### **About Zeal:** Zeal is addressing the critical challenge of untapped transactional data. At the moment, whenever a transaction is processed on a POS terminal (payment card machine), physical retailers have no idea who the paying customer is, unless they use a loyalty program. Think of when you go to a supermarket and you pay by card, unless you go to a supermarket that has a loyalty program and you get your loyalty card out, the POS terminal doesn't tell the retailer if you're a new or returning customer, demographics, gender, etc. Unlike e\-ecommerce, in physical retail customer identification always had to be a separate step because the payment terminal is not built to self\-identify the paying customer. Hence, a plethora of valuable data is lost or underutilized. With Zeal's advanced Smart POS plugin, the company integrates with POS terminals globally to provide payment acquirers and ISVs with a unique differentiator for their POS terminals. The merchants of our partners benefit from world\-class data, analytics \& tools to predict consumer behavior using Artificial Intelligence, enabling merchants to unlock the full potential of transactional data. ### **About The Role:** We're looking for a **Backend Lead** to own the architecture, scalability, and technical roadmap for one of our squads within our backend ecosystem.
