As a team member you will have an important voice in the direction of the team. This rate is determined by a healthy balance between what does the team itself is important and what is requested by other departments of the team.

Development at Mollie

Tinkering with new solutions, disrupting markets and inclusiveness are core values Mollies. In its early years, Mollie was solely because of developers. Fifteen years later, still consists of roughly 50% of the staff of developers and techs. A logical consequence is that things that wannabe startups and boring enterprises should do their best so hard for Mollie are quite obvious.

Normal things. As you choose the tools you are going to do your job. MacBooks, ridiculous amounts or large screens and top-notch noise canceling headphones. We ensure that there is room in which you can focus on things that you are really happy: good features release where you worked heart and soul to you for example.

But unusual things. As we stand up for diversity and encourage you to be truly yourself. We invite you to improve the product with fresh ideas, to write professional code and to focus on the skills you want to improve. We let you focus on quality, yourself and the product. We are also blessed with an almost flat organization with minimal hierarchy. And we had been told about fresh lunches every day by our own chef prepared?
