• Integrations with Anthropic and OpenAI APIs including tool use and function calling.
• Internal tools that reduce manual hours across our design and development production process.
• Automation pipelines connecting WordPress, Figma, Google Workspace and our internal CMS.
• MCP server integrations as part of our broader AI stack.

What You Bring

• 2+ years building production software with Python or Node.js.
• Hands-on experience with LangChain, LangGraph, CrewAI, AutoGen or similar agent frameworks.
• Proven API integration work with OpenAI or Anthropic (function calling, tool use, streaming).
• Strong understanding of REST APIs, webhooks and basic cloud deployment.
• English sufficient for async written work with a US-based team.
