Acorn Insurance is hiring an AI Engineer for our Fraud AI Team. This is a focused, hands-on role with one clear opening priority: take ownership of our Neo4J-based fraud detection solution. After that, there is a meaningful backlog of Fraud AI work waiting - detection workflows, casework support, signal generation - and the engineer who takes this role will be the one shaping how we deliver it. Acorn is FCA-regulated, with Consumer Duty and UK GDPR shaping how AI gets built and run. Fraud work in particular needs to be auditable and defensible - that is a design constraint, not an afterthought. Fraud is one of the highest-stakes places AI gets deployed in insurance. The work you do here directly affects detection rates, investigator productivity and customer outcomes. You'll own a meaningful piece of capability from day one - the Neo4J solution - with a backlog of follow-on work behind it, executive backing, and a small focused team where individual contribution shows. Acorn delivers non-standard insurance for a non-standard world; the Fraud AI role is non-standard engineering for non-standard problems. Job Title: AI Engineer – Fraud Salary: Up to £45,000 depending on experience Working hours: 37.5 hours per week, Monday to Friday 9am to 5:30pm Location: Liverpool City Centre on a Hybrid working basis What you will be doing Take ownership of the Neo4J network graph solution for Fraud: schema, ingestion, queries, performance, evolution. Work through the Fraud AI backlog - detection workflows, casework support, fraud signal generation, investigator-facing tooling. Build and ship in n8n and AI Foundry / Requesty, integrating Neo4J outputs into investigator workflows. Partner with the existing Fraud AI Engineer on priorities, design and delivery; share load and context. Stakeholder management with Fraud ops and the Fraud SLT - translate operational concerns into deliverable work. Make sure outputs are auditable and defensible - documentation, logging, evaluation and human-in-the-loop where the risk profile demands it. Lean on the Central / Group team for platform support, observability standards and burst capacity when needed. Work within a regulated AI governance model: DPIAs, model documentation, observability, human-in-the-loop where appropriate. What we are looking for Solid engineering background with production experience shipping software or AI / ML-backed systems. You've built things people rely on, not just prototypes. Strong working knowledge of graph databases - Neo4J specifically, or comparable (TigerGraph, Amazon Neptune). Cypher fluency is a real plus. Databricks experience is a strong plus - it underpins our wider data platform and Fraud AI work increasingly touches it. Comfort with Python, REST / webhook integration, JSON, and at least one workflow / orchestration tool (n8n preferred given our stack). Working comfort with YAML - it shows up everywhere in configuration, CI and infrastructure-as-code. Easy to pick up; expected as table stakes. Working knowledge of LLM application patterns: RAG, structured extraction, evaluation, agentic workflows - enough to use them where they're the right tool. Domain exposure to insurance fraud, financial crime, or a comparable detection / investigation function is a strong advantage. Awareness of the constraints of regulated environments: auditability, defensibility, data residency, model risk - design around them, don't work against them. Comfort working in a small team where you own outcomes end-to-end - hands-on delivery, not just direction. Cloud familiarity (Azure preferred) without needing to be a platform engineer - that work sits with the Central / Group team. Formal AI/ML credentials are not a hard requirement. Demonstrable delivery, sound judgement and the ability to ship into a regulated environment matter more. Grow with Acorn We run through walls for our customers and each other We challenge the status quo We succeed when we help those around us succeed We decide quickly when the smart thing to do is use our judgement Benefits A maximum of 35 days’ holiday (depending on role and tenure) including bank holidays, with additional buy/sell options 24/7 mental health support
