Research Scientist, Ai, Formal and Informal Reasoning

Meta Meta · Big Tech · Paris, France

Research Scientist at Meta's FAIR organization focusing on advancing LLM reasoning capabilities through reinforcement learning, synthetic data generation, and agentic techniques, with a specialization in formal and informal mathematical reasoning. The role involves leading research, contributing to experiments, publications, and open-sourcing efforts.

What you'd actually do

  1. Lead, collaborate, and execute on research that pushes forward the state of the art in reasoning research, with an initial focus on formal and informal mathematical reasoning
  2. Work towards long-term high-stakes research goals, while identifying intermediate milestones
  3. Directly contribute to experiments, including designing experimental details, implement reusable code, running evaluations, and organizing results
  4. Contribute to publications and open-sourcing efforts
  5. Mentor other team members.
