Description

Senior AI Platform Engineer – Up to £90,000 Base


Hybrid: 1–2 Days per Week On‑Site (South West London)


A tech‑led insurer is scaling a new AI function and hiring an AI Platform Engineer to build production‑ready AI systems on GCP. This is one of the first hires into a newly created AI organisation, with the mandate to make the business the UK’s first fully AI‑powered insurer.


What You’ll Do

  • Build and operate production‑grade AI agents on GCP using Google’s ADK
  • Integrate AI systems with policy, claims and CRM platforms via REST/JSON APIs
  • Develop scalable RAG pipelines including ingestion, text processing and vector search
  • Implement evaluation, monitoring, A/B testing and cost/latency dashboards
  • Shape architectural patterns, engineering standards and wider AI strategy
  • Work across key AI products including claims automation and internal retrieval tools


Role Requirements

  • Background in Data/ML Engineering or Software Engineering with strong applied AI experience
  • Deep expertise in GCP (Vertex AI, BigQuery, Cloud Run/Functions, ADK, Model Garden)
  • Strong Python and API development experience
  • Hands‑on with LLMs, embeddings, RAG, vector databases
  • Proven track record building production‑ready AI systems with observability and testing
  • Solid DevOps capability: CI/CD, Docker, Kubernetes

  • Work Environment & Location

    • 1–2 days per week on‑site in either:
    • South West London
    • Hybrid flexibility the remainder of the week


    Key Products You'll Impact

    • Claims Automation (Agentic AI): End‑to‑end automated claims processing focused on efficiency, indemnity savings and cost reduction
    • Internal AI‑powered retrieval tool already live and expanding across internal platforms


    Why Join?

    • Direct and visible impact on P&L, cost savings and operational performance
    • A fast feedback loop — far quicker than large insurers or corporates
    • Significant “low‑hanging fruit” in automation and workflow optimisation
  • Opportunity to build agentic systems from the ground up
  • Backed investment and a roadmap to scale the AI team to 10+ people
  • Chance to be part of a pivotal transformation as the organisation becomes an AI‑powered insurer
