JOB PURPOSE

Looking to kick off your engineering career as a backend developer?

During this internship, you'll join our talent program designed to shape you into a productive developer, capable of working in a large team. We'll share all the knowledge we have and provide you with all the attention, feedback, GIFs, and challenges you need to grow into a standout professional.

In short, our goal is to help you reach your full potential.

A backend developer is the engineer that works behind the scenes, ensuring data flows seamlessly from system to system and powering the digital experiences users love. One moment you're connecting APIs with other backend systems like databases and making sure information is exactly where it needs to be. The next you're collaborating with front‑end colleagues, helping them bring designs to life.

Be ready to build the robust foundations that make innovation possible.

From day one, you'll be paired with a dedicated mentor for 1-on-1 coaching and join a team of passionate developers always ready to help. You'll be working on real client projects, giving you real life experience. By the end of your internship, you'll have gained valuable knowledge in the field and worked on projects for A-list clients. You will work side by side with other developers and your code will power actual websites.

Take it from us, your resume will be more than ready for a future in the digital industry.

Note: to be eligible for this internship, you are required to be living and studying in the Netherlands.

WHAT YOU WILL DO

• Dive into exciting projects for clients like BOLIA, Tikkie, Foot Locker, and bol.com.
• Work alongside experienced developers on real projects, learning and contributing directly from day one.
• Use different programming languages such as TypeScript, C#, Java, or Python.
• Move data around integrating different databases, services and CMS. You will make sure the right data is in the right place at the right time.
• Bring designs to life with data on all kinds of different devices in collaboration with front‑end colleagues.

Even if you don’t tick every box, that doesn’t mean we’re not a match. If you feel like this role could be right for you, just go for it and apply!

• You are super passionate about technology.
• You have a proactive attitude, are naturally curious, and are aware of the latest trends within our field.
• You have a great portfolio or GitHub you share with your application.
