Data Scientist / ML Engineer (Data & AI)
- Experience: 3+ years
- English Level: Upper-Intermediate
- Location: Ukraine/Europe
Zipify builds high-impact Shopify apps that help merchants maximize revenue and conversion. Our flagship product, OneClickUpsell (OCU), has generated over $1.2B in upsell revenue for merchants. We are evolving beyond traditional SaaS into a hybrid model that combines product, AI, and high-value services to deliver measurable growth for ecommerce brands.
We’re looking for a Data Scientist / ML Engineer who is equally comfortable working with data and building AI-powered systems. This is not a role for someone who only trains models — we need someone who understands data end-to-end: from exploring and cleaning it, to building intelligent features on top of it. If you have a background in BI, data analytics, or data engineering and have grown into ML and AI — this might be a great fit.
