Full Stack Engineer II

Your opportunity

At Mollie, we’re on a mission to make payments and money management effortless for every business in Europe.

We started 20 years ago when we launched a more direct, affordable way for companies to get paid. That provided an alternative to the frustrating, overpriced solutions that banks offered at the time.

Today, we serve more than 250,000 businesses across Europe with an all-in-one solution that simplifies payments and money management. And we’re an 850-strong team of product, finance, support, commerce, and engineering specialists working across Europe – from Lisbon to London.

We are looking for an experienced full-stack engineer to join our Payment Foundations team. Our goal is to make services that facilitate the processing of payments (e.g., Settlement Processing & Reconciliation, Payment Method Activation) scalable, manageable, and fault-tolerant.

Our team will consist of an Engineering Manager, a product manager, and 3 more engineers working across two different locations (Amsterdam and Lisbon). There is also a great opportunity to collaborate with UI engineers across domains on setting good UI principles and creating reusable components.

The team offers great opportunities for people who like the challenge of creating something new from the ground up and solving the problems of a business by defining and discovering processes and modeling the domain along the way.
