Descripción del empleo

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: building React interfaces in Dashboards, APIs, and backend services.
• MCP tools and integrations that extend what the agent can do.
• Agent loops: orchestrating logic to decide what the agent does, in what order, and when to bring a human in.
• System prompts: real engineering artifacts rather than notes.
• Evals and experiments to measure and improve reliability in real usage.
• GROQ, Sanity's content query language, to give the agent deep understanding of structured content.
• Shaping what Content Agent becomes, working with product and design, with latitude and ownership.

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've shipped LLM‑based systems in production; you know the hard part isn't getting a model to do something once, it's getting it to do the right thing for every user who shows up.
• You think in systems; given a new agent capability, you think through user intent, edge cases, failure modes, and what that means for the architecture (what the agent knows, what tools it has, when it escalates).
• You write well and care about why one phrasing works where another doesn't; writing agent instructions requires a feel for how language lands.
• You're comfortable with probabilistic systems; improving an LLM product means running experiments, designing evals, reading results statistically, and not chasing individual failures when the aggregate trend matters.
• You have real experience or curiosity about MCP, tool‑use patterns, and agent architectures.
• You're comfortable with craft in code, writing, and in the products you ship.
• We're especially interested in people from non‑traditional backgrounds—writing, interaction design, liberal arts—who've built real engineering skills on top.

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.
• Comprehensive health plans and perks.
• A healthy work‑life balance that accommodates individual and family needs.
• Competitive stock options program and location‑based salary.

Who we are:

Sanity.io is a modern, flexible content operating system that replaces rigid legacy content management systems.
