Role We are looking for a Head of CRO to build and scale a best‑in‑class experimentation engine across web and mobile apps. This role goes beyond traditional CRO.

You will operate at the intersection of Product, Marketing, and Engineering, driving fast iterations that directly impact revenue and user satisfaction.
