UX Developer C#/WPF

We are looking for a WPF and C# enthusiast that want to build software characterized by top quality and excellent usability. We are developing health care oncology systems used in hospitals all over the world by doctors, nurses and physicists to treat cancer patients. Our organisation is expanding, and we need someone who loves improving GUI and interaction design. Someone who cares for how software look and feel and for the users. 

About the role 

As a C#/WPF developer in the UX team you will join our mission to create systems providing excellent usability and an outstanding user experience. You will support the development organisation with your WPF design skills. With other developers you share knowledge, do pair programming, provide best practice, do code reviews and trainings. In the UX team, you work close to UX designers and Visual designer to finetune existing UIs in existing products as well as creating new reusable UI components and sometimes new applications. 

Your responsibilities will be to: 

  • Support an agile software development environment building medical device classified software

Your profile 

You have an eye for details, love quality and do your very best to provide our users with the most effective, efficient, and easy to use software so that they can focus on treating cancer patients, not on how to use the software. 

You are very knowledgeable in creating a good looking and well behaving product and you like sharing that knowledge with others to together achieve the very best result. You are a team player but can take your own initiatives and responsibility for your work and deliveries.
