Senior Machine Learning Engineer

Function

The Senior Machine Learning engineer is the technical reference for the EL.AI product, the Central IT AI platform that eases the lifecycle of Machine Learning and AI models — from build, to training, to deployment and monitoring.

The role turns emerging AI capabilities into production-grade, reusable platform features that accelerate the enablement, adoption and security of AI across Elia Group. Working hand in hand with the AI Architect and the Product Owner, the senior machine learning engineer owns the “how”: technical feasibility, implementation patterns, operationalization and engineering quality of the platform.

The role is deliberately hands-on and enablement-oriented. It is the execution counterpart of the AI Architect, who owns the target architecture, standards and governance framework.

Responsibilities

• Shape the technical roadmap of EL.AI by evaluating emerging AI capabilities and translating them into scalable, production-ready platform features.
• Drive the design, development and continuous evolution of the EL.AI platform, with a strong focus on scalability, reliability, maintainability and operational excellence.
• Develop reusable frameworks, templates, pipelines and reference implementations that accelerate the adoption of AI solutions across the organization.
• Translate architectural principles into concrete implementation patterns and contribute to the continuous refinement of architectural decisions through operational and implementation feedback.
• Contribute to the evolution of AI governance by turning implementation experience into actionable standards, guidelines and best practices.
• Ensure seamless integration of the platform within the broader AI, data and IT landscape of the Group, while maintaining close alignment with relevant stakeholder teams.
• Conduct technical evaluations, prototypes and proof-of-concepts to validate new technologies, assess feasibility and reduce implementation risks.
• Safeguard technical consistency across the platform and actively contribute to reducing technical debt and improving the long-term sustainability of solutions.
• Act as a technical reference within the team by fostering engineering excellence and promoting best practices in software development, MLOps, CI/CD, testing, observability and documentation.
• Support product development and platform adoption through technical feasibility assessments, onboarding activities, operational guidance and the translation of relevant AI market developments into concrete recommendations for the product roadmap.
