About the project

We’re taking over and continuing the development of a Neo4j-based web platform.

The platform processes complex, interconnected datasets used in real analytical workflows, enabling you to work with real-world graph structures at scale. You will have a direct impact on architectural decisions during the transition and scaling phase, not just maintain legacy code. It’s a rare opportunity to shape a production-grade Neo4j environment that is actively used by global teams.

The project is in the transition and scaling phase, focused on knowledge transfer and further feature development.

It’s a long-term international project (min. 2 years), offering stable collaboration and room for technical growth.

Your responsibilities
  • Design and maintain graph data models using Neo4j
  • Develop and optimize Cypher queries and custom Java integrations
  • Improve database performance, indexing, and scalability
  • Collaborate with data scientists and backend developers on analytics features
  • Ensure data security, documentation, and stable operations
  • Participate in knowledge transfer and onboarding of new team members
Our requirements
  • 5 years of experience in software engineering
  • At least 2 years of hands-on experience with Neo4j and Cypher
  • Strong knowledge of Java and graph theory concepts
  • Experience building custom extensions or plugins for Neo4j
  • Familiarity with distributed systems, microservices, and cloud platforms (AWS / Azure / GCP)
  • Understanding of CI/CD, Git, and modern DevOps practices
  • Higher education in Computer Science, Mathematics, Physics, or a related field
  • English at a communicative level (B2/C1)
Optional
  • Experience with knowledge graphs or machine learning integration
  • Academic or research background (lecturer, professor, researcher)
  • MSc or PhD degree in a technical discipline
  • Certifications such as Neo4j Certified Professional or AWS Data Engineer
