• Graph Technology – Familiarity with RDF, SPARQL, OWL and ideally Graph Neural Networks

• Vector Databases – Experience with Pinecone, Weaviate or Chroma

• NLP & Semantics – Understanding of Natural Language Processing, semantic search, and embedding models

• Education & Experience – Degree (BSc/MSc) in Computer Science, Data Science, AI/ML or similar field and 3+ years of experience in AI/ML projects, including at least 1 year in Knowledge Graphs

• Languages – Excellent English skills required; German language skills are a plus

• Mindset – Structured, collaborative, communicative and proactive personality

What we offer:

• Innovation & Impact – Work on real AI applications with measurable business value

• Modern Tech Stack – Access to powerful computing environments and the latest ML/AI frameworks

• Freedom to Explore – Space for research, experimentation and publication of new Graph+LLM approaches

• Team Culture – Agile workflows (Scrum/Kanban), flat hierarchies and collaboration on equal footing

• Hybrid Work Model – Flexible working hours, remote options and a well-equipped office in Wrocław

• Learning & Development – Individual trainings, certifications, conference participation in the AI/ML field
