Desirable

• We are looking for Research Engineers to help us redesign how Claude interacts with external data sources
• Many of the paradigms for how data and knowledge bases are organized assume human consumers and constraints
• Your job will be to design new architectures for how information is organized, and train language models to optimally use those architectures
• Designing and implementing from scratch new information architecture strategies
• Performing finetuning and reinforcement learning to teach language models how to interact with new information architectures
• Building “hard” knowledge base eval sets to help identify failure modes of how language models work with external data
• Designing and evaluating advanced agentic search capabilities

• Applications will be reviewed on a rolling basis
