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. In September 2026, we merged more than 30,000 changes per day. Writing a change is fast now, and the hard part is knowing what is 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 strong background in backend or infrastructure 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

Design, build, and operate the tools that help product teams ship faster
Own the technical strategy and roadmap for your area, and make sure its hardest problems get solved, by you or through others
Define what it means to trust a change, especially changes written by Claude, and build the tooling that holds the bar throughout the software development lifecycle
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
Move between building new tools and improving the shared systems that teams already depend on, as priorities shift

You might be a good fit if you

Experience building and operating backend services or infrastructure in production, in Go, Python, Rust, or TypeScript
Deep experience with developer tooling, CI/CD, test infrastructure, or deployment systems
Experience leading large, complex technical projects across teams, from an ambiguous problem to a solution developers adopt
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
Experience measuring developer productivity and using the data to decide what to build
A point of view on how software engineering changes as agents write more of the code
