Senior Application developer for WOM (Work Order Management) + 5000 Eur Sign on bonus

As a leading digital telecommunications company, we want to meet our customers' basic expectations for personalization, simplicity and a new digital experience. To do this, we are reducing the complexity of our systems and the commissioning of services in the long term and thus implementing the transformation to modern digital platform services. As the gateway for the entire manual service provision of the DTA (Deutsche Telekom Außendienst GmbH), we offer a stable and flexible service assignment for all customer segments (internal and external) and processes (provision, problem solving, infrastructure services).

As the WOM hub, we are responsible for the WMS-TK system (workflow management system for technical customer service), it is one of the central order control systems for technical field service (DTA) and technical service (DTS). The core system based on ARS (BMC Remedy) is primarily used for order entry, coordination and control of all order types in the provision and fault clearance process for the individual and mass market. Due to a high degree of configuration options within the system and the expansion of Java services, the system is constantly growing. The long-term development towards a service-oriented architecture approach with comprehensive use of general REST and API approaches manipulates WMS-TK as a central workforce control component.

You can help us to equip our customer service with IT technology in such a way that business colleagues can assert themselves with more flexibility in the increasingly competitive market and turn customers into fans.
