About the Role
The Senior Inbound Seller Acquisition Manager is accountable for building and scaling a global inbound seller acquisition engine, covering the full journey from awareness → lead → sign‑up → first activation across 21 international markets. You will own both B2B demand generation and inbound seller sign‑up, ensuring we attract the right sellers through localised, high‑converting experiences, while accelerating speed to first sale.
