Job Description

As a Member of Technical Staff in the pretraining evals team, you will play a key role in helping us make modelling decisions based on experimental outcomes for our large language models (LLMs). Your primary focus will be on developing better ways to measure base model progress. This can include implementing new/better evaluations for base model capabilities, finding ways to reduce noise in our current model evaluations, or developing evaluation benchmarks that measure model progress at all model scales, among other directions.

Job Responsibility

  • Deeply understand each individual evaluation task in our base model evaluation suite, have a clear idea of what each task measures and know their strengths and limitations
  • Suggest and implement improvements to our base model evaluation suite, whether by adding new tasks to measure unmeasured model capabilities or removing redundant or low-signal tasks
  • Improve the statistical understanding of our evals and improve the signal-to-noise ratio of our evaluation suite

Requirements

  • Familiarity with base model evaluations and how they differ from post-trained models
  • Strong statistical skills and experience evaluating scientific experiments related to data collection and model performance
  • Ability to convey statistical information effectively to a broad audience using visualizations and easy-to-understand numbers
  • Extremely strong software engineering skills
  • Proficiency in programming languages such as Python and ML frameworks (e.g., PyTorch, TensorFlow, JAX)
  • Excellent communication skills to collaborate effectively with cross-functional teams and present findings
  • One or more papers at top-tier venues (such as NeurIPS, ICML, ICLR, AIStats, MLSys, JMLR, AAAI, Nature, COLING, ACL, EMNLP)

What we offer

  • An open and inclusive culture and work environment
  • Work closely with a team on the cutting edge of AI research
  • Weekly lunch stipend, in-office lunches & snacks
  • Full health and dental benefits, including a separate budget to take care of your mental health
  • 100% Parental Leave top-up for up to 6 months
  • Personal enrichment benefits towards arts and culture, fitness and well-being, quality time, and workspace improvement
  • Remote-flexible, offices in Toronto, New York, San Francisco, London and Paris, as well as a co-working stipend
  • 6 weeks of vacation (30 working days!)
