AI Application Engineer I

At Mollie, we’re on a mission to make payments and money management effortless for every business in Europe. 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. In this role, you will help design, build, integrate, and scale AI-powered applications and workflows that create direct impact across the business. You will work closely with Machine Learning Engineers as well as with Application Engineers across different Domains and Teams, to deliver pragmatic agentic AI solutions for both internal users and Mollie customers. This role is a strong fit for an engineer who enjoys applied AI, product integration, and building useful systems with modern tooling. The focus of the role is not model research or training deep learning systems from scratch. Instead, it is about using existing AI models, platforms, and open-source tools to create reliable, production-minded AI applications that help Mollie further its mission to eliminate financial bureaucracy.
