Senior Product Design Engineer

<p style="min-height:1.5em">At Rohlik Group, we are building the future of e-grocery for over a million active customers across the Czech Republic, Germany, Austria, Hungary, and Romania. We own our entire technology stack — from storefronts and apps to automated fulfillment centers and last-mile logistics.</p><p style="min-height:1.5em">Within the Customer Experience (CUEX) domain, we own every touchpoint a customer interacts with, from the homepage to checkout and real-time order tracking across web, iOS, and Android. Our five storefronts run on a single product spine with localized content, pricing, and brand layers. We operate as a deliberately tight-knit, high-performing team where a Product Owner, Engineering Manager, Tech Lead, two Product Designers, and a dedicated full-stack engineering team ship fast, iterate constantly, and take full ownership of the end-to-end user journey.</p><p style="min-height:1.5em">Most interface failures in e-commerce aren’t layout issues — they are communication problems: what is said, in what order, and on which screen. As Senior Product Design Engineer, you will own the end-to-end design of all customer-facing surfaces across five markets. You will also manage our design system, Maia (our AI shopping assistant), and provide the design guidance that powers our automated coding workflows.</p><p style="min-height:1.5em"></p><h2>Why this role is exciting</h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>High-impact Group scope:</strong> Design every customer-facing touchpoint across web, iOS, and Android for five international markets, impacting millions of orders.</p></li><li><p style="min-height:1.5em"><strong>True end-to-end ownership:</strong> Lead the complete lifecycle of product design — from initial problem definition and customer research to shipped A/B tests and real-world performance analysis.</p></li><li><p style="min-height:1.5em"><strong>AI-first execution:</strong> Rohlik is an AI-first company.
