## Job Description

## Responsibilities

- Build a Sanity MCP app – create rich **React** interfaces on top of the MCP protocol for platforms like **ChatGPT** (using the new ChatGPT Apps SDK) and **Claude**.
- Move across the stack daily – one day you're designing a new MCP tool, the next you're polishing a **React** component or deploying a new microservice.
- Apply prompt engineering craft – diagnose why models fail, steer them effectively, and build intuition for what makes prompts work at scale.
- Ship production AI features – write clean, well-tested **TypeScript** and turn experiments into reliable capabilities that thousands of developers use.
- Collaborate with the team – work closely with design, product, and engineering to iterate quickly and share what you learn.

## Requirements
- Strong **TypeScript**, **React**, and **Node.js** skills – comfortable moving between frontend and backend.
- Shipped AI-powered code to production – built real things with **OpenAI**, **Anthropic**, or **Vercel AI SDKs**.
- Actively using MCP in your workflow – enhanced your own development with MCP servers (bonus if built one yourself).

- Strong prompt intuition.
- Collaborative and clear communicator.
