Job summary

Responsibilities

Anthropic is looking for Software Engineers to join the Memory & Search team. We own how Claude remembers you and how it finds what it needs, across Claude.ai, Cowork and Claude Code.

• Design, build and ship memory and search experiences in Claude.ai, Cowork and Claude Code, owning them end to end from the backend service through the model's tools to the user…
• Run product experiments on the memory and search stack: form a hypothesis, build a demo, put it in front of real users, measure, and make a clear persevere-or-pivot call
• Shape how Claude uses memory and retrieval inside its agentic loop, including what the model stores, when it searches, how results are ranked and presented, and how the user…
• Define and track the metrics that tell us whether memory is actually making Claude more useful, and build the evaluations that keep quality honest as the system evolves
• Improve search relevance and recall across conversations and memories, working across embeddings, hybrid retrieval and ranking as well as the interface that presents results

• Experience building and operating user-facing products used by a large number of people, including the backend services behind them
• Experience building agentic systems or LLM-powered products, including tool use, retrieval and prompt or context design
• Strong programming skills in Python and TypeScript, with experience across backend services and web front ends
• A track record of taking a product or feature from an idea to launch, and iterating on it based on usage data and user feedback
• Experience defining product metrics and running experiments to make decisions
