You will lead the design and implementation of graph-based models to solve high-impact problems—ranging from fraud detection and recommendation engines to complex GraphRAG architectures. As a Neo4j specialist, you will turn interconnected data into a strategic competitive advantage for our clients. You are a perfect candidate if you are growth-oriented, you love what you do, and you enjoy working on new ideas to develop exciting products and growth features.   What we are looking for:   3+ years of hands-on experience specifically with Neo4j and its GDS library. Expert proficiency in Python Deep understanding of graph theory, network science, and linear algebra. Experience with ETL/ELT pipelines to move data from relational databases or data lakes into Neo4j. Proven track record of deploying ML models into production environments (Docker, Kubernetes, or Cloud-native ML platforms). Beyond Cypher, a solid grasp of SQL is essential for data preparation. Time zone: CET (+/- 3 hours). We are unable to consider applications from candidates in other time zones.   Responsibilities:   Design and architect scalable graph schemas in Neo4j that represent complex real-world entities and their relationships. Use the Neo4j Graph Data Science (GDS) library to implement centrality, community detection, similarity, and pathfinding algorithms. Build and productionize machine learning models that leverage graph features (node embeddings, Graph Neural Networks) to improve accuracy over traditional ML approaches. Write and optimize complex Cypher queries to extract insights and power real-time applications. Collaborate with AI engineers to integrate Knowledge Graphs into LLM workflows, improving the factuality and context-awareness of generative AI solutions. Use tools like Neo4j Bloom or Linkurious to translate complex graph insights into actionable stories for stakeholders.     What we offer:   Get paid, not played No more unreliable clients.
