The Role:**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.

What you will be doingAs 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.

• Optimizing Cypher queries and graph access patterns for latency, throughput, and scale

• 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
