Software Engineer, Memory & Search

<div class="content-intro"><h2><strong>About Anthropic</strong></h2> <p>Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.</p></div><h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold" data-sourcepos="5:1-5:18;181-198">About the role</h2> <p class="font-claude-response-body break-words whitespace-normal" data-sourcepos="7:1-7:475;200-674">Anthropic is looking for Software Engineers to join the Memory &amp; Search team. We own how Claude remembers you and how it finds what it needs, across Claude.ai, Cowork and Claude Code. That spans the user-facing experience (what Claude remembers, how people see and edit it, how search surfaces the right conversation) and the shared infrastructure underneath it, the memory service, indexing, retrieval and vector search.</p> <p class="font-claude-response-body break-words whitespace-normal" data-sourcepos="7:1-7:475;200-674">Memory is one of the biggest levers on whether Claude feels like it knows you. We recently moved memory from a periodically synthesized summary to a dynamic, editable, on-demand system, and then unified it so the same memory follows you across products. Search went from a top user complaint to something people rely on to find past work. The platform is now in place, and the next phase is finding the product form factors that make memory the most compelling and sticky part of using Claude.</p> <p class="font-claude-response-body break-words whitespace-normal" data-sourcepos="7:1-7:475;200-674">That is why we are hiring product engineers. The team is strong on infrastructure, and we want people who have shipped user-facing products at scale, have a sharp sense for what makes a product feel good, and have built agentic systems where the model, the tools and the user interface have to work together. You will run short, demo-driven experiments on top of the memory and search stack, decide what to keep based on real usage, and help the whole team think like a product team. If you have founded a company, been an early engineer at a startup, or taken a product from zero to one, you will recognize the way we want to work.</p> <p class="font-claude-response-body break-words whitespace-normal" data-sourcepos="7:1-7:475;200-674">This is a trust-sensitive surface. Memory touches privacy, consent and enterprise controls, so you will work closely with product, design, privacy, legal and safeguards, and you will be expected to treat those constraints as part of good product design rather than obstacles to it.</p> <h2 class="text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold" data-sourcepos="11:1-11:24;1119-1142">Key responsibilities</h2> <ul
