Main responsibilities

• Design, build, and study reinforcement learning environments, rewards, and training data that improve Claude's capabilities in engineering and the applied sc…
• Create benchmarks and evaluation frameworks that measure model performance on realistic engineering and scientific workflows
• Develop simulation-based training environments and verifiers, working with domain experts to validate them against real-world data
• Develop approaches to long-horizon task completion, multi-agent collaboration, and complex reasoning essential for real engineering and research work
• Research how models can learn efficiently from experiments and real-world feedback
• Study how environments and rewards behave in large-scale training, including robustness, calibration, and generalization, so that training produces models th…
• Scale research ideas from prototype to production training runs
• Collaborate with domain experts and industry partners to build and test what Claude invents, designs, and engineers, and turn that feedback into training and…
• Help chart how Claude’s engineering capabilities reach real-world use: where they matter most, what stands in the way of adoption, and how that should shape …
• Proficiency in Python and hands-on experience with a modern machine learning framework such as PyTorch or JAX

Competencies an interviewer will look for

• Technical skill Core
  In the posting: “We're expanding our work on engineering and the applied sciences.” · “In this role, you'll work end to end across the model stack, developing training environments, rewards, data, and evaluations that measure and improve Claude…” · “A background in engineering or the sciences is a plus but not required.”
  Show it by: Names the tools, languages or systems used and how; Explains a technical choice and its trade-off.
• Problem solving Core
  In the posting: “The Discovery team at Anthropic is organized around the north star goal of building an AI scientist – a system capable of solving the long-term reasoning cha…” · “Ability to implement your own research ideas and diagnose problems in complex systems” · “Clear communication and a collaborative approach to solving problems”
  Show it by: Describes a real problem, the options considered and the one chosen; Shows how the cause was found, not just the fix.
• Communication Core
  In the posting: “Clear communication and a collaborative approach to solving problems” · “If you're ever unsure about a communication, don't click any links—visit anthropic.com/careers directly for confirmed position openings.” · “As such, we greatly value communication skills.”
  Show it by: Adapts the message to the listener; Gives an example of explaining something clearly in writing or speech.
• Teamwork and collaboration Core
  In the posting: “You'll collaborate closely with researchers, engineers, and partners across Anthropic and industry to build AI systems that can engage in all phases of resea…” · “Develop approaches to long-horizon task completion, multi-agent collaboration, and complex reasoning essential for real engineering and research work” · “Collaborate with domain experts and industry partners to build and test what Claude invents, designs, and engineers, and turn that feedback into training and…”
  Show it by: Says what they did inside a team, not only what 'we' did; Shows how a disagreement was handled.
• Data and analysis Core
  In the posting: “In this role, you'll work end to end across the model stack, developing training environments, rewards, data, and evaluations that measure and improve Claude…” · “Design, build, and study reinforcement learning environments, rewards, and training data that improve Claude's capabilities in engineering and the applied sc…” · “Develop simulation-based training environments and verifiers, working with domain experts to validate them against real-world data”
  Show it by: Uses a number to describe the situation or the result; Explains what the data showed and what was done with it.
• Attention to detail and quality Core
  In the posting: “Our goal is to contribute to training Claude to invent, design, and engineer across every discipline and scale, reliably and safely: new manufacturing and ex…” · “Your safety matters to us.” · “This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, S…”
  Show it by: Gives an example of an error caught before it caused harm; Names the check or standard they used.
• Planning and organisation Core
  In the posting: “The Discovery team at Anthropic is organized around the north star goal of building an AI scientist – a system capable of solving the long-term reasoning cha…” · “Help chart how Claude’s engineering capabilities reach real-world use: where they matter most, what stands in the way of adoption, and how that should shape …”
  Show it by: Shows how priorities were set when everything was urgent; Mentions deadlines met and how.
