Role Description

As a Senior Back-End Java Developer, you will build robust, high-performing, and scalable solutions with a focus on customer experience. You will ensure high code quality and support the team in delivering solutions on time and within budget.

Business Objective

4 years ago, Proximus initiated a strategic OSS transformation program to modernize the provisioning of telecom services for its customers. Central to this initiative is the implementation of the Network Service Abstraction Layer (NSAL), aligned with the Telecommunications & Media Forum (TMF) standards. This layer facilitates the provisioning of both services and the customer-premises equipment (CPE) required for activation.

As part of this transformation, a major project was launched to replace the legacy CPE management system. The first phase has been successfully completed with the deployment of a new CPE management platform. The next phase will focus on redesigning the IT system that interfaces with this platform.

To support this evolution, the project team has been strengthened with four new team members. This initiative contributes to the broader goal of implementing a TMF-compliant system for managing CPE resources, in line with the company's digital transformation strategy.

The selected candidate will join the CPE Management squad, composed of six members within the Network Activation and Automation tribe. This Tribe is responsible for provisioning various telecom services (VOIP, internet, TV, etc.) and is driving an ambitious project to transform and digitize the provisioning system.
