• You implement AI-powered workflows, including retrieval-augmented generation (RAG), to enhance automation and decision-making
• You apply basic ML techniques (e.g., clustering) to organize and process data efficiently in an engineering context (no deep ML expertise required) 
• You contribute to the full AI stack, from backend engineering to AI service deployment, with a strong engineering approach
• You develop and maintain frontend components (React) where needed to support AI-driven applications 
• You ensure scalability, monitoring, and maintainability of deployed AI solutions in a cloud-native environment (AWS, Kubernetes, GitOps)

Your profile

• You hold a university degree in computer science/engineering, mathematics, economics or you have an equivalent working experience of minimum 3 years in data analysis or data engineering role
• You have experience in building and integrating data-driven backend services and are comfortable working with AI-powered solutions
• You are proficient in Python, APIs, PostgreSQL, and cloud environments (AWS), with the ability to connect different systems and deploy AI services
• You understand basic machine learning concepts such as clustering and their practical applications in data engineering
• Excellent interpersonal skills, team spirit, and a high degree of self-motivation
• You are proactive, result-oriented and have strong analytical skills
• You enjoy solving complex problems, learning new technologies, and delivering impactful AI applications
• You understand modern cloud architectures, CI/CD, and containerization to ensure reliable and scalable AI systems
