Intelvision is looking for an AI Engineer who's passionate about Large Language Models, cutting-edge AI research, and building high-performance conversational systems from scratch.
You'll be joining as the first dedicated AI developer on the project for a client in the e-learning sector — a digitally-forward, all-inclusive boating school delivering top-tier training for the German sport boating license entirely online. The main goal: develop and implement a customer support chatbot capable of automatically creating drafts for the CRM system.
Responsibilities:
— Lead the full AI development cycle: design, train, test, and deploy the customer support chatbot capable of automatically creating CRM drafts
— Train and fine-tune open-weight LLMs such as Mixtral 8x22B, Mistral-Medium 22B, LLaMA 3.3 70B (via Hugging Face)
— Implement supervised training for user-agent conversational models
— Optimize chatbot performance using reinforcement learning and function calling
— Evaluate and benchmark current and emerging LLMs (including testing models like OpenAI's GPT-OSS)
— Collaborate directly with the client and their team to align AI solutions with business needs
— Document processes and model configurations to ensure reproducibility and scalability
Requirements:
— 5+ years of hands-on experience in AI/ML, including Senior, Tech/Team Lead roles
— Proven track record in training and fine-tuning open-weight LLMs for production use
— Deep expertise in LLM architectures, conversational AI, reinforcement learning, and function calling

— Proven ability to run AI projects end-to-end, from PoC to production deployment
— Excellent communication skills with a proactive, consulting-oriented approach
— English proficiency at Upper-Intermediate (B2+) or higher
Would be a plus:
— Passion for LLM research & innovation (you're an "LLM nerd" in the best sense)
— Experience with multiple LLM architectures and model evaluation techniques
— Prior consulting or client-facing experience in AI/ML projects
— Hands-on involvement in benchmarking and experimenting with emerging AI models
— Understanding of deployment best practices for large-scale AI systems
— Familiarity with optimizing inference performance for high-load environments
