GenAI Trainee

Euronext is the leading pan-European market infrastructure, connecting local economies to global capital markets. Within the COO scope, the AI Team identifies, prioritizes and delivers innovative AI solutions that drive business value across the organization — from conversational agents to document intelligence, from browsing automation to agentic orchestration.

About the AI Trainee Program

This is a 12-month development program with hands-on experience across the full AI lifecycle. You will join a structured program that includes:

• 1-week centralized onboarding on enterprise AI tools, platforms, governance and responsible AI
• 2–3 real use cases end-to-end, from proof of concept to production deployment
• Two international trips to other Euronext locations (e.g. Paris, Milan, Athens) for cross-team collaboration on real business projects
• Buddy assignment and continuous mentoring from senior AI developers, MLOps and data professionals
• Training on cutting-edge AI tools — you will regularly test and get hands-on experience with the latest AI technologies, frameworks and platforms as they emerge
• Meal allowance, business travel opportunities, and 24 company holidays per year

What You Will Work On

You will contribute to production-grade Generative AI solutions that serve real business teams across Europe. Examples include:

• Building and improving AI agents that autonomously browse websites, extract data and validate regulatory information
• Developing RAG-based chatbots and conversational assistants for internal and external users
• Creating document intelligence pipelines that parse, classify and extract structured data from complex financial documents
• Integrating AI capabilities via REST APIs, MCP servers and agentic orchestration frameworks
• Supporting monitoring, testing and troubleshooting of AI solutions in production
• Collaborating with business stakeholders to gather requirements, iterate on solutions and deliver training

What We're Looking For

• Bachelor's or Master's degree (completed or in final year) in Computer Science, Engineering, Data Science or a related field
• Solid knowledge of Python and software development best practices
• Familiarity with Git and collaborative development workflows
• Understanding of machine learning, deep learning and generative AI concepts
• Interest in LLMs, RAG, prompt engineering and AI agents
• Awareness of RESTful APIs, at least from a user's perspective
• Nice to have: exposure to cloud services (AWS or Azure), FastAPI, or frontend development
• Excellent problem-solving skills and a hands-on, execution-oriented mindset
• Fluency in English and Portuguese, both written and spoken
• A collaborative attitude with genuine curiosity for emerging AI technologies

Why Euronext

You will join a global AI team working at the frontier of enterprise Generative AI — building agents, orchestrating tools, and deploying solutions that operate at scale in regulated financial markets. This is not a theoretical internship: you will ship code to production, interact with business users across Europe, and gain experience with technologies that define the future of AI engineering.
