What you’ll bring
Essential Experience
Practical experience building with AI and agentic technologies: large language models, RAG, prompt engineering, and agent frameworks / orchestration (such as LangChain, LangGraph or Semantic Kernel).
Hands-on experience using AI coding assistants and agentic development tools (e.g. GitHub Copilot, Claude Code, Cursor) in a professional delivery setting, and the ability to critically review, validate and secure the code they produce.
Strong hands-on software engineering experience (minimum 10 years commercial), with React and/or Angular, TypeScript, C# / .NET and Python.
Hands-on commercial experience in Azure cloud, using GitHub and Azure DevOps, across all phases of the SDLC and Agile delivery.
Proven ability to rapidly prototype and validate ideas, moving a concept from whiteboard to working demo in days.
Demonstrable experience leading, influencing and mentoring through hands-on contributions.
Experience of working in a financial services organisation, preferably with exposure to the insurance industry / insurance broking. Where this directly relevant experience is not available, we will be looking for an ability to rapidly become effective in a new, unfamiliar environment.
First-rate communication skills, applied to rapid and creative problem solving with technical and business stakeholders in an occasionally pressurised environment.
Comfortable working on your own initiative or as part of a broader project team, remotely or face to face, and confident challenging established approaches.
Desirable Experience:
Experience running AI / LLM solutions in production at scale, including evaluation frameworks, guardrails and cost management.
Experience designing or orchestrating multi-agent workflows, and familiarity with agent protocols (e.g. MCP) for integrating AI agents with engineering pipelines and enterprise data.
Experience with microservice based architectures and containerisation.
Experience building and working with mathematical algorithms, or with geospatial, catastrophe or financial-modelling data.
Experience understanding and translating complex business processes across multiple stakeholder groups.
