About the role

  • Conducting experiments to figure out efficient ways to train a large language model on traces of interactions with various environments.
  • Exploring methods of guided generation and search in the trajectory space
  • Coming up with ways to mine relevant data at web scale and figuring out efficient ways to use this data in model post-training.
  • Conducting experiments with different reinforcement learning configurations in verifiable domains
  • Exploring methods to train AI agents on tasks with non-verifiable reward signals

Requirements

  • A profound understanding of theoretical foundations of machine learning and reinforcement learning.
  • Deep expertise in modern deep learning for language processing and generation
  • Substantial experience with training large models on multiple computational nodes
  • Strong software engineering skills (we mostly use python)
  • Deep experience with modern deep learning frameworks (we use jax)
  • Strong communication and leadership abilities
  • Experience designing, executing, and analyzing machine learning experiments with proper statistical rigor
  • Ability to formulate research questions, design experiments to test hypotheses, and draw meaningful conclusions from results
  • Ability to document research findings clearly and contribute to technical publications or report
  • Experience with deep reinforcement learning for LLMs, including techniques such as reward modeling, DPO, PPO etc.
  • Familiarity with important ideas in LLM space, such as MHA, RoPE, ZeRO/FSDP, Flash Attention, quantization
  • Bachelor’s degree in Computer Science, Artificial Intelligence, Data Science, or a related field Master’s or PhD preferred.
  • Track record of building and delivering products (not necessarily ML-related) in a dynamic startup-like environment
  • Experience in engineering complex systems, such as large distributed data processing systems or high-load web services
  • Open-source projects that showcase your engineering prowess
  • Excellent command of the English language, alongside superior writing, articulation, and communication skills.
  • Proficiency in contemporary software engineering approaches, including CI/CD, version control and unit testing.
Benefits
  • Competitive salary and comprehensive benefits package.
  • Opportunities for professional growth within Nebius.
  • Flexible working arrangements.
  • A dynamic and collaborative work environment that values initiative and innovation.
