Implementation Manager - Spend

As the Implementation Manager for our Spend Team, you will own the end-to-end delivery of complex Spend and corporate card implementations that bring our global spend management products to life for enterprise and high-growth customers across EMEA. You will turn agreed business requirements and solution designs into actionable implementation plans, orchestrating cross-functional teams and external stakeholders to deliver on time, on scope, and to a high quality bar. You’ll sit at the intersection of Sales, Merchant Services, Solutions Engineering, Product, Operations, Risk and external partners (e.g. networks, processors, manufacturers), ensuring that every phase from pre-sale through go-live and early spend activation runs smoothly. This role is based in Amsterdam (3 days in office), with implementation coverage across EMEA.

Nice to have

Hands-on experience working with or alongside integration engineers, solution architects, or technical program managers on API-based integrations, including familiarity with common web, SSO, and ERP integration concepts.; Formal training or certification in project management or agile delivery (e.g. PMP, PRINCE2, Scrum Master), and comfort setting up operating rhythms such as stand-ups, steering committees, and executive readouts.; Experience managing strategic or enterprise accounts as part of a broader account team, including navigating commercial sensitivities while protecting delivery quality and scope.; Ability to thrive in a fast-moving, ambiguous environment, balancing structured methodologies with pragmatic decision-making to keep complex projects moving forward.
