Senior Machine Learning Engineer - Growth & Personalisation

What You'll Be Doing

• Build and improve ranking models for vertical landing pages (grocery, retail), deciding what a user sees first when they land on a store page
• Design models that blend new-vertical content into a homepage built around restaurant ordering, without disrupting the core experience
• Build personalisation models that translate a user's existing behaviour into relevant recommendations for verticals they haven't tried yet
• Contribute to notification targeting — who gets notified, with what message, and when, to drive adoption of new verticals

What You'll Need to Thrive

• Minimum 3+ years of experience as an ML Engineer or Data Scientist, with a proven ability to write high-quality production code in Python
• Experience with end-to-end model productionisation
• A bias to simplicity, where you care most about achieving impact
• Background in personalisation, ranking, or recommender systems; exposure to causal inference or uplift modelling is a genuine plus but not expected
