Senior Software Engineer, AI Growth

Responsibilities

• Advance our MCP server – add new capabilities, tools, and integrations that let AI agents interact deeply with Sanity's content platform.
• Build agentic developer tools – ship systems that can generate Sanity apps and studios, as well as frontend code with minimal human guidance.
• Design and run evals – build evaluation suites using Braintrust to catch regressions, measure improvements, and make data-driven decisions about prompt and model changes.
• 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).
• Fluent in the current AI landscape.
• Strong prompt intuition.
• Collaborative and clear communicator.
