Applying to this role means you're applying to two of Adyen's departments, called Unified Platform and Financial Services solution. We’re hiring Software Engineers at both Level 2 and Senior levels, and have several teams actively looking for new colleagues.

We'll explore the best team fit together throughout the interview process.

Unified Platform 

The Unified Platform is at the heart of Adyen’s infrastructure, bringing together accounting, reporting, billing, pricing, reconciliation, and configuration into one streamlined experience. It enables us to stay agile and innovative while running a scalable, efficient business. As part of this initiative, we’re rethinking five core product areas:

The Financial Products solution is responsible for all financial products that we offer on top of payments processing to our customers. Examples of these are our Banking, Issuing, Fx, and Capital products.

  • Build APIs and tooling according to quality principles such as performance and code quality.
  • Collaborate across teams and time zones to get projects over the finish line.

Who you are:
