Staff Research Engineer, Multi-Agent ScalingNew$500K

The opportunity

Large teams of agents are starting to solve problems no single agent can, from rewriting major codebases to formalizing landmark mathematics. Our team studies how these teams scale: what happens to performance, cost and coordination as the number of agents, the compute budget…

What you'll do

  • Design, run and interpret large-scale experiments on agent teams, reasoning: rigorously about what the data does and doesn't show

  • Investigate how performance and efficiency change as team size, compute and: task horizon grow, and find the bottlenecks that limit them

  • Build and scale the systems that run very large agent teams reliably, and: debug the failures that only appear at scale

  • Design evaluations for long-horizon problems, and keep their results trustworthy

  • Build the tooling and metrics that let researchers see what a large agent team is doing and why

  • Partner with research teams across Anthropic so they can run their own: experiments on the platform, and communicate findings clearly

What they're looking for

  • Have significant software engineering, ML or research engineering experience
  • Have owned something substantial end to end, such as a large system, an: evaluation or benchmark, an agent product, or a research project
  • Genuinely enjoy both research and engineering work
  • Think quantitatively about complex systems, and think twice before trusting a number
