About the Mission

IT operator of the Wallonia-Brussels Federation. As a public-interest body it designs, develops, maintains and evolves the information systems and technology infrastructure serving the administrations and institutions of the Federation. A central player in the digital transformation of the French-speaking Belgian public sector, it works on IT infrastructure (networks, security, data centres, cloud), custom business applications, digital project support (functional analysis, UX/UI, project management), cybersecurity and data protection, and user support and training.

As part of the ZEPHYR programme of the Office de la Naissance et de l’Enfance (ONE), we are looking for a Technical Scrum Master / Developer to guide a development team in applying Agile practices, backed by hands-on software development experience in Java / Angular environments. The role is primarily Scrum Master, with the ability to step into technical topics when needed.

The Technical Scrum Master ensures the team runs smoothly, facilitates the Scrum ceremonies and removes impediments. They also make sure technical constraints, dependencies, risks and software quality are properly reflected in planning and follow-up. They work closely with the Scrum team (developers, functional analysts, testers, Technical Lead, Product Owner), project managers and other stakeholders.
