About the role

  • Companies like Linear, Figma, Riot Games, Anthropic, Spotify, Arc'teryx and Morningbrew are using Sanity to power and automate their content operations.
  • You'll work closely with a designer, product manager, and fellow engineers to move fast, experiment constantly, and turn emerging AI capabilities into real products.
  • If you're the kind of person who stays up late tinkering with new model releases and thinks in terms of what's possible rather than what's been done before, this is your role.

Responsibilities

  • 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 https://blog.modelcontextprotocol.io/posts/2025-11-21-mcp-apps/ - create rich React interfaces on top of the MCP protocol for platforms like ChatGPT (using the new ChatGPT Apps SDK https://developers.openai.com/apps-sdk/build/chatgpt-ui) and Claude.
  • Apply prompt engineering craft - diagnose why models fail, steer them effectively, and build intuition for what makes prompts work at scale.
  • Collaborate with the team - work closely with design, product, and engineering to iterate quickly and share what you learn.
  • If you're building in this space and can't stop thinking about what's next, we want to hear from you.
  • Our AI Content Operating System gives teams the freedom to model, create, and automate content the way their business works, accelerating digital development and supercharging content operations efficiency.
  • In this role, you'll help build the full vertical for AI-native development at Sanity - from advancing our Model Context Protocol (MCP) server to shipping agentic systems that can scaffold Sanity apps, Studios, and full-stack frontends.
  • Actively using MCP in your workflow - you've enhanced your own development with MCP servers.

Requirements

  • 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.
  • Collaborative and clear communicator - you work well with designers and product managers, and you can explain complex AI concepts simply.

Nice to have

  • Sanity Agent Toolkit https://github.com/sanity-io/agent-toolkit - agent rules exposed via MCP, plus a Claude Code plugin with skills and slash commands.
  • Auto-configured MCP in the CLI https://www.sanity.io/docs/changelog/beb93f6c-7913-4ea7-8bbb-847ba7b51b19- the Sanity CLI automatically detects code editors and configures the MCP server for you.

Benefits

  • Bonus if you've built one yourself.
  • Positive, flexible, and trust-based work environment that encourages long-term professional and personal growth
  • Comprehensive health plans and perks
  • Competitive stock options program
