Lead Data Scientist

About this role

Lead Data Scientist – Knowledge Graph & Agentic AI

River Social | Los Angeles, CA (Remote-First)

Overview

River is building the individual intelligence layer for the AI era.

AI is the defining technology of our age, but it has a blind spot. Today's models are trained on the internet, not on you. They don't know what you want, what you value, or how to act on your behalf. River changes that.

We are building the technology that connects AI to the individual – a persistent, portable data identity that makes AI personal, attributable, and valuable. When your data creates value, you share in it. When an AI agent acts, it acts with your authority. When a brand reaches you, it's on your terms.

Our founding CEO brought MTV and NetJets to the European market, and we are backed by a number of technology company luminaries from Google, Sun Microsystems, and others. We are looking for a Lead Data Scientist to take full ownership of everything data science at River – from our personal data graph to our next-generation agentic AI systems. This is a foundational hire that will underpin our expanding team. You will be the person who defines how River understands, connects, and reasons over user data at scale, and who builds the data science function from the ground up.

Come join us on our mission to build individual intelligence, owned by you.
