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

• Evaluating & solving complex problems across the stack

• Putting your skills to the test and allowing yourself to grow and learn rapidly

What you'll bring

• A minimum of 5 years experience in developing large-scale web applications

• Some professional grasp of working with the public cloud (either GCP, AWS or Azure)
