We are seeking an experienced relationship and account management leader to take ownership of wholesale trade customers once commercial deals have been signed. This role is focused on ensuring that signed opportunities translate into successful implementation, sustained customer adoption and measurable GDV growth. The successful candidate will act as the post-sale commercial owner for key wholesale trade relationships, working closely with customers, internal delivery teams, issuers, acquirers, and other partners and local market teams to move deals from contract signature into live usage and ongoing expansion. This is not a pure sales origination role. It requires strong relationship management, implementation discipline and commercial growth capability, with the ability to unlock additional payment volumes once the initial proposition has been agreed.
