Primary Role & Responsibility

As a senior software engineer, your daily work involves technically challenging applications and projects where your code makes a direct contribution to the further development and upkeep of our VI solutions and to its application in projects.

As a software engineer, we expect much more from you than just the ability to design and develop good software. We find it important that you possess an inherent drive to get the best out of yourself every day, that you are inquisitive and that you are not intimidated by situations which require you to branch off from the beaten track. You work together with colleagues in a SCRUM team. In addition, you have regular contact with other software teams, software architects, testers and end users. Good communication skills are therefore extremely important, as well as the ability to think pro-actively and suggest possible improvements. This gives you every opportunity to contribute your personal input and grow and develop within the department.

The often-complex functionality of the software includes business logic, controls for logistical transport, communication with external computer systems, reporting, data analysis and simulation. This functionality is spread across the various components of the VIBES suite. You design, program and test the software based on a design concept and a set of requirements. In some cases, you must personally formulate these requirements together with the (end) users and / or internal stakeholders. Learn more about the VI products.
