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

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 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
