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&amp;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.
<h2>Tasks</h2>
<ul>
<li>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.</li>
<li>AI Infrastructure: Engineer, deploy, and maintain performant agent and LLM serving infrastructures both locally and in the cloud.</li>
<li>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.</li>
<li>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.</li>
<li>Semantic Digital Twins: Translate real-world physical workflows into semantically-typed knowledge graphs.</li>
</ul>
<h2>Requirements</h2>
<ul>
<li>Technical Core: Deep practical experience with Agentic frameworks, orchestrators, or tool-use libraries.</li>
<li>Software Engineering: Strong proficiency in Python and/or JavaScript, with a focus on writing clean, modular, and well-tested production code.</li>
<li>Modeling Skills: Hands-on experience building, training, or fine-tuning models using machine learning frameworks like PyTorch or similar.</li>
<li>Validation: Familiarity with SHACL, RDF, RDFS, OWL, and SPARQL or similar (like CYPHER) validation languages is a strong plus.</li>
<li>Background: A degree in Computer Science, Information Science, or, Chemistry, Materials Science, Mechanical Engineering, or a related field.</li>
<li>Mindset: You are meticulous and logical. You enjoy solving the puzzle of how to structure the world into a database.</li>
</ul>
<h2>Benefits</h2>
<ul>
<li>Flexible working hours</li>
<li>Free beverages</li>
<li>Public transportation benefits</li>
<li>Remote work possible</li>
<li>Travel expenses compensation</li>
</ul>
This is the future of scientific AI. At datin GmbH, you won't just be writing code; you will be defining the grammar of scientific discovery. If you are ready to build the engine that powers the next generation of R&amp;D, apply now and let's shape the future together.
