Applied AI Engineer Intern (m/f/d)

Are you passionate about building intelligent systems that make a real impact at scale? As an Applied AI Engineer Intern (m/f/d) at SIXT, you will design and build AI-powered solutions that transform how one of Europe's leading mobility companies operates globally — from intelligent automation to agentic workflows and predictive systems. Working alongside experienced engineers in our Headquarter, you will turn complex challenges into working prototypes and see your solutions deployed in a real production environment. Ready to shape the next generation of AI-driven innovation? Apply now and join Team Orange!

YOUR ROLE AT SIXT

• You support the design and development of scalable, production-ready AI automation frameworks and agentic workflows that integrate into SIXT's technology ecosystem
• You help translate complex business challenges into technical solutions, exploring agentic architectures, MCP integrations, predictive models, and neural networks
• You contribute across the full product lifecycle — from prototyping and API development to deployment — in close collaboration with our Software Engineering teams
• You experiment with and benchmark modern GenAI frameworks, evaluate the most effective approach for a given problem, and share your learnings with the team
• You write clean, well-structured Python code and actively contribute to our tech stack
• You collaborate with engineers and business leaders, turning requirements into impactful, working data products

YOUR SKILLS MATTER

Academic Background

You are currently enrolled in a Master's program in a STEM field (e.g. Computer Science, Data Science, Mathematics, Physics, or Engineering) and bring a strong technical foundation, with strong academic performance

Programming

You write clean Python code and have a solid understanding of core computer science and machine learning concepts, demonstrated through university projects, coursework, or personal work

AI Expertise

You are familiar with modern GenAI frameworks and agentic patterns (e.g. LangChain, MCP) and have hands-on exposure to Deep Learning frameworks and classical ML libraries like scikit-learn or XGBoost

Technical Know-How

You are comfortable working with Git, have first experience with API development (e.g. FastAPI) and containerization tools like Docker; exposure to cloud platforms is a plus

Product Mindset & Execution

You focus on real impact and combine solid technical depth with a hands-on, get-things-done mentality — picking the most effective solution whether that means simple heuristics, a classical ML model, or a complex neural network — and thrive in fast-paced, high-ownership environments

Communication

You translate complex AI concepts and black-box logic into clear insights for both technical and non-technical audiences and communicate fluently in German
