Woerden & Gdansk


As a senior front-end developer, you will have a very flexible role. You will be responsible to help our development teams (mainly back-end focused) to make the right decisions and create the best code when it comes to front-end. This can be for a specific customer implementation where you build the complete login flow or rebuild the front-end in such a way that customers can adjust their own styling. But it can also be working on the user interface of our own applications. For our applications we are going to set up a design system with reusable components. 

Within this role you are not part of a specific team, but you will switch teams depending on the work to be done. As the lead front-end developer, you will have to come up with the best plan of approach and a planning for most of the work. You will also explain your chosen approach to the rest of the team. In knowledge sharing sessions you will inspire the other developers to improve their front-end skills.  


You are a senior experienced (>5 years) Front-end Developer who relishes the challenge of building and improving all front-end solutions related to applications for secure authentication. Your solutions are secure, responsive, and accessible. You can quickly master new technologies, have the desire to continually improve, can respond to our current customers’ requests, and can cooperate with a team to build something out of nothing. You are results-oriented with an appetite for hard work but also enjoy your work!
