'Ship early, ship often' is our philosophy. We like to break up big challenges into smaller ones, deploying gradual product iterations and improvements numerous times every day.
We uphold code quality through thorough and cooperative peer reviews, CI/CD build pipelines, and gradual feature roll-outs. In other words, we do everything to make sure you feel comfortable pushing your changes to production on a daily basis.
We come from a monolithic background, with our core systems being written in PHP and Java. As our company started to scale up rapidly, we have scaled our infrastructure along with it by employing queueing systems, service oriented and serverless architecture. For current and future services, we use languages like Java as well.
Mollie’s frontend landscape consists of multiple apps, and each application has its own setup, which is optimised for the app’s purpose. Think of our merchant dashboard, API documentation, mobile apps, etc.
In general, our apps are written using TypeScript, in React. We work with flexible and reusable components, have an extensive UI library that we maintain internally, and are always looking for parts of the codebase that we can open-source and share with the community.
Kindly note that relocation support is not offered for candidates outside of Europe for this role.
