For our office in Amsterdam / Rotterdam, we are looking for a JavaScript Developer who masters ReactJS!

As a JavaScript Developer, the concepts of “quality”, “speed” and “scalability” are central and you know your way around them. Thanks to your work, the site structure grows effortlessly with the platform and the business of the customer. You enjoy building client apps and you can, of course, do it well. You can design the best solutions for our clients and stand behind it. You are experienced enough that nothing surprises you and you can help and mentor others.

You will work in an amazing team that is young, ambitious and professional. With this bunch of creatives, we created mobile apps for clients like Eneco, Aegon, Kempen, BPD, Nationale Opera & Ballet, Triumph Motorcycles and ABN AMRO.

Yes, we are eager to bring on board the most talented experts in the game. But we are also looking for a perfect Dept-fit. Someone who is eager to learn and strives towards a better world, takes the stage, is a futurist at heart, and someone who is down to participate in curling activities once in a while. We strongly support diversity and are committed to creating an inclusive environment for all employees. Ultimately, we are looking for a unique individual who is able to strengthen our collective.
