Senior Product Designer- Hardware (fixed term 12 months)

Own product design end to end for Solo, a hardware card reader used by millions of merchants. The role sits within the Solo squad, working across embedded systems, on-device UI, companion app, and backend, with real scope to shape how the next generation of Solo evolves.

What you'll do

• Own product design end to end for Solo: framing problems, running research, defining UX flows and information architecture, and delivering production-ready designs
• 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
• Make and explain design trade-offs against real technical constraints, without compromising product quality
• Partner with product to define success metrics tied to business goals, and use data to validate design decisions
• Evolve SumUp's global design system (Circuit UI) and the Solo hardware UI library, keeping a consistent design vision
• Share feedback and craft knowledge with the wider design chapter

What you'll need

• Extensive experience owning complex product design work independently, with deep expertise in either UX or UI and strong skills in the other
• Comfort defining multi step flows and information architecture, accounting for edge cases and dependencies across the user journey
• Fluency with common design and prototyping tools, particularly Figma
• A human centred design process, backed by both qualitative and quantitative research methods
• Ability to translate technical constraints into design trade-offs and document them clearly in specs
• Track record shipping complex products through a full development cycle in an agile environment

• Experience launching products in new or global markets, including localisation and multi screen considerations
