Senior AI Systems Engineer - Knowledge Bases & Agent Tools

Sanity.io is hiring a senior engineer for Agent Foundations, the team building how agents work with structured content. You'll own the domain end to end, collaborating with product and design to decide what to build next.

The role emphasizes AI systems in production, knowledge bases, and MCP endpoints, with a focus on scalable, reliable tooling. You'll work across frontend, APIs, and backend (Go), contribute to user-facing and internal tooling, and influence how agents query data and use tools.
