Function

Elia Group operates at the heart of the European electricity system as a critical infrastructure operator in Belgium and Germany. The ongoing energy transition and digital acceleration are transforming our technology landscape, blurring the traditional boundaries between OT and IT. Cloud platforms, real‑time data, advanced analytics and modern infrastructure technologies are central to how we operate safely and efficiently while meeting the highest standards for reliability, security and regulatory compliance.

IT Technology Architect

As IT Technology Architect, you are accountable for the technology architecture, technology standards coherence, and architecture documentation of complex projects and initiatives spanning multiple IT domains. You are engaged from the earliest stages of initiatives to guide architectural decisions, consolidate existing technology standards and ensure alignment with enterprise architecture principles and target architecture.

• Advise IT management, solution architects and business stakeholders on complex technology decisions and support change through clear communication, documentation and guidance

Your Profile

• Master’s degree in computer science, engineering or equivalent experience
• Minimum of 5–8 years of experience in technology, infrastructure or solution architecture roles in complex IT environments
• Strong experience in cross‑domain IT architecture (infrastructure, cloud, data, security, platforms)
• Ability to apply architecture management frameworks such as TOGAF and IT service principles such as ITIL
• Experience producing and maintaining architecture deliverables across levels (principles, standards, target and solution architecture)
• Solid understanding of security-by-design and compliance constraints in regulated or critical environments
• Solid understanding of modern IT and platform technologies
• Experience with regulated or critical environments is a strong asset
• Strong analytical, communication and stakeholder management skills
• Pragmatic mindset, balancing architectural ambition with operational realities
• Ability to influence without formal authority and to facilitate consensus across teams
• Fluent in English; knowledge of French, Dutch or German is a plus
