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 a 850-strong team of product, finance, support, commerce, and engineering specialists working across Europe – from Lisbon to London

Our Milan Hub:

In 2023, we successfully launched a new hub in one of the most vibrant cities in Europe: Milan! Since its inception, the Milan hub has been consolidated and continues to grow at a fast pace, contributing significantly to Mollie’s mission with multiple passionate agile engineering teams that will innovate, build, and enhance our portfolio of next-generation payment products. You'll work in a cross-functional team (Data, Machine Learning, Platform and Product) to accelerate our product delivery.

You will collaborate with engineers from many teams across Mollie to make Spring Boot services a first-class citizen within Mollie. This is a unique opportunity to be involved in helping Mollie adopt Spring and Java from being a PHP environment only a couple of years ago, shaping the future of Java development at Mollie.

Our architecture

Mollie’s Java platform is organised in a monorepo structure, with many services being developed, deployed and tested as part of a single GitLab repository. We use Maven and GitLab to test, package, and ArgoCD to deploy our applications to GKE on GCP with our infrastructure being managed by Terraform and Helm. All our applications are developed using Spring Boot, running on the latest JVM.

Besides Java, Mollie supports a large codebase of PHP, which supports large areas of the business, with engineers working in either or both.

• Experience in developing Java applications and libraries.

• Knowledge of the JVM, Java and Spring Boot.

• You know how to roll out changes across multiple teams, and how to work with CI/CD pipelines and deployments.

• You like to work with others either supporting the journey of new developers, or taking ideas from proof of concept to production-ready solutions.

• You are willing to learn or already have knowledge of PHP, providing empathetic support to people working in both environments
