Head of Knowledge Graph Engineering – Data Science and Analytics
London (hybrid)
Up to £200k + B&B
This is a knowledge graph engineering, semantic modelling, graph query design, risk data, graph-grounded AI role. Knowledge graph engineers, data engineers, applied data scientists or semantic technologists with a knowledge graph or connected data application built for analytics, content or AI, taken from domain conversations to a working implementation. You will be tasked with owning what a knowledge graph is in a new data science and analytics organisation: semantic model, data mappings, queries, provenance and temporal rules, validation with domain experts, and the first working implementation.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The Role
- Graph build: initial graph models, data mappings, queries and working implementations, built personally from a live product problem and released to users
- Languages and tools: Python, SQL, Cypher, SPARQL, RDF, property graphs; no single stack required
- Semantic model: analytical domains, subjects, capabilities, methods, inputs, outputs and the relationships between them
- Relationship modelling: identity, time, provenance, validation; meaning, timing, source and limits of each relationship stated
- Risk pathways: country and industry developments linked to companies, exposures and credit outcomes
- Graph and AI: connected retrieval, grounded answers, traceable sources, answer quality assessed against real questions
- Model testing: graph relationships, features and algorithms tested with data scientists against a simpler baseline
- Content enrichment: tagging with research and content teams linking documents, topics, entities, events and analytical capabilities; source and context preserved
- Delivery: ingestion, validation and interfaces with engineering and platform teams; shared entity and identifier services; entity-linking requirements; reusable patterns; teaching partner teams
Get help with your application
Your very own career expert that helps elevate your application to the next level.
- Own the first implementation: a working graph for one priority risk or analytics question, on real data, with a model validated by domain experts and prospective users.
- Own the test: at least one adjacent use case, such as graph-derived features for a model or connected research for source-backed AI, measured against a simpler approach.
- Own the patterns: modelling patterns, working examples and an adoption plan for other teams.
