• Act as a subject-matter expert for data science across the business

What we’re looking for

• Strong experience with Python and SQL (model building, analysis, visualisation)
• Solid understanding of data science techniques and libraries (Pandas, scikit-learn, supervised & unsupervised models, tree-based models)
• Proven experience with customer analytics (e.g. churn, CLTV, segmentation) - required
• Hands-on experience deploying ML models into production
• Exposure to cloud platforms (Azure and/or Databricks) and MLOps practices
• Excellent communication skills with the ability to influence non-technical stakeholders
• Comfortable working in fast-paced, cross-functional environments

Nice to have

Why apply?

• Work on real, business-critical data science problems with measurable impact
