.img – itai’s machine GmbH is a digital technology company specializing in modern publishing solutions. With our “journalistic operating system” (.jOS), we offer a cloud-native publishing platform that serves millions of users by connecting to headless CMS systems, processing and enriching content, and distributing it via web and mobile applications. Our clients include national and regional media companies as well as businesses from other industries that rely on a scalable and high-performance infrastructure for digital publishing.

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
