Description

Sibelga is strengthening its Energy Transition team of about 15 employees within Digital Business Solutions. The team manages applications that support the energy transition, including customer access to energy consumption and the management of energy communities. It also supports applications used to manage customers in vulnerable situations. The application landscape includes a digital data hub, an ERP system, and mobile and web applications connected through web services.

The IT Functional & Test Analyst participates in the evolution of these applications by analysing business needs and translating them into functional solutions. The consultant facilitates discussions and workshops, aligns possible solutions with the end-to-end IT architecture, and validates them with the business. The role acts as an intermediary between business stakeholders and development partners. Functional designs and analyses are documented using the applicable methods and tools.

Testing and operational quality are central to the assignment. The consultant coordinates, develops and executes test plans, controls development deliverables, and follows identified bugs through resolution. The role also shares responsibility for application management with developers and provides second-line support for incidents and problems. The assignment runs at a 100% work regime with hybrid homeworking and a minimum of three days per week on site in Brussels.
