Job Description

What we are looking for

We have developed a research tool that meters online behavior on computers, phones and tablets in a privacy conscious way. We are currently active in over twenty countries, across 5 continents, and have approximately 100,000 research participants active with our software on a daily basis.

As JavaScript is embedded in many parts of our technology, we need a skilled JavaScript developer that can architect and manage this part of our technology.

The primary focus of the position is building and maintaining our browser extensions. We are looking for somebody that is experienced in JavaScript, has experience with (or an interest and eagerness to learn) browser extension development and can take what we have to the next level.

What we offer

Our team is a group of passionate all-round engineers. The development method we use can be described as pragmatic and efficient. We all hang out on Slack and have daily face-to-face meetings. And of course, don't forget the Friday (and sometimes Thursday) afternoon drinks.

We offer you not only a challenging and stimulating professional project, but also a competitive compensation package. We will also kit you out with a 27" monitor and a laptop of your choosing.

Skills and experience

  • You are a team player and fun to work with
  • Proficient in JavaScript (ES6)
  • Experience with Node.js based testing frameworks and build tools
  • Experience with, or willingness to learn, browser extension development
  • Proficient in Git
  • English language proficiency
  • Experience with Docker and Amazon Web Services is a plus, but not required
