Senior Software Engineer - GraphAware Hume

The Team:

Product Engineering at Neo4j GraphAware offers a unique opportunity to build real-world intelligence systems that matter.
We are aiming to hire someone in the the UK, Czechia or Italy.

• Build with purpose: Your code will help law enforcement and analysts save lives and protect communities through better data insight.
• Innovative tech: Work with knowledge graphs, workflow engines, LLMs, and graph-native UIs pushing the boundaries of data analytics.
• Shape the future: Contribute to product direction and technical vision alongside a senior engineering team.
• True autonomy: Own your work, from ideation to deployment, in a remote-first team.
• Global mindset: Collaborate with a world-class team of engineers, data scientists, and product thinkers across Europe and beyond.
• Growth without bureaucracy: Develop your skills in a non-micromanaged, excellence-driven environment

The Role:

As a Senior Software Engineer, you will shape the core intelligence of GraphAware Hume, our graph-powered analytics platform.

Your responsibilities will include:

• Building APIs for intuitive user interaction with complex data
• Designing secure, scalable access control systems for mission-critical environments
• Orchestrating workflows to automate graph analytics, inference, and real-time insights
• Optimizing application performance and collaborating with other engineers to ensure seamless user experiences
• Contributing to architecture and technical design with the team

What you must know already and be excited to grow further

• Proven experience in backend systems (8+ years) with exposure to large-scale, complex applications and cross-functional teams
• Fluency in Java, with a deep understanding of modern software engineering principles, including:
  • Clean Architecture, Domain-Driven Design (DDD), and Test-Driven Development (TDD)
  • Advanced debugging and profiling techniques,
  • Writing composable, maintainable, and testable code
• Spring or similar frameworks with emphasis on building secure, modular, and scalable APIs
• Experience designing data models, both relational (e.g., PostgreSQL) and ideally graph-based (Neo4j or similar)
• Working knowledge of modern CI/CD pipelines, containerization (Docker), and automated deployment workflows
• Strong security mindset, with practical knowledge of secure software design and common vulnerabilities (e.g., OWASP)
• Comfortable with remote team collaboration, i.e. tools and practices for asynchronous communication

Bonus points for familiarity with:

• Graph technologies: Cypher, Neo4j, knowledge graph
• Event-driven architectures, Kafka, or distributed systems
• Cloud-native development, observability, and performance tuning
• Experience working with LLMs or integrating AI/ML into production systems
