Web Developer (MERN Stack)

We are hiring a Web Developer who builds production web applications on the MERN stack (MongoDB, Express, React, Node.js) and is equally comfortable building with Claude. You will ship customer-facing and internal web products, and you will design and integrate the AI layer behind them: Claude API calls, tool-using agents, MCP integrations, and multi-step automated workflows with human-in-the-loop checkpoints where the stakes require them. This is a hands-on engineering role. You will own features end to end, from data model and API design through React UI, AI integration, testing, deployment, and monitoring. You are expected to use AI coding tools such as Claude Code as a normal part of your workflow, and to review and test what they produce with the same rigour you would apply to any code.

• 4+ years of professional web development experience, with production work on the MERN stack (MongoDB, Express, React, Node.js).
• Strong JavaScript; TypeScript proficiency strongly preferred.
• Solid understanding of REST API design, HTTP, authentication (for example JWT or OAuth), and web security fundamentals.
• Hands-on experience with MongoDB schema design, indexing, and aggregation.
• Practical experience building with the Claude API or Anthropic SDK, including at least tool use (function calling) and streaming. Familiarity with structured outputs and prompt caching is a plus.
