Mendix – the leading low-code application development platform:
The Mendix Platform uses visual modeling to abstract long-form coding out of application development. Our customers use Mendix to create and deploy better software for the enterprise, faster. Mendix enables collaboration between business users and developers to work together throughout the development process.
Read our Customer Stories to learn more about the wealth of software and solutions global organizations have built with the Platform.
At Mendix we strive to maintain a diverse, open, and safe working environment where people can be their true selves. We value every voice, celebrate individuality, and appreciate the diversity of thought and experience. People who work here are driven, smart, and really good at what they do.
As this market evolves, we encourage people of all skill levels to work with the platform, both for clients and candidates. Apply today to discover how you can make a meaningful impact with Mendix.
As our product grows and evolves, we continuously decide which features end up in the platform itself, and which features end up as content (widgets, modules). To ensure sustainable growth, it is essential to have a core that is lean and highly extensible. This strategy enables us to serve an ever-growing range of platforms, channels, and use cases with our product.
Software development and delivery is a true team effort where testing is done by everyone involved. However, to drive the overall quality and continuous improvement of the product, we are looking for a test engineer that can take this to the next level and oversee it for the entire team.
We are looking for an expert to proactively set up a test strategy and process informed by a risk analysis to determine what and when to test. We expect you to drive this forward by building automated tests, writing useful scripts, analyzing customer journeys, creating test reports, and investigating incoming support tickets.
In this role, you will join a team that focuses on delivering high-quality, high-value capabilities and solutions on top of the core platform. You will carefully determine if and how existing platform functionality can be transformed into 'content' (e.g. widgets, modules, extensions), to keep the core lean. In addition, you and the rest of the team will create additional content (mostly in the form of modules) to deliver essential functionality to our users. The most recent example of this is the PDF Document Generation module/service.
The team is positioned within the unit responsible for Studio Pro and the Runtime. It is uniquely positioned to enhance the platform capabilities, while working in the heart of R&D.
