Generative AI Engineer

Senior AI Engineer: Your Next Step Up (Belgium, Permanent)

Ready to move from building AI to leading it?

La Fosse is partnering with a respected Belgian data and AI consultancy to find a (Senior) AI Engineer who wants more ownership, more influence and a real path to leadership. Here, AI is never hype. It's used to solve real business problems for leading organisations across multiple industries.

Why this role stands out

• Real ownership. You'll shape solutions from the first client meeting to production, and your technical calls will count.
• Variety. Every client is a new problem. Some need GenAI, others need classical ML or statistics, and you'll help decide which.
• Room to grow. You'll mentor talented engineers, join presales as the trusted technical voice, and follow a clear route to a Lead or Expert role.
• A culture that shares. Tech talks, pairing and people who care about doing things properly.

What you'll do

• Turn client challenges into practical AI solutions, from quick MVPs to secure, production-grade applications
• Build end-to-end pipelines with proper evaluation, guardrails and monitoring
• Coach junior colleagues and help set technical standards

What you'll bring

• 4–7 years as an AI/ML Engineer with production experience
• At least one AI solution taken from POC to production
• Strong Python and SQL, plus solid software engineering habits
• Hands-on GenAI experience (RAG, agents, vector databases or LangChain/LlamaIndex), plus classical ML skills
• Cloud experience (Azure, AWS or GCP) and Docker
• Consultancy or client-facing experience
• Some mentoring experience, even informal, and the ambition to do more
• Fluent Dutch and English
