Do you want to shape how one of Europe's leading AI products measures success? Have you worked with large-scale text, conversational or semantic datasets to uncover product insights? Are you ready to influence product strategy through data rather than just reporting on it? We're hiring for a well-funded AI-native scale-up building one of the world's leading AI video generation platforms. Their technology enables users to create avatar-led videos from text and is used globally across training, internal communications, sales enablement and marketing. Having achieved significant growth and enterprise adoption, they are investing heavily in understanding how users interact with AI products and how those experiences can be improved. This role sits at the intersection of Product, Data Science and AI. You'll analyse large-scale conversational datasets, build evaluation frameworks for AI-native features, and directly influence product decisions through experimentation and insight generation.
