The role involves collaborating closely with researchers and engineering teams, owning the reliability of research runs, and contributing to design decisions that shape large‑scale RL at Anthropic.

Salary

USD 500,000 - 850,000

Requirements

Skills

  • Strong software engineering fundamentals and a track record of building performant, reliable systems
  • Experience working on ML infrastructure, distributed systems, or research tooling
  • A bias toward shipping and iterating quickly
  • Comfortable operating across the stack, from low-level performance work to RL algorithms
  • A track record of operating at the edge of research and infra in a fast-moving environment
  • Large-scale distributed training experience (RL, pre-training, or post-training)
  • Familiarity with JAX, PyTorch, or similar ML frameworks
  • Bachelor’s degree or an equivalent combination of education, training, and/or experience
  • Field relevant to the role as demonstrated through coursework, training, or professional experience

Responsibilities

  • Build and improve the RL training infrastructure that researchers depend on day‑to‑day
  • Identify and remove bottlenecks across the RL stack: debugging, profiling, and rearchitecting where needed
  • Partner closely with researchers and with adjacent engineering teams (inference, sandboxing, and many more) to understand pain points and ship tooling that makes them faster
  • Own the reliability and performance of research runs end‑to‑end
  • Contribute to design decisions that shape how Anthropic does RL at scale
