Medior Front-end Developer | Career Website Building | Endouble | Amsterdam

We’re looking for Front-end Developers, solution solvers, that always strive for cleaner, better quality code. Sound like you? Then read on!


About Endouble

Even though our mission and vision are very important to us, research has shown that candidates don’t want to read about a company’s vision and mission in a vacancy text. If you decide this role is for you, you can get to know us a little better by checking out our website: endouble.com!

Dit ga je doen:

The role

You will work in an Agile team of 4 devs and a PO. We follow all the Scrum ceremonies, so the day starts with a daily stand-up meeting in which you discuss the work that you did, the tasks you will work on that day and any problems you might have encountered the day before.

As our new Medior Front-end Developer you will:

  • Work with React to create websites with the Endouble Career Site Builder (CSB) framework
  • Create components that can be reused and distributed to other teams within the company.

  • Working knowledge of and proficiency in JS (Specifically: ES6)
  • The ability to write tests
  • Knowledge of how Git works and ability to use it (preferably through CLI)
  • Basic understanding of what accessibility (WCAG) is, what the common pitfalls are and how to implement it properly
  • Working knowledge of performance and ways to optimise
  • General understanding of bundlers (preferably Webpack) and task runners

Your personality:

  • You keep an eye open for new technologies and opportunities to use them.
  • You constantly want to improve your work (and that of others).
  • You actively keep your knowledge up-to-date.
  • You like wearing suits? You’re kidding, right?!
  • You’re the smart type who asks the right questions, not the "been there, seen it, done it" type.

  • A salary between €3000 and €4000
  • An education budget of 4% of your yearly salary.
  • Thorough peer reviews to improve your hard and soft skills.
