Tech Lead, Backend - GraphAware Hume

Neo4j is the

graph intelligence platform that transforms data into knowledge to power the next generation of intelligent applications and AI

systems. It includes enterprise-ready knowledge graphs for accurate, explainable, and governed AI; the most comprehensive,

trusted, and easy-to-deploy graph capabilities across any environment and data source; and an unmatched ecosystem trusted by 84 of

the Fortune 100 and supported by the world’s largest graph community. Intelligence that works. Results that matter.

Built to work everywhere and integrate with everything across every cloud for dynamic, personalized, and autonomous AI systems.

We deliver quicker results, contextual knowledge, and solutions that impact customers and employees across the business.

As business, society and knowledge become increasingly connected, our technology promotes innovation by helping

organizations to find and understand data relationships. We created, drive and lead the graph database category, and we’re

disrupting how organizations leverage their data to innovate and stay competitive.

We are aiming to hire someone in the the UK, Czechia

or Italy.

​

Product Engineering at GraphAware offers a unique opportunity to build real-world intelligence

systems that matter.

• 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.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.

As Tech Lead, you will own core

parts of the platform layer of GraphAware Hume, our graph-powered analytics platform — the foundations that cut across every

development group and that every feature team builds on. You'll be sought out across the organisation for technical guidance on

graph architecture, and expected to anticipate issues at the product level before they surface. Neo4j sits at the heart of the

product, we need someone who goes beyond using it well, and actively tracks new features, tests them against real workloads, and

identifies where they can move the product forward. Working hands-on with Neo4j at the heart of the product, you will drive the

architecture that lets us model, query, and scale the knowledge graphs our users depend on.

Your responsibilities

will include:​

Driving platform architecture, setting technical direction for the transversal foundations

that feature teams across Hume build on, and shaping cross-cutting design decisions with the wider engineering group​

• Owning our Neo4j strategy​: actively tracking and hands-on testing of new releases and ecosystem tooling

(GDS, APOC, etc.) to assess breaking changes, propose new product opportunities, and plan deliberate, scalable migrations.

• Mentoring engineers​ and raising the team's technical bar (especially in Neo4j), without formal management

authority

• Partner closely with Product Managers:​ to translate long-term product goals into

scalable technical roadmaps

Designing secure, scalable access control systems for mission-critical

environments​

What

you must know already and be excited to grow further​

• Deep, hands-on Neo4j expertise,​

including advanced Cypher query performance optimization, profiling, and deep familiarity with the broader Neo4j ecosystem (e.g.,

GDS, APOC, drivers).

• Modelled real domains as property graphs​ and can reason about nodes, relationships,

labels, and properties as a first-class design activity (relational modelling with e.g. PostgreSQL is a plus)

• Track record of leading architecture and  technical direction​ for a team or product area, not just

contributing to decisions made by others

• Proven ability to drive consensus:​ across engineering teams for

large-scale architectural changes.

• Proven experience in backend systems​ (8+ years) with exposure to

large-scale, complex applications and cross-functional teams

• Fluency in Java (or a strong JVM background you can

bring to a Java codebase)​, 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

• 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)

• Knowledge graphs and GraphRAG: ​building knowledge graphs

and grounding LLMs with graph-based retrieval (e.g. neo4j-graphrag, LangChain, LlamaIndex)

• Graph algorithms and

analytics: ​(pathfinding, centrality, community detection) via Neo4j GDS, plus event-driven architectures, Kafka, or

distributed systems

• Evolving large graph data models: ​over time: schema refactoring, migrations, and

versioning as the domain grows

• Cloud-native development: ​observability, and performance tuning
