Python Backend Developer w/ Ai Experience (m/w/d)

Das machst du bei uns:

• You’ll be the driving force behind a production-ready, fully asynchronous FastAPI-based backend RAG system that powers scalable, data-driven e-learning platforms.
• This role is perfect for someone who loves to design  robust backend architectures and get their hands dirty building, scaling, and deploying reliable services — taking systems from idea to stable production.
• You’ll own the full lifecycle: from backend architecture and implementation to deployment, monitoring, and continuous improvement.
• Expect to work closely with product and engineering teams where  solid backend engineering meets selective AI integration, building things that actually ship, scale, and make a difference.

What you’ll do

• Develop and maintain a fully asynchronous FastAPI backend for core product services
• Design, build, and scale  RESTful APIs and backend services that connect frontends, databases, and external systems
• Implement  robust data storage solutions using PostgreSQL and object storage such as AWS S3
• Build and maintain  reliable service architectures for processing, persistence, and data flow
• Containerize, deploy, and monitor services using Docker, Kubernetes, Prometheus, and Grafana
• Integrate AI components (e.g. RAG pipelines, LLM services, vector databases like Qdrant) as part of the overall backend system
• Collaborate across teams to translate product ideas into stable, high-performing backend systems

Das bringst du mit:

You bring both  strong backend architecture skills and hands-on coding energy .
You’re reliable, detail-oriented, and curious, someone who enjoys making complex distributed systems work smoothly in production .

What you bring

• Strong Python backend skills , especially with FastAPI and async development
• Solid understanding of API design, microservices, and backend system architecture
• Experience with PostgreSQL, Docker, and production deployment workflows
• Familiarity with AWS S3 operations, data processing, and backend ETL pipelines
• Basic understanding of  AI service integration (e.g. RAG systems, vector databases, LLM APIs)
• Ownership mindset, you care about reliability, performance, security, 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 deployments and GitLab CI/CD workflows
• Experience integrating AI services or reranking strategies into backend systems
• You live in or around Hamburg and enjoy working regularly in the office
