The role sits within the Solo squad, working across embedded systems, on-device UI, companion app, and backend, so decisions made here shape a product experience unlike a typical app role.
Whoever joins will step into a well-established craft with real scope to shape how the next generation of Solo evolves, working directly with engineering to bring ideas from concept to something millions of merchants use daily.
</p> <h2>What you'll do</h2> <ul> <li> <p>Own product design end to end for Solo: framing problems, running research, defining UX flows and information architecture, and delivering production-ready designs</p> </li> <li> <p>Work across the full hardware experience (embedded, on-device UI, app, and backend), partnering with product management and engineering to reach the best solution for merchants</p> </li> <li> <p>Make and explain design trade-offs against real technical constraints, without compromising product quality</p> </li> <li> <p>Partner with product to define success metrics tied to business goals, and use data to validate design decisions</p> </li> <li> <p>Evolve SumUp's global design system (Circuit UI) and the Solo hardware UI library, keeping a consistent design vision</p> </li> <li> <p>Share feedback and craft knowledge with the wider design chapter</p> </li> </ul> <h2>You'll be great for this role if…</h2> <ul> <li> <p>Extensive experience owning complex product design work independently, with deep expertise in either UX or UI and strong.
