Mendix is a visual, model based IDE to create web apps. Our team is responsible for editing the pages in the (Web) Modeler and visualizing them on all browsers / devices.

Why we like it here:

  • We’re building something new, making stuff up as we go along.
  • We’re working on a platform and we’re in it for the long haul. Thousands of developers and end users across the globe rely on your work and each commit could make them all very happy (or incredibly sad).
  • We’re stubborn and like to get to the bottom of things; clear answers are more important than deadlines.
  • We dabble in all sorts of technologies when it takes our fancy. Although we focus on JavaScript / Typescript & C# we often branch out into HTML5, CSS3, Scala / Java. Other libraries we use include React, Webpack, Node, Jasmine & Karma.

You could be our new team member if:

  • You’re fluent in JavaScript and its functional style. You’re a polyglot.
  • You’re interested in usability.
  • You don’t like using jQuery, but figuring out how it works.
  • You want to become part of a work environment in which your ideas are valued.
  • You’re comfortable working as part of a scrum team.
  • You enjoy the occasional game of foosball and / or ping pong.


We're a company that creates software to create software. We started off building a modeling environment (let's say ruby-on-rails meets visio). Since then we’ve evolved to support the entire software development lifecycle; everything from creating software to automatic deployments to ticketing, we offer it all. This brings on a ton of cool challenges: we get to tackle all of the fundamental CS problems and solve them in new and cool ways.

We're all open for using the latest tech, as long as it's a good match. Every other month, we have research days where devs are invited to work on whatever they want. People work on things such as that one bug that somehow never got prioritized or building a lego mindstorms setup to control the elevator.

We like people that take ownership and try to give everyone as much freedom as possible. That means as little process as we can get away with: we don't want to get in your way. We also strive to stay as flat as possible: have an issue? Walk right into our CTO's office and bring it up. Despite the fact that our client base consists of large enterprises, we do not allow an enterprise culture to enter our R&D department. We value our start-up culture which has brought us so much success. We are a tech company, not a consultancy firm.
