About the Position

AI Engineer

Brussels/Flanders, Belgium

Sopra Steria offers tailored, end-to-end corporate technology and software solutions to help clients make bold choices and deliver results. With more than 51,000 colleagues in nearly 30 countries, we rank as Europe’s leading digital solutions provider. Some of the most successful companies in Europe rely on our technology due to our commitment to innovation, collaboration, and value in business development.

The world is how we shape it. Let’s shape it together.

Join our Data & AI team.

You will become part of a multidisciplinary team where data engineering, architecture, AI, analytics, governance, and visualization come together. Together, we help clients get more value out of their data: from setting up the right data foundations to building dashboards, analytics solutions, and AI use cases that support better decisions.

As an AI Engineer, you will contribute to this by designing, building, and industrializing AI solutions that solve concrete business problems and can be used in real operational environments.

You bring traditional AI and generative AI into real-world use cases by helping our clients design, build, and deploy AI solutions. You work on solutions ranging from machine learning models and NLP to LLMs, semantic search, RAG solutions, and conversational AI.

You train, fine-tune, improve, and deploy ML and AI models. You write production-ready Python code to serve online, batch, and real-time models, and you build applications and software components that make AI-driven use cases usable in practice.

You work in close collaboration with Data Scientists, MLOps Engineers, Data Engineers, AI Architects, and other specialists to integrate all parts of the solution. Depending on the project, you may help build new AI solutions from the ground up or support clients in operating and improving existing solutions over a medium to long-term basis.

Within our Data & AI team, we help each other grow and keep learning from one another. Are you looking for a role where you can combine AI engineering, software development, MLOps, and applied innovation? Then the Data & AI team at Sopra Steria is the right place for you.
