Horizon helps developers deploy, scale, and manage MCP servers with zero configuration — built for modern AI development workflows with production-ready infrastructure.This is a product engineering role with a strong design sensibility. You'll own features end-to-end — from understanding the user problem, to wireframing a solution, to shipping polished UI backed by solid full-stack implementation. You'll partner directly with our VP of Product, other product engineers, and early customers to turn field signal into working software fast.This role sits at the intersection of an emergent market where AI and LLM tooling are reshaping how development teams operate.
