As a Senior Frontend Developer you will be an addition to a senior and highly skilled team of 6 senior software engineers (with different focus areas). Everybody in the team is working on multiple tasks and takes writing great code seriously, from requirement analysis to production. 

What you’ll do:

As our Senior Frontend Developer you will design, build and enhance complex web applications (external and internal), linked to massive data streams. With the high growth of assets, you’ll encounter a great challenge to keep the interaction in a clear and intuitive manner. Of course you will build with scale & reliability in mind.

Next to this there will be an opportunity to work on a brand new application for our service partners. Users of all our applications are technically qualified, so it doesn’t need to be ‘1 button’ all the time 😉
