Senior AI Architect

We are seeking a highly experienced German-speaking Senior AI Architect for a long-term public - sector project in Germany. We're looking for an architect with a deep technical foundation in modern AI systems : someone who has led the architecture of multiple GenAI solutions and understands LLMs not just conceptually, but from the inside, including fine-tuning and productive deployment.
