About Anthropic

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

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. Found on 1752vc Careers, the job board for startup and VC roles.

  • 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
