Job profile

We are looking for a dynamic individual with at least 4 years of demonstrable experience as a Senior front end web developer and a higher professional education level.

We are looking for someone who is ambitious, professional and can thrive in a challenging environment.

In addition, we are looking for someone who wants to develop himself or herself further and is enthusiastic about expanding and sharing his/her knowledge. You are someone who has insight and analytical skills and is able to oversee an application in the larger picture. Above all, you have to be someone who has both feet on the ground and has a pragmatic approach. You have to have a service-oriented attitude, both to customers and to your colleagues. We also ask for a proactive attitude towards improving our products.

A nice aspect of the vacancy is that you occasionally have the opportunity to visit abroad. This can be an international destination and you will go with a colleague consultant and hardware engineer to a customer to test on location and deliver a project. This involves a short stay of 1 to 2 weeks and will always be in good consultation. Since a lot of communication is in English, you are expected to have a good level of English in word and writing.

Your main task will be to design and implement a greenfield user web interface for our PASS application. We expect you to be able to make recommendations for framework choices. The writing of technical design documents will fall under your tasks too.

It is a web application that will run on-premise for our current customers from security and performance considerations. The technical design of this user interface will have to take into account the security considerations that belong to a cloud-based SaaS / PaaS solution so that we can offer a cloud-based solution. To be able to fill this user interface with data, the developer in combination with the backend developers will also design the backend api's for this UI.
