About Yoto

Yoto is a screen-free interactive audio platform for kids. We make carefully connected audio players that kids control, with no microphones, cameras or ads. We have a catalogue of audio that inspires creative play and learning with 1,000+ titles in our card store from top creators, publishers and labels – think Disney, Marvel, Roald Dahl and Universal Music. We also create Yoto Originals like BrainBots.

Yoto’s Data Team

We’re a small team at the heart of all the decisions Yoto makes. We work in a high‑trust environment with a lot of independence. Everyone can contribute ideas and be part of the decision making process. We tackle a broad range of problems, from developing cutting edge data solutions to maintaining and building data ingestion pipelines, query and orchestration platforms, our work spans across all the key strategic projects throughout the company.

What you’ll be doing:

• Partner with product and commercial teams to understand customer behaviour, and turn that into decisions people actually act on.
• Help create experimentation frameworks and approaches, that maximise our ability to learn quickly and confidently about customer experiences.
• Use non‑experimental modelled approaches to help measure the impact of product features and growth projects, making clear the limitations and uncertainties.
• Defining the metrics that decisions actually hang on, and making sure people know what a result really means, and what it doesn’t.
• Working to improve the efficacy of our internal LLM solutions, helping stakeholders navigate their own analysis and results, communicating uncertainties and risk as well as opportunities.

What you’ll bring:

• Experience in data science roles, with a track record of influencing product or business decision making with data, insights and solutions.
• Applied experience in statistics and probability, strong grounding in experimentation and causal inference methods.
• Proven experience in navigating priorities across senior stakeholders, good judgement about where to spend effort, and being able to lead the direction of projects.
• Proficiency in SQL and python, and experience working with modern data stacks (e.g. GCP, AWS, Snowflake).
• Comfortable with ambiguity and excited by the opportunity to shape how data drives decision‑making at Yoto.
• Ability to translate complex data findings into clear, compelling narratives for both technical and non‑technical audiences.
