LichtBlick serves 1.7 million customers as Germany's leading pure-play renewable energy supplier, now building agentic AI systems across billing, meter management, and process automation. The tech stack reveals a rapid pivot toward AI infrastructure: Azure OpenAI, LangChain, PyTorch, and RAG pipelines sit alongside core .NET and Python services, while active projects span automated billing, smart meter workflows, and responsible AI production. Hiring velocity is accelerating with a skew toward interns and engineering roles, suggesting either a structured AI apprenticeship program or aggressive scaling of junior technical capacity for new product lines.
