About the Project:

It's a platform for building AI-powered applications. It brings together multi-provider LLM agents, serverless Python functions, persistent state, database querying, file storage, and template rendering — all behind a single API with role-based access control.

— Participate in code reviews and contribute to continuous improvement
— Ensure system stability, security, and compliance (AVG/GDPR)
— Research and prototype new technologies (LLMs, OCR, cloud-native patterns)
— Support CI/CD, testing, and deployment automation

Qualifications:
— 5+ years of professional Python experience, ideally with microservices or AI/NLP project
— Experience with FastAPI, SQL/NoSQL databases, and cloud infrastructure
— Familiarity with Docker, Kubernetes, and GitHub Actions
— Understanding of REST APIs, authentication (OAuth2, JWT), and security best practices— Experience with frontend integration
