Your job

At Tellow, you will become part of an ambitious and fast moving Product team. We love our code to be creative, scalable & reusable. We have TypeScript/Node microservices, a (to be phased out) PHP Symfony backend, a marketing website in React and our web app is built in Angular. We are true geeks who love to try out the newest tools and techniques, always picking the best tool to get the job done.

We're looking for an allround intern. Whether that's 50/50 frontend/backend or 20/80 or 80/20 that doesn't matter. Together with all the skills present in the team, a team effort ensures we will achieve our deliverables. We will help you to become a better developer, whether that's frontend, backend, UI/UX or sysops.

You will work closely with our CTO and developers to transform user learnings into product features/improvements. At Tellow, we care for quality and well-designed user experiences. 'Ship early and often’' is our development philosophy. We like to break up big challenges into smaller ones, deploying gradual product iterations and improvements numerous times every day.



  • Can code. Don’t worry: we speak your language. Coding is a state of mind ;)
  • Are pragmatic, dedicated and think in solutions.
  • Are always learning and improving yourself.
  • Care about quality. If it’s not the best, is it worth building?
  • Have excellent English verbal and written communication skills.


      • € 450,- internship allowance.
      • Possibility to do your graduation research within your internship.
      • A dedicated mentor available to you at all times as well as regular mentoring sessions with one of our Chiefs.
      • Strong focus on learning: we want you to walk away feeling capable and knowledgeable on the job market.
      • Working in a start-up atmosphere: lots of autonomy, a young and driven team and a fun office environment.
      • Travel allowance (when applicable).
      • Freedom to work from home or come into the office when it’s safe.
      • An open working atmosphere, in which you can give and receive honest feedback.

        Start date: ideally Summer 2020 but can be discussed. We’re looking for interns who can stay 3-6 months.

        Location: our lovely office at the Keizersgracht in Amsterdam, the tech capital of Europe!
