Résumé du poste

Elia Group is seeking a Data Integration Engineer in the Brussels area to own and evolve our external data exchange platforms. You will work within the Data Chapter to build reliable, scalable data flows with external parties, balancing operational stability with long-term improvements.

You will collaborate with product stakeholders and architects, communicate clearly during incidents, and contribute to a resilient data integration landscape that supports Elia Belgium and regional energy markets.

Qualifications

• Strong experience with data integration technologies, including messaging, file-based exchanges, APIs, data transformation, validation, and monitoring.
• Experience with external data exchanges involving parties is an advantage.
• Proactive, structured, and autonomous work style with ability to collaborate.
• Excellent communication with technical and non-technical stakeholders.
• Ability to document decisions and share knowledge to improve resilience.

Responsabilités

• Make architectural decisions, document and defend them
• Ensure the stability, maintainability, and evolution of the data integration technologies in your scope, including the platforms supporting data exchanges with external parties
• Understand and manage end-to-end external data exchanges, including interfaces, data flows, dependencies, operational constraints, and expectations from internal and external stakeholders
• Investigate complex technical and operational issues, support incident resolution, identify root causes, recommend solutions, and help prevent recurring problems
• Identify technical debt, operational risks, and improvement opportunities proactively, anticipating future needs and proposing where modernization or investment is required
• Define and maintain the roadmap for your integration capabilities, balancing short-term operational stability with longer-term technical improvements and strategic objectives
• Provide clear technical input into prioritisation and investment decisions, through roadmaps, technical assessments, risk evaluations, recommendations, and planning information
• Communicate effectively during incidents and periods of uncertainty, providing a clear view of impact, known facts, ongoing investigations, actions, risks, and responsibilities
• Work closely with the Product Owner and other stakeholders, bringing the technical perspective into prioritisation discussions, making constraints and risks visible, and translating business needs into realistic technical choices
• Collaborate with architects and the chapter, aligning your solutions with wider integration and data architecture, common engineering practices, technical quality standards, and ways of working while bridging target architecture with operational reality
• Build resilience around the domain by documenting and sharing knowledge, collaborating with colleagues, clarifying decisions and ownership, and progressively reducing unnecessary dependency on individual experts
