You’ll cross‑functionally collaborate with the Data team, Engineering, Product and CRM teams, including senior stakeholders, to identify high‑value opportunities for personalisation, designing and implementing recommender systems, propensity models and scoring solutions, validating different approaches using robust A/B testing frameworks, and presenting insights and recommendations back to stakeholders.

This role offers a real opportunity for both personal and technical development and future career progression for the right person.

•

• Proactively use data to discover and size opportunities, generate hypotheses, propose, design and help run experiments and ensure we keep learning and improving
  
• Build and maintain key data products to enable business teams to self‑serve and allow quick access to core insights and metrics, embedding a data‑informed approach to decisions
  
• Manage the end‑to‑end lifecycle of our data products and machine learning models, including conception, design, feature engineering, testing, implementation, monitoring and maintenance
  
• Build, evaluate and deploy machine learning models, including classification, regression, propensity modelling, graph analysis, and causal inference
  
• Use recommender systems and personalisation algorithms to help us present the right offers to the right member at the right time through the right channel
  
• Improve our existing recommendation models, and test and implement new solutions that will allow us to serve our customer base according to their needs, preferences and behaviours
  
• Develop strong relationships with all teams at Blue Light Card, sharing learnings to maximise the access and value of insights, algorithms and data products across the business
  

• 
  
• Proven experience working with data in data science or analytics, preferably in a digitally native tech environment
  
• Strong experience with Python is essential
  
• Experience building predictive models (classification, regression, propensity modelling, graph analysis, segmentation and clustering analysis) on an industrial or academic environment
  
• Hands‑on experience with cloud‑based machine learning platforms (AWS SageMaker, Databricks, Google Vertex AI, Azure ML)
  
• A solid understanding of statistical methods, A/B testing, and experimental design
  
• Degree in a numerate subject e.g., Economics, Quantitative Social Science, Behavioural Science, Statistics, Computer Science or Engineering is preferable but not essential
  
• Understanding of search retrieval, search quality or information theory would be highly beneficial
