Pink University GmbH

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:
