Full-stack Software Engineer

Who we are

At INFO, we love solving complex problems for our clients by designing and building digital products that support their core business. We bring together design, data, and technology expertise to create impactful solutions. We work in close, long-term partnerships with our clients. For example, we improved the customer and employee experience for the Stadsbank van Lening of the City of Amsterdam. We helped Growy scale up its concept for a fully automated vertical farm. With our bike management platform, around 6 million people each year are able to rent OV-fiets for the last part of their journey. These are just a few examples of how we help our clients drive sustainable innovation.

Our team consists of about 40 people, all passionate about digital innovation. We love asking tough questions and are driven by curiosity— key ingredients for staying ahead and helping our clients do the same.
