You can break down technical concepts for diverse audiences in English and ideally in German as well. Supportive. You coach junior team members, provide constructive feedback, and actively contribute to our culture of learning.   Profile: Degree in computer science, AI, data science or similar field. Experience: 3+ years of experience in machine learning or AI engineering, with hands-on AI projects in production. Proficiency in Python and cloud-based AI services (GCP, AWS, or Azure). Solid understanding of data analysis/engineering and AI-specific components like RAG, prompt design, fine-tuning, embeddings, and model evaluation.
