Senior Software Engineer, Content Agent

We're hiring a senior engineer for Content Agent - Sanity's operations layer for structured content. It's the system that turns content work (bulk edits, audits, translation, publishing) into things an agent can actually run. It lives in Dashboard, Studio, Slack, and behind a headless API. If you've spent time on AI systems that have to hold up for real users, not just in a demo, read on.

At Sanity, we build an AI-powered content operating system that lets teams model, create, and automate content the way their business actually runs. SKIMS, Figma, Riot Games, Anthropic, COMPLEX, Nordstrom, and Morningbrew run their content operations on it.

Content Agent is the part of the product that understands structured content - schemas, references, field types, validation rules - and can be trusted to operate on it correctly. You'd be doing full-stack product work in TypeScript and React: MCP tools and integrations, agent orchestration, system prompts, evals to make the whole thing more reliable. Engineers on this team own their domain and work closely with product on what gets built next.

WHAT YOU'D BE DOING:

- Full-stack product work: React interfaces in Dashboards, APIs, backend services.

- MCP tools and integrations that extend what the agent can do.

- Agent loops: the orchestration logic that decides what the agent does, in what order, and when to bring a human in.

- System prompts. We treat these as real engineering artifacts, not a note at the top of a file.

- Evals and experiments to measure and improve reliability in real usage.

- GROQ, Sanity's content query language - using it to give the agent a deep understanding of structured content.

- Shaping what Content Agent becomes, with product and design. There's a lot of latitude here.

ABOUT YOU:

- Location: London, UK or Oslo, Norway (in-office 2–3 days/week)

- Strong TypeScript and React, comfortable across the stack (frontend, APIs, backend). You don't want to be boxed into one layer.

- You...
