Side‑by‑side with your talented colleagues, you will play a part in building a sustainable, green and reliable energy infrastructure that stimulates economic growth and reduces our ecological footprint.

Only together can we make the biggest impact possible! We believe in the power of diversity – an inclusive and diverse work environment leads to more innovation, creativity and better results.

Enterprise Infrastructure Architect

Requisition ID: 10905

Posting Start Date: 27/04/2026

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.

To support this transformation in a controlled and sustainable way, Elia Transmission Belgium is strengthening its transversal technology architecture capability and is looking for an IT Technology Architect to shape, govern and align technology choices across IT domains.

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. You act as the integrator of technology architecture, coordinating domain architects and experts rather than producing architecture in isolation, and you formally represent IT Technology in governance bodies, including the Architecture Review Board.

Key Responsibilities

• Define and govern end-to-end technology architectures for transversal IT initiatives
• Translate business needs into clear, scalable and secure technology solutions
• Consolidate, maintain and promote IT technology standards and reference architectures across infrastructure domains (network, server/compute, cloud, end‑user devices & associated platform and security constraints)
• Coordinate architectural input from multiple domain teams and ensure consistency
• Maintain high-quality architecture documentation (principles, standards, target and solution architectures)
• Represent IT Technology in governance bodies, including Architecture Review Boards
• Embed security, resilience and regulatory compliance by design
• Contribute to target architecture evolution, roadmaps and standardisation initiatives
• 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

Offer

• Competitive salary package, allowance for representation expenses, year‑end bonus, double vacation pay, meal vouchers (€10 per working day), eco‑vouchers, sport & culture vouchers, bonuses based on individual and group results
• Group insurance, hospitalisation insurance, ambulant care insurance for the whole family and personal accident insurance
• Vacation: 20 days plus 5 additional days, 6 local days, 4 exempt days (after 1 year of employment) and up to 5 long‑service days (1 day for every 3 years of employment)
• Social fund: year‑end vouchers, birth and marriage allowance; we also cover part of the cost of glasses, a dental prosthesis or similar needs
• Communication: iPhone, phone subscription (for work and private use) and a laptop with internet reimbursement
• Discounts: 30% discount on gas and electricity bill
• Mobility: company car, public transport or mobility budget
• Shares: opportunity to subscribe to shares with a discount of 16.66% on the average share price

Location

Emperor – close to central station + homeworking. Occasional travel to Berlin, Germany.
