Sanity - Senior Software Engineer, AI Developer Experience

• Advance our MCP server – add new capabilities, tools, and integrations that let AI agents interact deeply with Sanity's content platform. • Advance our MCP server • Build agentic developer tools – ship systems that can generate Sanity apps and studios, as well as frontend code with minimal human guidance. • Build agentic developer tools • Design and run evals – build evaluation suites using Braintrust to catch regressions, measure improvements, and make data-driven decisions about prompt and model changes. • Design and run evals • 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. • Build a Sanity • MCP app • 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. • Move across the stack daily • Ship production AI features – write clean, well-tested TypeScript and turn experiments into reliable capabilities that thousands of developers use. • Ship production AI features • Collaborate with the team – work closely with design, product, and engineering to iterate quickly and share what you learn. • Collaborate with the team • Based in Remote US or San Francisco / Bay Area – if you are in San Francisco/ Bay Area, you should be able to work at least 2 days a week from the office. • Based in Remote US • San Francisco / Bay Area • 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. • Strong TypeScript, React, and Node.js skills • 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. • Shipped AI-powered code to production • Actively using MCP in your workflow – you've enhanced your own development with MCP servers. Bonus if you've built one yourself. • Actively using MCP in your workflow • 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. • Fluent in the current AI landscape • Hungry and curious – you're obsessed with the craft, experimenting constantly, and energized by how fast this space moves. • Hungry and curious • Strong prompt intuition – you can "decode" why a model is hallucinating or ignoring instructions without relying solely on automated evals. • Strong prompt intuition • Collaborative and clear communicator – you work well with designers and product managers, and you can explain complex AI concepts simply. • Collaborative and clear communicator • Not sure you meet every requirement? If you're building in this space and can't stop thinking about what's next, we want to hear from you. • What we can offer: • What we can offer: • A highly-skilled, inspiring, and supportive team • Positive, flexible, and trust-based work environment that encourages long-term professional and personal growth • A global, multi-culturally diverse group of colleagues and customers
