• Help grow and shape the data science team and its role within the wider business.

What We’re Looking For

• Proven experience in deploying machine learning models or optimisation algorithms into production.
• Solid understanding of digital marketing concepts, platforms (e.g., Google Ads, Meta), and analytics tools.
• Demonstrated experience across key use cases such as:
