AI/ ML Engineer

Permanent employee, Full-time · Hamburg & Remote

Das machst du bei uns:

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

Das bringst du mit:

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.

Bonus Skills
Nice-to-have, but not deal-breakers — if you’re eager to learn, we’ll support you:

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

You live in or around Hamburg and enjoy working regularly in the office
