Responsibilities

As a backend developer, you are responsible for designing, developing and maintaining the software of digital channels. Together with the business and your scrum team, you develop API’s and functionalities that meet the end user’s needs. You have a strong technical background and can advise on the ideal solution for the stated problem. You are capable of explaining to non-technical colleagues the impact of the technical choices. 

You believe that contributing to a good atmosphere is essential for a successful, respectful and welcoming workplace. You enjoy helping and coaching less experienced colleagues.

Together with your team, you are responsible for the concept, development and deployment of the product as well as maintaining the underlying infrastructure. We ship early, often, and quickly. To do this, we use continuous delivery and trunk-based development, and a Kubernetes platform running docker containers. In our development process, we have a strong focus on quality and security that is reflected in our way of working. Strong teamwork is important, but you have to be able to take independent decisions as well.  

As a senior developer joining our team, you are passionate about programming, dev/ops, and finding digital solutions for complex problems. You have strong communication skills, are open to other people’s opinions, and you like to work closely with other disciplines to achieve the best results. Additionally, you can weigh up short term against long term solutions, being able to prioritize. 

You show ability to translate technique to non-technical people and you are critical on your own work and that of others. Mentoring less experienced team members comes naturally to you. Being able to think outside the box, you dare to experiment, show initiative and take responsibility.
