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. This internship requires a minimum commitment of 6 months and is open to Master's students in a technical field only. 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
