Jobs

Security Engineer, Detection & Response

Safeguards Enforcement Analyst, Safety Evaluations

Anthropic's Safeguards team is responsible for enforcing our policies, protecting users, and ensuring our platform is not misused.

Research Scientist, Life Sciences

We're seeking an exceptional Research Scientist to join our Life Sciences team at Anthropic. Our team is building a world-class research group focused on making Claude a superhuman life sciences research assistant.

Research Scientist, Interpretability

To learn more about the skills we look for and how to prepare for this role, see our blog post - So You Want to Work in Mechanistic Interpretability?

Research Engineer, Visual Knowledge Work

We're looking for a research engineer who believes that visual and spatial reasoning are core to fully unlocking the capabilities of LLMs.

Research Engineer, Universes

The Universes team within Research is responsible for training AI models to perform complex, difficult, long-horizon agentic tasks in ultra-realistic settings.

Research Engineer / Scientist, Alignment

Our blog provides an overview of topics that the Alignment Science team is either currently exploring or has previously explored.

Research Engineer, RL Scaling Science

This role lives at the boundary between research and engineering. The problems are open, the experiments run at frontier scale, and the path from a robust result to production is short.

Research Engineer / Research Scientist, Tokens

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts.

Research Engineer/Research Scientist, Pre-training

Research Engineer, Production Model Post-Training

You'll work at the intersection of cutting-edge research and production engineering, implementing, scaling, and improving post-training techniques like Constitutional AI, RLHF, and other alignment methodologies.

Research Engineer, Pretraining

Anthropic is at the forefront of AI research, dedicated to developing safe, ethical, and powerful artificial intelligence.

Research Engineer, Performance RL (Reinforcement Learning)

You'll need to know accelerator performance well to turn it into tasks and signals models can learn from.

Research Engineer, Model Evaluations

We're looking for Research Engineers to build the evaluations that tell us - and the world - what Claude can actually do.

Research Engineer, Machine Learning (RL Velocity)

The RL Velocity team owns the efficiency and reliability of our RL Science stack - the infrastructure, tooling, and systems that let researchers iterate quickly on training runs.
