In the posting’s own words

We're looking for a Research Scientist who has done hands-on research on large models (pretraining, fine-tuning, RL, evals, or agents scaffolds) and wants to focus on measuring and understanding recursive-self-improvement. You know what the model-development loop looks like from the inside: which signals matter and where the real bottlenecks are. On this team you'll use that judgment to decide what's worth measuring, design the evaluations and models that measure it, and interpret what the results mean for how fast this is moving.

What it asks for · 7

  • Have done hands-on research on large language models: pretraining, fine-tuning, RL, evals, or agent systems
  • Have strong quantitative instincts, are comfortable with quantitative modeling and reasoning
  • Have experience in forecasting, may have published AI forecasting scenarios
  • Can design an evaluation from a vague question and defend the methodology
  • Write clearly and calibrate: state confidence, name what would change your conclusion
  • Are motivated by impact: comfortable with work whose output is graded assessments and system-card sections more often than papers
  • Care about AI safety and think carefully about where rapid capability growth leads

Also a plus

  • Trained or RL'd frontier models hands-on
  • Experience with scaling laws, capability forecasting, or emergent-capability studies
  • A physics, applied-math, or similarly quantitative background that moved into ML
  • Written a system card section, capability report, or methodology document that others cite
  • Experience supervising and correcting AI-written code

What the job covers

  • Identify the signals that track AI R&D acceleration and design the evaluations that measure them
  • Build quantitative models of capability growth and self-improvement dynamics, grounded in evaluation and telemetry data
  • Run experiments and evals to test hypotheses about automation and capability
  • Make opinionated research bets and own the outcome
  • Write graded assessments of what our measurements show, for internal decision-makers and public reporting
  • Collaborate with pretraining, RL, economic research, and policy teams

How this page was made

An automated read of a public job posting, fetched August 25, 2026 and last changed by Anthropic on August 21, 2026. Every list above is pulled from the posting’s own sentences — nothing rewritten, nothing added, no judgment about the role or the company. Counts and seniority are read off the text by rule, so they can be wrong where the posting is unusual. The original is the only thing that binds. Openings close without warning; check the source before spending an evening on it.
