.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

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

Secure Future: Permanent employment with a trust-based work schedule and a high degree of personal responsibility
Work in the heart of Berlin: A modern office right on Alexanderplatz with an impressive view of the city and excellent public transportation connections
Appreciative corporate culture: An open, collegial atmosphere where individual perspectives matter and teamwork is a way of life
