Junior Forward Deployed Engineer - GenAI

About the role

Sia, a global management consulting group founded in 1999, is hiring a Junior Forward Deployed Engineer in Luxembourg. The role bridges the gap between GenAI demos and production: you build GenAI applications (agents, RAG pipelines, copilots) and help them get adopted in daily workflows. You work closely with a senior Forward Deployed Engineer on client sites, at the intersection of data science, ML/platform engineering and client delivery.

Key responsibilities

• Learn how client teams work and where AI can help, alongside a senior colleague.
• Help scope and build LLM-based solutions: RAG pipelines, tool-using agents, workflow automation and chat interfaces.
• Connect solutions to existing systems (APIs, databases, business tools) using established patterns and templates.
• Apply data protection and AI regulation requirements (GDPR, EU AI Act, model licences).
• Support user adoption: prepare documentation, contribute to training and collect feedback.
• Measure solution performance in use and share progress in written and verbal updates to technical and business audiences.

Required profile

• Master's degree in computer science, AI or a related technical field; projects matter as much as the degree.
• 0 to 2 years of experience, including internships or research; recent graduates with LLM projects are encouraged to apply.
• Has built with LLMs (prompting, RAG, basic agent workflows, simple evaluations).
• Willingness to learn the client's stack and to explain technical ideas to non-technical people.
• French and English; German is a strong advantage.

Required skills

• Python, with clean, readable code.
• Calling APIs and connecting systems.
• Bonus: applied AI frameworks (LangChain, LlamaIndex, OpenAI SDK, Anthropic SDK), cloud deployment (AWS, Azure, GCP), MLOps/LLMOps basics, vector databases and embeddings.

What we offer

• Competitive salary and benefits, including hospital insurance and a performance-related bonus.
• Learning budget, funded partner certifications (Anthropic, AWS, Databricks) and paid conference time.
• Hybrid work from the Luxembourg office.
• A named mentor from day one and a path to lead engineer or client-facing architect.
