Agile Collaboration: Actively participate in Agile/Scrum sprints, translating ambitious business requirements into production-ready AI solutions.

Your Profile

Experience Requirements:

Junior (J): 1+ year of experience working on NLP, chatbot development, or initial LLM projects.
Medior (M): 3+ years of proven experience building and deploying generative AI pipelines, RAG systems, and integrations in production.

GenAI & LLM Stack: LangChain, Python, Prompt Engineering, RAG frameworks, Vector Stores.
NLP & Conversational Platforms: Natural Language Processing, Botpress, Rasa, or similar conversational design tooling.
Engineering & Deployment: Full-stack development skills (Frontend & Backend), DevOps practices, CI/CD pipelines.
Security & Governance: AI Security controls, GDPR compliance, data anonymization.
Frameworks: Agile/Scrum methodologies.

Language Skills:

Fluent in either Dutch (NL) or French (FR) (Minimum 3/4 - Professional Working Proficiency)
AND Fluent in English (EN) (Minimum 3/4 - Professional Working Proficiency)
