Web Developer (part time)

Are you a driven Web Developer looking for a nice part time challenge? Come and work at Coosto!

What will you be doing?

Coosto provides software solutions for social media monitoring and web care. We process millions of social media messages every day (from Twitter, Facebook, LinkedIn, to news sites, blogs and fora) and make these available in our search engine, which can be used by hundreds of our customers at the same time. The teams at our Data Division are responsible for collecting and processing these messages, and we do that by means of several software systems and scripts. For this department we are looking for a part time Web Developer.

You will join a team of three part time web developers, and work close together with the other teams at our Data Division. In this role you will be working on the entire chain of web development; from designing a database to writing server code and programming the frontend. The focus of the role is on the latter, but you will also be involved in maintaining and migrating existing systems.

The software and associated tooling on which you will be working is mainly used internally, by several teams who work within these environments most of their time. Together with your team you have a great impact on the choices that are to be made. For new, or existing applications, you will conduct research, gather requirements, draw up a plan of action and present this to your stakeholders. Of course you will also develop these applications yourself.

What do you need for that?

You have previous experience with web development and you like to take the next step in your professional career. You love to learn new languages and frameworks; accordingly, you are always up to date with the latest trends and technologies. You are not afraid to ask questions, to be critical on the work of your teammates and to start a good discussion! Besides that, you like good coffee and tea, you are a real Google-fu and StackOverflow is your favorite website.


  • you have experience with frontend development and therefore of course with JavaScript, HTML and CSS;
  • you have experience with JavaScript frameworks, for example Vue.js, React or Angular;
  • you have excellent communication skills in English.

The "nice to haves" are:

  • Experience with visualization frameworks as D3.js;
  • Experience with Unit Testing;
  • Experience with backend development;
  • Knowledge of MySQL and database design;
  • Able to work on the commandline;
  • Experience with Docker and/or Kubernetes;
  • Knowledge of security.

What do we have to offer?

You will come to work in a stimulating environment, full of technical challenges in a team of cool and clever colleagues. We have a strong focus on the Agile way of working. Correspondingly, we work in short sprints, and go live faster every time with Continuous Delivery and Test Automation.

We pay close attention to the further development of your talent; we have a training budget with which you can follow relevant courses and training. Besides that, we also offer you the possibility to go to tech events like Software Circus, JAX DevOps and Code Motion. You will work in a beautiful office in Eindhoven, right beside the train station, with a wide view on the dynamics of the city. Of course, you will get a good salary and an attractive package of benefits.
