Back-end Developer


Do you love to work on diversified projects? Keep on challenging yourself and never lose the chance to keep on growing? Take hold of this possibility as a back-end developer at Label A in Rotterdam!

Our team of 80 A-players works for big names like Greenwheels, Swapfiets, and Porsche. But also for less known start-ups that are ready to take over the (digital) world. With a Back-end, Front-end, Mobile, and Design team, we have everything we need to develop impactful products. Together with twenty other back-end developers at your side, you will be part of the biggest team within Label A, and work on the fundaments of these projects.

Our goal is to really make an impact with the products we create. We want to make the lives of our clients and their users a bit better, in any way possible. "Be eager" is one of our core values with a reason. At Label A, everybody has a strong drive to discover and innovate. Do you have any new ideas or techniques you want to use? Our innovation lab is the place to try things out! Are you ready to build the future with us?

Please note that if you are not a citizen from a European state and you do not have a work permit for the Netherlands, you can not apply for this position. 

Your specs

At Label A, we set up all our projects with Python. If you don't have any experience with Python yet but have developed in other languages - like PHP or Java? You know the basics, we'll teach you the rest!

We’re looking for this in our future back-end developer: 

  • You have a minimum of 2 years of experience with programming;
  • You are familiar with (using) design patterns. All of these ring a bell: MVC, Dependency Injection and Event-Driven Architecture;
  • You are interested in microservice patterns;
  • You’re fascinated with delivering high-quality code;
  • You are used to working with Scrum;
  • You are capable of understanding what a client wants;
  • You are a team player and have good communication skills;
  • It’s an advantage if you have an affinity with security.

How We Roll

We work hard and take our work very seriously, but there is always room for fun. Work hard, play hard! What can you expect?

Everyone is part of the Label A family! We look out for each other: why work 4 hours extra to finish the job, if you could finish it on time with the four of you?! We want you to grow within your role, but also as a person. From the moment you start, you will get workshops and coaching. But it doesn’t stop there, because once every quarter we have a recharge week to focus on what gives us energy and our goals.

We also like to hang out after work hours to play games, try out new sports together or work on side projects during our monthly hacknight. Cool idea in mind? You’ll always find people who will join you!
