Anthropic is an AI safety and research company that's working to build reliable, interpretable, and steerable AI systems. Backed by Accel, Bessemer and General Catalyst.
About the role
Our mission on the Connectivity team is to make Claude the most connected AI. As agents take on more real-world work, we're taking a leading role in defining how they get access to external systems — safely, with the right permissions, and in ways enterprises can trust. We ship standards and services used by claude.ai, Claude Code, Cowork, and the API. We own the MCP proxy that routes every tool call and the OAuth and token management that keeps connections authenticated.
What they're looking for
- Experience as a backend or platform engineer
- Familiarity with using AI tools as part of the software development process
- Take a product-focused approach to platform work and care about building solutions that are robust, scalable, and easy to use
- Take full ownership of your work — from design through build, deployment, and operations, to iterating on and improving your product
- Can navigate ambiguity and make sound technical decisions independently, and have ideally operated in both 0 → 1 and more mature team or company settings
- Experience operating production distributed systems, with an understanding of what reliability, observability, and incident response require at scale
