Sanity is looking to build the full vertical for AI-native development, aiming to accelerate digital development and supercharge content operations efficiency by leveraging AI.
Requirements
- Strong TypeScript, React, and Node.js skills – you're comfortable moving between frontend and backend, and a pure specialist profile isn't what we're after.
- Shipped AI-powered code to production – whether at work or through side projects, you've built real things with OpenAI, Anthropic, or Vercel AI SDKs.
- Actively using MCP in your workflow – you've enhanced your own development with MCP servers. Bonus if you've built one yourself.
- Fluent in the current AI landscape – you can articulate the differences between Claude Opus 4.5, Gemini 3, and GPT-5.2, and you have opinions on tools like Cursor, Claude Code, Lovable, and v0.
- Strong prompt intuition – you can "decode" why a model is hallucinating or ignoring instructions without relying solely on automated evals.
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.
Other
- Based in San Francisco / Bay Area – able to work at least 2 days a week from the office.
- Hungry and curious – you're obsessed with the craft, experimenting constantly, and energized by how fast this space moves.
- Collaborative and clear communicator – you work well with designers and product managers, and you can explain complex AI concepts simply.
- Highly-skilled, inspiring, and supportive team
- Positive, flexible, and trust-based work environment that encourages long-term professional and personal growth
