIC QUALIFICATIONS:

  • Expertise in ML and large model scaling, with familiarity across all kinds of scaling laws.
  • Strong ability to design ML experiments.
  • Familiarity with state-of-the-art techniques for curating AI training data for text, image, audio, and video modalities.
  • Strong engineering abilities in Spark, Ray, and other frameworks for large-scale data processing.

COMPENSATION AND BENEFITS:

$180,000 - $440,000 USD

Base salary is just one part of our total rewards package at SpaceXAI, 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.
