Staff Software Engineer, Claude Code

Anthropic Anthropic · AI Frontier · San Francisco, CA · Engineering & Design - Product

Software Engineer to build and maintain new agentic coding tools for developers, leveraging advanced LLM features like tool-use, chaining, and orchestration. Requires expertise in React, full-stack development, and hands-on experience with LLMs and prompt engineering. Experience with safety, security, or compliance requirements is a plus.

What you'd actually do

  1. Design, build, and maintain scalable features and infrastructure for AI-powered development tools
  2. Engage directly with developers inside and outside Anthropic to gather insights and improve user experience
  3. Collaborate with researchers to improve model capabilities through shared tools and evals
