Senior🎓
Top SchoolJérôme Belleman is a seasoned IT leader and computer engineer with 14 years of experience designing, operating and improving large-scale IT services for high-profile organisations such as CERN and the International Telecommunication Union. As Head of IT Support & Operations at ITU’s Telecommunication Standardisation Bureau, he blends hands-on engineering—automation, monitoring and testing frameworks—with people-focused process improvements and succession planning. His background spans migration of legacy desktop systems to modern web stacks, CI/CD and behaviour-driven testing at scale, and managing configuration and batch systems across thousands of nodes. At CERN he led cost-saving platform migrations and created integration/testing systems that became foundational to operations, demonstrating a pragmatic focus on reliability and efficiency. Fluent in four languages and actively developing leadership and communication skills, he pairs technical depth with a knack for cross-team collaboration and clear documentation. Notably, he has repeatedly turned ad-hoc monitoring and legacy tooling into scalable, auditable solutions that serve international stakeholders.
