🚀 The RoleAs a Senior Data Scientist at ZOE, you will partner with product, engineering, and science to turn data into valuable insights and features that shape our product and drive impact across the organisation. You’ll lead analyses that guide product decisions, build and evaluate ML/AI models, and contribute to production-ready data solutions.This role is ideal for someone with genuine curiosity and a drive to uncover insights from data. We’re looking for a generalist with a strong track record of applying data science to solve business and product problems.
👥 The TeamYou’ll be joining the Data Science team at ZOE, which works closely with stream-aligned product squads while also dedicating time to high-impact, cross-cutting initiatives that support the wider organisation.The team drives three core work streams: science-led features, AI-powered products, and data-driven product development. In practice, this means turning cutting-edge research into features our members use every day, building intelligent systems that personalise and scale the ZOE experience, and conducting deep-dive analyses that shape product strategy and move science forward. By working across these areas, the team plays a pivotal role in shaping both what we build and how we deliver value to our members.

🎯 What You’ll Be Doing

• Design, build, and deploy data-driven features and ML models that improve our product and user experience.
• Develop and iterate on evaluation frameworks to continuously improve our AI features.  
• Write, test, and maintain clean, production-ready code in Python (pandas, NumPy, scikit-learn), and SQL/DBT/BigQuery/Airflow.
• Partner with product managers to run analyses that uncover insights and guide decisions.
• Collaborate with engineers to define data contracts and ensure pipelines meet requirements for granularity, latency, and quality.
• Communicate findings through decks, dashboards, or Looms to drive data-informed decisions.
• Take full ownership of your work (i.e. from ideation to model development and deployment). 
• Bringing an entrepreneurial mindset to your day-to-day work and love to go above and beyond.  
• Champion our scientific yet agile approach: start with a hypothesis, seek evidence, and iterate fast.

🌟 We think you would be great if you…

• Proven experience building and evaluating ML/AI models and conducting product-focused analyses.
• Strong foundation in statistics, including hypothesis testing, experiment design, and causal inference.
• Hands-on experience with production-level Python codebases, developing substantial components and features, plus strong SQL skills.
• Track record of shipping production code/models and collaborating with engineers in fast-paced environments.
• Comfort using AI tools to enhance day-to-day productivity—from IDE assistants to prompt engineering.
• Curiosity and drive to use data to uncover insights and create business value.
• Excellent communication and collaboration skills, from delivering clear presentations to stakeholders to conducting deep-dive code reviews.
