# Staff Software Engineer, Internal Products

About Anthropic 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. About the role As Anthropic grows, more of the work our own teams do every day runs through internal software, and that software has to keep up. We are building that software, and we are building it Claude-first: Claude should take on as much of the repetitive, multi-step work as it safely can, and people decide what needs a human. We’re looking for Staff+ full-stack engineers to drive this work. You’ll build across the stack: the products people use and the agents that work alongside them. You’ll work directly with the teams who rely on what you build. Many of these workflows write to business-critical data, so correctness matters as much as speed. This is a greenfield opportunity: you’ll shape the underlying systems, ship agents that take real work off people’s plates, and design how people and agents get the right context to make good decisions.
