Joining our applied data science team, you’ll investigate, develop, implement and deploy a range of complex applications and components while working alongside super-smart colleagues challenging and rewriting the rules, not just following them.

• A fast learner with the ability to adopt new data science techniques quickly.
• Experience designing, evaluating and interpreting controlled experiments (A/B and multi-cell tests), including defining success metrics, guardrails, and statistical significance.
• Confidence in presenting insights and recommendations to both technical and non-technical stakeholders.
• A degree in Computer Science, AI, Machine Learning, Statistics, Maths, Economics, Physics, Engineering, Biology, or a related field is advantageous but not essential.
• Knowledge of the UK retail or consumer goods industry is a bonus.
