Sanity

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. Sanity Content Agent is where AI meets structured content - an intelligent assistant that deeply understands each customer's content model, follows references like an experienced team member, and combines web research with internal content knowledge in a single conversation. Sanity is uniquely positioned for this moment: we already have a scaled Content Lake holding our customers' structured content, which becomes rich context that generic AI tools simply can't match. Your team will push the boundaries of what's possible when AI truly understands content: auditing thousands of documents in seconds, surfacing inconsistencies before customers do, and generating perfectly structured documents that respect complex validation rules. With a strong and growing team of 4 engineers and room to scale as the product grows, you'll shape the AI capabilities that turn hours of content work into minutes. You'll balance the technical challenges of LLM integration and agentic workflows with the product sensibility to make AI that content teams actually trust.
