We are looking for a Senior Backend Engineer (m/f/d) to join our team as soon as possible.

Tasks

• Design, develop, and maintain backend services and APIs for our content platform using Python, and FastAPI
• Build reliable pipelines that transform raw and heterogeneous data into structured, production-ready content
• Develop and integrate production-grade LLM workflows, including prompting, structured outputs, embeddings, similarity search, and evaluation
• Build resilient integrations with third-party APIs, REST services, and webhooks
• Design and maintain asynchronous processing workflows using queues, and Redis
• Contribute to our TypeScript services where needed
• Contribute to architecture, code quality, technical standards, and continuous improvement of our backend stack

Requirements

• 6+ years of professional backend engineering experience
• Strong Python expertise, including FastAPI and pydantic
• Working knowledge of TypeScript — enough to read, debug, and contribute to our TypeScript services
• Experience with AI automation — building systems that integrate, govern, or orchestrate LLM-driven workflows, not just calling an API
• Experience with Redis and message queue based asynchronous processing
• Strong testing discipline (pytest) and track record of owning features end-to-end, from architecture through delivery

Nice-to-have

• TypeScript/Node.js experience, e.g. with frameworks such as NestJS
• AWS or other cloud infrastructure experience
• Experience with data pipelines handling heterogeneous/unstructured input
• Familiarity with vector search / embedding stores
• Prior experience integrating with third-party content or media APIs
