• Python
• AWS stack – Glue, Lambda, S3, EC2, Jupyter
• Power BI or Tableau (bonus)
• Excel (PowerPivot, VBA, lookups, advanced formulas)

You’ll also:

• Collaborate closely with our Data Engineers and Product Owner
• Own your solutions end-to-end, from design through deployment
• Help ensure clean, scalable, and well-tested code
• Drive automation that saves time and cost across the business
• Contribute to a data culture where quality, collaboration, and impact come first

What you bring:

• 2+ years of hands-on experience with large relational databases (500K+ customers)
• Deep knowledge of relational database concepts and performance optimisation
• Strong SQL and Python skills
• Experience designing in cloud environments — ideally AWS
• A collaborative mindset and the ability to translate business needs into technical specs
• Bonus: knowledge of BI tools, domain experience in retail/marketing/loyalty, or a background in a quantitative discipline
