Senior AI/ML Engineer (m/f/d)

Your mission

Most AI lives in a chat window. Ours will run physical infrastructure across a pan-European network. As a Senior AI/ML Engineer in our newly established AI UNIT within E.ON Drive Infrastructure (EDRI), a special unit built and run like a startup, you will be at the forefront of designing, building, and scaling AI systems that deliver real business impact. Working across the entire AI lifecycle, you will take solutions from experimentation to production and own them there, while helping define the technical foundation of our AI UNIT. You report to our Head of AI Strategy.

Your Responsibilities

• Shape the AI/ML architecture, technology stack, and engineering standards of the unit
• Design, build, and operate production-grade AI and machine learning systems and own their reliability, quality, latency, and cost
• Develop classical ML and GenAI solutions, including RAG, agentic systems, and AI-powered services
• Productionize ML models developed by our Data Scientists and operate them at scale
• Define and enhance MLOps and LLMOps practices for deployment, versioning, monitoring, evaluation, and retraining
• Own our LLM gateway, including model routing, token limits, cost per use case, guardrails, and logging
• Build scalable AI services and APIs for our Full-Stack and AI Deployment Engineers
• Evaluate emerging AI models, AI tooling, and agentic systems and integrate impactful innovations into our stack
• Share knowledge and support the growth of junior colleagues – this is a senior individual contributor role
