Job Description:

We are seeking a Data Scientist with deep expertise in Knowledge Graphs and Ontologies and the ability to work across domains. You will design and deploy production-grade graph solutions that model relationships not only between UAVs, missions, and sensors, but across company processes end-to-end: from operations and production to HR and delivery. Your work will provide a transversal view of how data and processes interconnect, powering insights and decision-making across the organization.

Job Responsibility:

  • Ontology Design & Management: Design and maintain scalable ontologies to unify mission data, sensor outputs, flight logs, and operational parameters
  • Graph Engineering (Neo4j): Implement, optimize, and operate Neo4j schemas
  • write high-performance Cypher queries and ensure production scalability
  • Graph Data Science: Apply graph algorithms (e.g., centrality, pathfinding, community detection) and graph ML to derive actionable insights
  • Production Deployment: Move solutions from research to production (TRL > 6)
  • integrate graph models into APIs and pipelines with reliability and latency constraints
  • Data Integration: Build ingestion pipelines for structured and unstructured data into the Knowledge Graph
  • Cross-Functional Collaboration: Translate operational and domain requirements into robust data and graph models

Requirements:

  • Graph Databases: Advanced Neo4j expertise, including architecture, drivers, administration, and Cypher
  • Ontology & Semantics: Strong experience with data modeling, ontologies, and semantic technologies (RDF, OWL, SPARQL)
  • Programming: High proficiency in Python (pandas, networkx, py2neo, neo4j-driver)
  • Graph ML: Experience with Neo4j GDS or frameworks such as PyTorch Geometric or DGL
  • Production Engineering: Hands-on experience with Docker, REST APIs (FastAPI/Flask), and CI/CD pipelines
  • Core Data Science Profile: 3+ years of experience in Data Science or Data Engineering
  • Experience with NLP for entity and relationship extraction is a plus
  • Strongly skilled in standard ML workflows (Scikit-Learn, XGBoost)
  • Experience with geospatial data (GIS, GeoPandas) is valued
  • Education: MSc in Computer Science, Data Science, or a related engineering field (PhD welcome, but practical delivery is prioritized)
  • Profile We’re Looking For: Production Builder: You focus on deploying reliable systems, not just experiments
  • Versatile Specialist: Deep in graph technologies, comfortable across the full data stack when needed
  • Structured Thinker: You value strong data models, data quality, and long-term maintainability

Nice to have:

  • Experience with NLP for entity and relationship extraction
  • Experience with geospatial data (GIS, GeoPandas)
What we offer:
  • An excellent work environment and an opportunity to make a difference
  • Salary Compatible with the level of proven experience
