Responsibilities
• 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. • 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. • Owning our Neo4j strategy • Optimizing Cypher queries and graph access patterns for latency, throughput, and scale • Optimizing Cypher queries and graph access patterns • Mentoring engineers and raising the team's technical bar (especially in Neo4j), without formal management authority • Mentoring engineers • Partner closely with Product Managers: to translate long-term product goals into scalable technical roadmaps • Partner closely with Product Managers: • Designing secure, scalable access control systems for mission-critical environments • Building APIs for intuitive user interaction with complex data • Building APIs • Orchestrating workflows to automate graph analytics, inference, and real-time insights • 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). • Deep, hands-on Neo4j expertise, • 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) • Modelled real domains as property graphs • Track record of leading architecture and technical direction for a team or product area, not just contributing to decisions made by others • Track record of leading architecture and technical direction • Proven ability to drive consensus: across engineering teams for large-scale architectural changes. • Proven ability to drive consensus: • Proven experience in backend systems (8+ years) with exposure to large-scale, complex applications and cross-functional teams
