Description

SumUp is hiring a Senior Product Designer for the Sell Online team to work on products for small business owners. The role involves end-to-end design for Bookings and Online Store products, collaborating with cross-functional teams. The company offers opportunities for growth, diversity, and inclusion.

Responsibilities

Own end-to-end design across Bookings and Online Store products. Craft visually compelling interfaces, including iconography and illustrations. Work across multiple squads simultaneously, collaborating with product managers and engineers. Contribute to and evolve the design system. Use qualitative research and user data to inform design decisions.

Requirements

You have a strong portfolio demonstrating end-to-end product design — from wireframes and user flows to high-fidelity UI — with a clear emphasis on visual craft, typography, and layout. You have experience designing for customer-facing products on both web and mobile, ideally in e-commerce, bookings, or similar consumer contexts. You have proven ability to work with and contribute to design systems at scale. You are comfortable with managing multiple workstreams and stakeholders across different product areas at the same time. You have a collaborative, curious mindset — someone who listens well, adapts quickly, and can navigate ambiguity without losing momentum.

Conditions

Work from vibrant Warsaw office. Virtual Stock Option programme. Annual L&D budget of €2000. Fitness support and health insurance. 26 days paid leave plus public holidays. 1-month sabbatical after 3 years. Referral Bonus.
