Senior Product Engineer - US

Coefficient is evolving into an agentic data intelligence platform — where AI doesn't just retrieve data, but understands it, reasons about it, and takes action. At the core is a shared data world model: a unified, continuously updated understanding of a company’s data, business logic, and context. This allows our autonomous agents to operate with far more context than traditional tools—unlocking a fundamentally new way to work with data. We're looking for experienced Product Engineers who operate with high agency, strong ownership, and deep curiosity. This is not a scoped, ticket-driven role. You'll work directly with the founders to define product direction, build core systems, and ship end-to-end experiences.
