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 of May 2026, Claude authored more than 80% of the code we merge . Writing a change is fast now, and the hard part is knowing it's correct and safe to ship. Platform Acceleration builds the internal tools that close that gap for Anthropic's product engineers, who own the Claude API, our SDKs, and the rest of the Claude Platform. We work like a small product team whose customers are other Anthropic engineers. We're looking for Staff+ engineers with a backend and infrastructure background who care about developer experience and have built tools other engineers rely on. We prefer candidates who can work from our San Francisco office, and we'll also consider candidates based in Seattle. What you'll do • Own the technical strategy and roadmap for your area, and make sure its hardest problems get solved, by you or through others • Stay hands-on: design, build, and operate the tools that help Platform teams ship code faster • Define what it takes to trust a change, including changes written by Claude, and build the tooling that holds that bar before and after merge • Build agents that take on repetitive engineering work, such as diagnosing failures, fixing broken tests, and running migrations • Embed with partner teams to find their biggest sources of friction, validate a solution with them, and turn the fix into a product other teams can adopt • Measure developer experience and adoption, and use the data to decide what to build next • Move between building new tools and improving the shared systems teams already depend on, as priorities shift You might be a good fit if you: • Experience building and operating large-scale backend services or distributed systems in production • Proficiency in Go, Python, Rust, or TypeScript • Deep experience with developer tooling, CI/CD, test infrastructure, or deployment systems • Experience with cloud infrastructure and container orchestration • Experience leading large, complex technical projects across teams, from an ambiguous problem to a tool people use • Clear written and verbal communication, with experience supporting internal partner teams • Interest in Anthropic's mission of building safe, beneficial AI Preferred qualifications: • Experience at a startup or on a similarly small team, taking a product from zero to one and talking directly to your users • Substantial experience with agents that do engineering or other technical work • Experience building widely adopted CLI tools, developer-facing services, GitHub automation, or open source developer tools • Depth in progressive delivery, observability, VM orchestration, sandboxed execution, or workflow orchestration • Experience working in a large monorepo • Enough full-stack ability to put a usable interface on your tools • A point of view on how software engineering changes as agents write more of the code Deadline to apply: Non
