You’ll be the driving force behind a production-ready, fully asynchronous FastAPI-based RAG (Retrieval-Augmented Generation) system that powers personalized e-learning experiences.This role is perfect for someone who loves to design AI architecture and get their hands dirty building and deploying it — taking things from idea to “running on the big machine.”You’ll own the full lifecycle: from architecture and implementation to deployment, monitoring, and continuous improvement.Expect to work closely with product and engineering teams where research meets production — building things that actually ship, scale, and make a difference.What you’ll do

• Develop and maintain a fully asynchronous FastAPI backend for AI services
• Build and scale a RAG pipeline using Qdrant (vector search) and PostgreSQL (metadata)
• Design modular, scalable NLP and LLM architectures — from embedding pipelines to agent orchestration
• Create APIs that connect frontends with AI systems and make data flow seamlessly
• Deploy and monitor using Docker, Kubernetes, Prometheus, and Grafana
• Collaborate across teams to translate ideas into reliable, high-performing systems

You bring both architectural understanding and hands-on coding energy.You’re reliable, detail-oriented, and curious — someone who enjoys making complex systems work smoothly in the real world.What you bring

• Strong Python skills, especially with FastAPI and async development
• Solid understanding of RAG systems, vector databases (like Qdrant), and NLP pipelines
• Experience with PostgreSQL, Docker, and basic deployment workflows
• Familiarity with AWS S3 operations and ETL/text data processing
• Ownership mindset — you care about reliability, performance, and clean delivery
• Clear communication and a collaborative, team spirit attitude
• You communicate fluently in English and also feel confident in German.

• Knowledge graphs (e.g. Neo4j) and graph databases
• Monitoring and observability with Prometheus and Grafana
• Kubernetes-based deplyoments and GitLab CI/CD workflows
• Understanding of multi-agent orchestration or reranking strategies
