Senior AI Engineer (m/f/d)

Join us to make education accessible for all!

Strengthen our Syntea AI team in full-time (40 hrs./week) as Senior AI Engineer (m/f/d) within Germany or UK remotely or at one of our office locations.

In this role you'll help build the AI systems behind Syntea, IU's own AI-powered learning assistant and a critical part of IU's AI-first strategy. Syntea acts as a personal AI tutor for IU's distance-learning students, now supporting more than 80,000 learners with conversational tutoring, adaptive learning, study organization, and administrative tools in a single chat-based platform. As an AI engineer, you'll help design and build the LLM- and agent-powered services that make all of this work, at scale and in production.

Your tasks

• Help build and maintain the backend services and APIs that power Syntea, its domain agents, and AI-driven micro-apps.
• Develop LLM-powered and agentic pipelines — prompting, retrieval (RAG), orchestration, and tool use — ensuring scalability, modularity, and reliability across the Syntea ecosystem.
• Partner with Product and other engineers to turn research ideas and prototypes into robust, production-grade AI services.
• Help test and evaluate AI features — from prompt and model evaluation to monitoring and continuous improvement in production.
• Own data engineering for personalization: turn existing student data (study goals, usage patterns, gamification signals) into personalized, context-aware responses and proposals.

Your Profile

• 5 years of professional software/AI engineering experience, with solid Python skills and some experience shipping production services in a product team.
• Deep, hands-on experience building production LLM/AI systems — retrieval, tool use, orchestration — ideally including multi-agent or agentic architectures. AI depth is the heart of this role.
• Experience with AI evaluation and quality (offline/online eval, automated analysis of model outputs) and a rigorous, data-driven mindset.
• Solid data engineering ability: modeling and pipelines that feed personalization and analytics.
• Awareness of AI security and safety considerations in user-facing systems.
