Member of Technical Staff; Rust, Search & Database Engines

Building data-driven AI applications and agents is too complex, even for advanced developers.

This new generation of applications need fast, secure access to data across disparate systems, the ability to search and reason over that data, and infrastructure that’s reliable enough to run in production. Today, teams often need to piece together query engines, search systems, caches, and AI tooling, adding significant complexity along the way.

At Spice AI, we simplify this by unifying query federation, search, and AI into a single runtime for building intelligent applications. Our mission is to make building AI-powered software as easy as building a modern web application and help developers build the next generation of applications. We offer both open source and fully managed cloud deployments.
