If you're excited by the challenge of understanding how people interact with AI, this is a rare opportunity to work on a product where your insights genuinely shape what gets built next. You'll be working with large-scale conversation and text data, helping teams understand what delivers value for users and where AI experiences can be improved.

You'll join a small, highly capable team focused on understanding user interactions with AI. The environment is collaborative, product-led, and centred around solving complex problems with real-world impact.

  • Apply NLP, semantic analysis, classification, and regression techniques to answer product questions
  • Develop frameworks to evaluate AI performance and measure user outcomes
  • Investigate prompts, model responses, and interaction data to understand what drives successful experiences
  • Turn complex analysis into clear recommendations that influence product strategy and roadmap decisions
  • Own projects end-to-end, from problem definition and data exploration through to modelling, insight generation, and stakeholder communication
  • Design and evaluate experiments to support product development and feature launches
  • Work closely with Product and Engineering teams to improve user experience and business outcomes
  • Help establish best practices for analysing unstructured and AI-generated data

  • Hands-on experience analysing high-volume text, conversation, messaging, or document data
  • Deep understanding of NLP, semantic analysis, or text-focused machine learning techniques
  • Strong Python and SQL skills

  • Proven ability to influence product decisions through data and experimentation
  • Comfortable working in ambiguous environments where problems are not clearly defined from the outset
  • Strong communication skills and experience working with cross-functional stakeholders
  • Experience in AI-native, SaaS, enterprise software, or other product-led technology businesses is highly desirable

What They Offer

  • Up to £110,000 - £125,000 base salary
  • Competitive RSU package
  • Sign-on bonus available
  • Flexible hybrid working
  • Exposure to cutting-edge AI products and large-scale user interaction data
