If you have traveled to work by public transport or you have bought something in the store or at the gas station, you are guaranteed to come across one of the many smart solutions from this software company. Blockchain, contactless payment, NFC, mobile devices; there is an increasing demand worldwide for these types of solutions and that is why they are growing steadily with this increasing demand.
Here they have been building high-availability, scalable and super-secure software products for many years. These are used 24/7 by thousands if not millions of people. These systems often run at the heart of our infrastructure, but they are always used outside of our national borders.
The work is mainly done from their beautiful office in Haarlem, which means that you almost always work well with your software colleagues based on Scrum. These are real craftsmen with a lot of passion for quality software. That way you can do a lot of sparring and work hard on your own development. Yet the culture here is very relaxed, open and no-nonsense with a good work-life balance. And that is reflected in the pleasure and extremely low turnover.
