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.

What We Value in a New Master

• 3+ years Python hands-on experience with pandas and NumPy.
• Strong SQL skills — writing complex queries, working with nested and JSON data structures, query optimization, and understanding of normalization principles.
• Experience with EDA, data quality, and working with messy real-world data.
• 1+ years of ML experience: classification, clustering, regression — and hands-on experience building such models.
• Experience working with LLM APIs and prompt engineering.
• Understanding of how to design and build practical agentic systems.
• Understanding of agentic system design.
• Git, Docker — comfortable day-to-day usage.
• English level: Upper-Intermediate or higher.
