AI Platform Architect

Role Purpose:

We are building a new AI team in our Chief Data Office, and this is one of its first hires. You will shape the enterprise AI platform behind our UK insurance business: agentic AI, large language models and machine learning in the cloud, working with colleagues across the business and the wider group. Your designs will go live in real products across underwriting, claims, pricing and data, rather than stopping at slides or proofs of concept. 

In this role, you'll make an impact by:

• • Architect the platform: own the platform's end-to-end cloud architecture: model access, orchestration, guardrails, evaluation, observability and cost controls. 
  • Make agentic AI real: define the reference patterns for AI agents, retrieval-augmented generation (RAG), tool use and multi-agent workflows, and prove them in production with our first business use cases. 
  • Lead design authority: review and approve solution designs for the platform and for AI products; provide the architecture evidence for our lifecycle gates; keep a clear record of design decisions. 
  • Bring machine learning onto the platform: design how existing and new machine learning models are deployed, served and migrated onto the platform. 
  • Power the data products: act as technical lead for AI agents and LLM-based data quality on our data platform, and design how they connect to the AI platform. 
  • Choose the right technology: evaluate new models, frameworks and tools quickly and honestly, and turn what you learn into platform capabilities, standards and architecture decision records. 
  • Build safety in from the start: embed security, data protection, responsible AI and regulatory controls into the platform so they come as standard rather than being added at the end. 
  • Raise the bar: mentor platform and AI engineers, run design reviews and share patterns that every team can reuse. 
  • Represent AI architecture: work with enterprise architecture, cyber security and cloud teams, and present the platform direction in governance forums. 

Your skills and experience:

• • Hands-on experience as an AI platform architect, AI or platform engineer, machine learning engineer or data scientist, including designing cloud or data platforms used by several teams. 
  • A hands-on data science or machine learning background: you understand the models and workloads, not only the infrastructure. 
  • You have designed and delivered AI or ML platforms in production on AWS or Azure, personally and not only as an adviser.  
  • Experience with Amazon Bedrock and SageMaker or equivalent in Azure is a strong advantage. 
  • Hands-on knowledge of generative AI architecture: LLM hosting and access, RAG, vector search, guardrails, evaluation and prompt management. 
  • Practical experience with agent frameworks and patterns, and a clear view of what works in production and what is still hype. 
  • Strong cloud fundamentals: networking, identity and access management, security controls, infrastructure as code and CI/CD.
