The environment you will be working in.

KPN Technium and in particular the MIJN KPN-team is looking for an sr. software engineer. The MijnKPN environment serves both Web and APP (IOS/Android). It supports at least 1,5 MIO customers every month. Working for MijnKPN means making the difference, since there’s no environment with more customer interaction. Soon we will introduce M2M interaction like Siri, Google Assistant as well. In the overall strategy of KPN the MijnKPN APP/Web is explicitly mentioned as the enablers of KPN’s success.

Technical platform you work on

We value optimising processes and applying cutting edge technologies over getting in more developers to achieve scaling.  We are applying this believe to our development process as we want a unified workflow for Web, iOS and Android, hence we are creating a new technical platform/framework with latest technologies as we speak. Apart from this our approach is to shift most business and UI logic to backends and serving a thin frontend to enable flexibility. The frontend is currently based on React-Native and React to interpret the backend and enrich it with platform specific features. Our backend is based on Python. Furthermore we work with Docker, Kubernetes, Pytest, etc.

We take pride in the recent launch of the new MijnKPN App which based on our newly developed framework. We are definitely not finished yet and have enough functional and technical challenges ahead of us. That is where you come in …
