Agentic AI for Science - Developer (m/f/d)

Hey there! We're datin GmbH, and we are building the "new power grid" for scientific innovation. Traditional scientific knowledge is still largely hidden from LLMs because physical R&D data (like lab experiments, simulations, and equipment logs) is rarely recorded in a structured, machine-actionable way. Text alone isn’t rich enough to support automated discovery. To bridge this gap, we have built an ontology-driven, schema-based knowledge graph management system. Now, we are taking it to the next level: building autonomous, goal-oriented AI agents that can interact directly with our graph databases, augment them with new data, and identify emerging patterns in physical science. This role offers a unique opportunity to design production-grade AI agent systems from scratch, collaborating closely with experienced material scientists, tribologists, and software engineers. At datin, we value curiosity, impact, and trust, and we design our agent-driven workflows to empower scientists, not replace them. Tasks Agentic Workflows: Design and build end-to-end agentic architectures. You will build tool-calling loops, memory layers, and execution environments that allow agents to query, update, and validate our graph databases. AI Infrastructure: Engineer, deploy, and maintain performant agent and LLM serving infrastructures both locally and in the cloud. Graph-Grounded LLMs: Fine-tune or optimize open-source LLMs to reliably translate natural language scientific requests into structured queries sent to our SDK and accurately traverse complex ontologies. Machine Learning for Science: Train and integrate specialized ML models to solve multi-objective optimization problems (e.g., predicting material properties or chemical reactions) that AI agents can use as tools. Semantic Digital Twins: Translate real-world physical workflows into semantically-typed knowledge graphs. Requirements Technical Core: Deep practical experience with Agentic frameworks, orchestrators, or tool-u
