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.\nAt 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.\nContent 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.\nWhat you'd be doing:\nFull-stack product work: React interfaces in Dashboards, APIs, backend services.\n\nMCP tools and integrations that extend what the agent can do.\n\nAgent loops: the orchestration logic that decides what the agent does, in what order, and when to bring a human in.\n\nSystem prompts. We treat these as real engineering artifacts, not a note at the top of a file.\n\nEvals and experiments to measure and improve reliability in real usage.\n\nGROQ, Sanity's content query language - using it to give the agent a deep understanding of structured content.\n\nShaping what Content Agent becomes, with product and design. There's a lot of latitude here.\n\nAbout you:\nLocation: London, UK or Oslo, Norway (in-office 2-3 days/week)\n\nStrong TypeScript and React, comfortable across the stack (frontend, APIs, backend). You don't want to be boxed into one layer.\n\nYou'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.\n\nYou 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.\n\nYou write well and you care about why one phrasing works where another doesn't. An agent's instructions are prose running on a system that reads literally. Writing them well takes a feel for how language lands, not just what it says - who \"you\" refers to, what's implied versus explicit, how a sentence will actually be parsed.\n\nYou'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 is what matters. You've moved past \"it compiles or it doesn't.\"\n\nReal experience with, or real curiosity about, MCP, tool-use patterns, and agent architectures.\n\nYou care about craft in code, in writing, and in the products you ship.\n\nNobody checks every box. We're especially interested in people from non-traditional backgrounds - writing, interaction design, liberal arts - who've built real engineering skills on top. Some of the best agent work we've seen comes from people who understand language and how people actually work, not just systems architecture. If this sounds like you, send something in.\nWhat we can offer:\nA highly-skilled, inspiring, and supportive team\n\nPositive, flexible, and trust-based work environment that encourages long-term professional and personal growth\n\nA global, multi-culturally diverse group of colleagues and customers\n\nComprehensive health plans and perks\n\nA healthy work-life balance that accommodates individual and family needs\n\nCompetitive stock options program and location-based salary\n\nWho we are: \nSanity.io is a modern, flexible content operating system that replaces rigid legacy content management systems. One of our big differentiators is treating content as data so that it can be stored in a single source of truth, but seamlessly adapted and personalized for any channel without extra effort. Forward-thinking companies choose Sanity because they can create tailored content authoring experiences, customized workflows, and content models that reflect their business.\nSanity recently raised an $85m Series C led by GP Bullhound and is also backed by leading investors like ICONIQ Growth, Threshold Ventures, Heavybit and Shopify, as well as founders of companies like Vercel, WPEngine, Twitter, Mux, Netlify and Heroku. This funding round has put Sanity in a strong position for accelerated growth in the coming years.\nYou can only build a great company with a great culture. Sanity is a 200+ person company with highly committed and ambitious people. We are pioneers, we exist for our customers, we are hel ved, and we love type two fun! Read more about our values here!\nSanity.io pledges to be an organization that reflects the globally diverse audience that our product serves. We believe that, in addition to hiring the best talent, a diversity of perspectives, ideas, and cultures leads to the creation of better products and services. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, marital status, disability, or gender identity.","description_format":"text","description_chars":5481,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Stock options"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"},{"name":"Norway","iso":"NO","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Commerce","Cybersecurity","CMS & Digital Experience Platforms","Operating Systems"],"lifecycle":[{"event":"open","at":"2026-04-21T13:22:31Z"}],"visa":[],"liveness":{"score":19,"band":"cold","label":"Long shot","p_open":1,"p_active":0.672,"p_room":0.28,"age_days":190,"expected_fill_days":83,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/sanity-io-senior-software-engineer-content-agent","json_url":"https://alion.io/job/sanity-io-senior-software-engineer-content-agent.json","meta":{"generated_at":"2026-10-29T12:55:53Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":19469,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":57765},"rest":"https://alion.io/mcp/rest/get_company?id=57765"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsanity-io-senior-software-engineer-content-agent"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fsanity-io-senior-software-engineer-content-agent"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fsanity-io-senior-software-engineer-content-agent"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/sanity-io-senior-software-engineer-content-agent\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsanity-io-senior-software-engineer-content-agent"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":161468}},{"tool":"search_jobs","arguments":{"company":"sanity.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":161468},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
