Senior Fullstack Developer (m/f/d)

T-Systems is part of the Deutsche Telekom Group, with around 30.000 employees worldwide. We create technology with purpose to generate a positive impact on society. We are looking for curious talent, eager to learn, take on challenges, and contribute ideas that transform our customers’ experience.

We trust people: we offer autonomy, continuous support, and a collaborative environment where you can grow without limits. We are one global team, guided by respect, integrity, and a passion for doing better every day.

We are looking to staff a small, internal team for the development, integration and operation of new services to support mobile planning processes. Three projects are currently underway in this area, namely PreHCM NewMobile, FNP Cockpit and freiHEIGHT, in which IT solution designs have already been created and requirements specified, which are now to be implemented.

1. PreHCM NewMobile is the replacement of an existing, monolithic application in which parameter registrations for mobile radio sites at the Federal Network Agency were previously coordinated by e-mail and are now to run automatically via M2M interfaces.

2. FNP Cockpit is currently a PowerBI solution whose current architecture and data provision are problematic and is therefore to be completely rewritten in a service-orientated way to fit better into the environment.

3. freiHEIGHT is currently a Matlab application that helps to analyse security reserves at mobile radio sites. This is also to be completely rewritten in a service-orientated way and integrated into the processes.
