Software Engineer, RL Data

Anthropic's RL Data team builds the systems that produce high-quality reinforcement learning data for Claude: data collection pipelines, human feedback tooling, the execution environments RL tasks run in, and the quality assurance that keeps training data trustworthy at scale.

Requirements

• Strong software engineering skills and proficiency in at least one modern programming language — we mostly use Python and TypeScript, and care more that you pick new tools up quickly than that you know our exact stack
• Experience designing, building, and running backend systems or infrastructure
• Effective use of AI tools in your own day-to-day work
• Willingness to own problems end-to-end, including the parts that aren't engineering
• Proactive, open communication: you can be trusted to run a workstream, and to escalate early when something's off
• Comfort iterating quickly in ambiguous, fast-changing situations
• Care about the societal impacts of your work

Benefits

• Competitive compensation
• Optional equity donation matching
• Generous vacation and parental leave
• Flexible working hours
