Back-end Developer 40hrs, Rotterdam


As a Back-end Developer, you are responsible for the back-end for our mobile- and web applications. You will set up a solid architecture and develop the back-end that will serve as the base for the rest of the team. The challenge is to build an architecture on which you can develop quickly, but that is also ready for the future. Both seniors and mediors are welcome. We are mostly looking for someone with a passion for back-end!

Who We Roll For

Everything make must simply work well, be reliable and look fancy. You’ll play an important role in this process. We only build great things for clients that make us ‘wow’. This could be clients with a rich audience, such as Porsche, Greenwheels, Nuon, Coca-Cola, Philips and Apollo Hotels, but also small start-ups that impress us.

Besides that, we don’t simply build what the clients asks us to. If we think an idea is dull, we’ll put our heads together to improve it. Our projects need to be challenging and we should be proud of what we have build when it ends. Only then you get passionated colleagues.

Your specs

 This is important to us:

You are passionate and do not only care about your project but also help your colleagues with theirs. Furthermore, you are not afraid to say something smart once in a while or speak up. We like someone that is strong at communicating and preferably has experience with big projects.

At Label A we set up all our projects with Python. It is essential that you are a real Python fan or motivated to learn it. Do you already have experience with other languages like PHP and Java? Then you know the basics, and we will teach you the rest!

  • We hope to find this in our future Back-end Developer:
  • You have a minimum of 3 years experience with programming
  • You are familiar with MVC pattern
  • You are interested in microservice patterns
  • You can abstract ideas
  • You find code quality important
  • You are used to working with Scrum
  • You are capable of researching and understanding what a user wants
  • You can understand the essence of a problem
  • You can fix issues with the help of your technical skills
  • You know the current security guidelines and know how to apply them
  • Bonus if you have an affinity with security  

How We Roll

A picture says more than a thousand words, but a video says even more. Of course, we work hard. We build cool things, absolutely. But we also make time for other fun activities, such as:

  • Hackathons
  • Dev Days
  • Workshops and theme months
  • Game things (in our game corner)
  • Going out together
  • Sporting days
  • Cool trips
  • Weekly meetings to get up to date on the newest techniques and project

And if you come up with something yourself, you’ll always find people that will join you. Everyone is part of the Label A family and you’re part of that as well. We’re there for each other. Why work 4 hours extra to finish the job if you could finish it on time with the 4 of you. We don’t have managers or directors so you can think and act freely (and you don’t have to account for a non-technical management, makes sense right?)

The Team

70+ developers and designers, spread out over two offices in Amsterdam and Rotterdam. A quite mixed group of people with hobbies that lie lightyears away from each other. And that’s what we like. We are your colleagues -front-end developers, back-end developers, mobile developers and designers- with whom you’ll be working with, with whom you’ll be building astonishing Android apps and with whom you’ll be spending 8 hours a day together. This makes it even more important that you’ll feel like home. And believe it or not, you will!
