Job summary

Anthropic is seeking a Staff Research Engineer for multi-agent scaling to design and run large experiments, build scalable systems for very large teams, and interpret results to advance research and practice. This role sits at the intersection of research and engineering and requires hands-on implementation and rigorous analysis.

The team values quantitative thinking, strong communication, and a bias for impact.

Qualifications

• Significant software engineering, ML or research engineering experience.
• 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.
• Can work from a vague question rather than a spec.
• Are results-oriented, with a bias towards flexibility and impact.
• Have clear written and verbal communication.
• Care about the societal impacts of your work.

Responsibilities

• 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.
