Financial Products

Adyen is expanding beyond payments by building an entire suite of embedded financial services tailored for platforms, marketplaces, SaaS businesses, on-demand platforms, and crowdfunding platforms. Our team’s mission is to enable these platforms to manage their global payments and financial services seamlessly through API integrations or hosted solutions.

With our solutions, platforms can:

• Run onboarding, verification, and compliance processes across multiple markets.


• Manage payments and trigger faster payouts and bank transfers in all preferred currencies.


• Offer value-added services like capital lending and the issuing of payment cards and bank accounts.

• You will identify and improve parts of the platform to make it more robust and scalable.


• Collaborate across teams and time zones to make things happen, review code and be open to feedback.


• As an engineer you will help our core financial data processes and work on our finance infrastructure, to keep it scalable, reliable and secure.

Who you are:

• You are flexible, a team player, and someone who understands the bigger picture.


• You are able to take ownership and lead a project.


• We are an international team and our working language is English, so you speak it fluently in both technical and non-technical contexts.
