Medior Javascript developer



Amsterdam is looking for an experienced front-end developer with a strong focus on JavaScript.



… think that npm is awesome

Our front-end development stack is completely automated with npm, designed, developed and maintained by the front-end competence and integrated into any back-end build automation tool (e.g. Apache Maven in our Java projects) as a self-contained, independent unit.

This includes
▪Debugging first: source maps for everything
▪On the fly JS linting & transforming with Babel , ESLint, Browserify and optionally JSX
▪Or with webpack if we need HMR
▪On the fly CSS pre- and/or post-processing with Less and PostCSS
▪On the fly building of a front-end pattern portfolio complete with a local preview and LiveReload server and continuous deployment to a public server

… do awesome things during hack-time

Any developer at is entitled to spend 10% of her available time on happily hacking away. We assume developers know what that means. As a matter of fact our aforementioned development stack is an accidental artefact of hack-time, but reverse engineering Exploding Kittens in the browser would be bona fide all the same.

Gevraagd wordt

It’s nice if you know jQuery, but that’s not quite enough. As developers, we only say “JavaScript”, so that HR knows what we are talking about; what we really mean is
▪ECMAScript 2015
▪WHATWG DOM & HTML scripting APIs
▪Node.js & npm
▪React & Redux

… are agile

You should have at least one year of hands-on experience with agile development (e.g. Scrum, Kanban, XP), and actually like working that way. In that time you should also have had some substantial exposure to essential agile practices like test-driven development, continuous integration, refactoring and pair programming.

… haven’t fallen to the dark side (completely (yet))

As much as we like client-side MV* frameworks like AngularJS, or full stack web application frameworks like Meteor, we don’t try to make every project look like a nail. Truth be told, only few of our customers turn out to actually need a nail.

That’s why we are also looking for a JavaScript developer with more than a hammer. In the context of a CMS driven website you should be driven by common sense and a healthy affinity with progressive enhancement. In other words, you haven’t entirely cut the cord with front-end development of yore.

Naast een marktconform salaris met goede secundaire arbeidsvoorwaarden (zoals 30 vakantiedagen en een premievrij pensioen), bieden wij jou een zelfstandige en gevarieerde functie in hartje Amsterdam. Op 10 minuten lopen van Amsterdam CS zijn we gevestigd in een mooi pand op steenworp afstand van de gezellige Nieuwmarkt. Leuke collega’s, vrijmibo’s, hacking days, een kantine met een droomlunch en genoeg vrijheid voor een potje poolen of tafeltennis. Oja, mocht je muzikaal aangelegd zijn, dan kun je je lol nog op in de krochten van de kelder… (discretie van deze muzikale prestaties is niet gegarandeerd, zeker niet tijdens BBQ’s in de tuin)
