We provide a simple and clear payment API, which enables webshop and app builders to implement more than ten different payment methods in one go. In the first few years of existence, Mollie was a developer-only adventure, and about 15 years later devs and techs still comprise roughly 45% of all staff. As a natural consequence, Mollie still is—and aims to remain—highly tech-minded. We take a developers-first approach to our products and internal development strategy, something that both our customers and our developers appreciate. This focus on the technical side can be found in various things. For example, you pick whatever tools you want to use to get the job done. MacBooks, absurdly large screens, top-notch noise-canceling headphones, and whatever other equipment makes your nerd-boat float. We go to great lengths to create a space that allows you to focus on the things that will make you happy: shipping great features you helped dream up and build. We don’t have code monkeys, but we do give you a problem and trust that you will create an outstanding solution. We invite you to influence the product with fresh ideas, to be a crafts(wo)man producing beautiful code, to focus on skills you want to improve, to enjoy flexible employment and really take part. We invite you to focus on quality. Quality of both yourself and the product. Take a look at our engineering blog to find out more: https://blog.mollie.com/engineering/home
