This is an opportunity to shape how AI-powered products are measured, tested and optimised in a live commercial environment. You will take ownership of experimentation delivery across AI-native customer experiences, ensuring every product change is assessed against meaningful business outcomes such as conversion, containment and customer satisfaction.

The Company

They are a data and technology-led organisation delivering AI-powered digital products alongside an established web estate.

• Extend and manage feature flagging capabilities across the product estate using LaunchDarkly or a comparable platform
• Configure, validate and troubleshoot experiment tracking, analytics instrumentation and event collection
• Define and review event schemas, data layer specifications and tracking requirements, including experiment exposure and AI-related metadata
• Work closely with analytics and senior stakeholders to evaluate the commercial impact of product and AI changes
• Support experimentation across conversational agents, AI advisors and LLM-powered decisioning experiences

Your Skills & Experience

• Strong hands-on experience delivering experiments in production environments, including implementation, debugging and live releases
• Practical experience with LaunchDarkly or a comparable feature flag management platform
• Working knowledge of experimentation platforms such as Adobe Target, Optimizely, or similar tools
• Experience working with AI or LLM-powered products, conversational interfaces or intelligent customer journeys
• Strong understanding of analytics implementation, event tracking, data layers and experimentation measurement
• Ability to operate independently in a remote, cross-functional environment
• Exposure to Microsoft Azure, Azure AI services, prompt engineering, API integrations or agent orchestration is beneficial
• Familiarity with AI architectures such as RAG, tool usage or multi-agent workflows is advantageous
• Experience within telecoms, e-commerce or subscription-based digital products is a plus
• A commercially focused mindset, with the ability to assess success through customer and business outcomes rather than technical delivery alone
