Senior Full Stack Engineer, AI Developer Experience

About the Role

At Sanity.io , we’re building the future of AI-powered Content Operations. 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. Companies like SKIMS , Figma , Riot Games , Anthropic , COMPLEX , Nordstrom , and Morningbrew are using Sanity to power and automate their content operations.

As an engineer working on AI applications at Sanity, you will be at the forefront of the AI-driven evolution in content management. You’ll join a small, cross-functional team (working closely with a designer, product manager, and another engineer) to imagine and build the next generation of AI-powered features and agents for the Sanity platform, leveraging new and emerging AI products and tools.

In this role, you will use AI technology to build practical product capabilities that help our users. You will focus on building AI-driven features and agents – for example, leveraging LLMs to infer structure from unstructured content, and enhancing our Model Context Protocol (MCP) server to enable deeper AI integration with Sanity’s content platform. This is a highly collaborative and hands-on position : one day you might be prototyping a new content‑aware AI agent, and the next day you’ll be shipping a polished feature that thousands of users rely on. If you’re excited about solving complex problems at the intersection of content and AI (and charting new territory in the process), then this role is for you.

Based in San Francisco / Bay Area and able to work at least 2 days per week in our San Francisco office.

Responsibilities

• Design and build AI-driven features and agents that revolutionize how content is created, structured, and delivered within the Sanity platform.
• Leverage LLMs to analyze unstructured content (e.g. plain text) and infer structured data and metadata, making content more organized and “AI-ready.”
• Enhance our Model Context Protocol (MCP) server, adding new capabilities and tools so that AI agents can seamlessly interact with Sanity’s content lake and perform complex content operations.
• Work closely with design and product to prototype intuitive user experiences that blend AI automation with human oversight, iterating on feedback to get it just right.
• Apply cutting‑edge AI research in practical ways – from clever prompt engineering to optimizing how we handle large content datasets – and turn these innovations into reliable, scalable product features.
• Write clean, well‑tested code primarily in TypeScript (Node.js).
• Collaborate with fellow engineers to share knowledge and establish best practices for AI development, ensuring the solutions we ship are robust, ethical, and maintainable at scale.
