Salary range: 15 600 - 27 000 PLN per month

Senior Product Designer – Sell Online

About the team

The Sell Online team builds the products that help small business owners run and grow their businesses online — from appointment bookings and online stores to customer management. We're a cross-functional design team embedded across multiple product squads, working closely with product managers and engineers to shape experiences used by millions of merchants worldwide. As we expand our portfolio and grow our engineering capacity, we're looking for a Senior Product Designer who can bring strong visual craft, product thinking, and the confidence to own complex design challenges across several product areas simultaneously.

What you'll do

• Own end-to-end design across our Bookings and Online Store products — from early-stage concepts and user flows through to polished, high-fidelity UI ready for development


• Craft visually compelling interfaces, including iconography and illustrations, that raise the bar for quality and consistency across the portfolio


• Work across multiple squads simultaneously, collaborating closely with product managers, engineers and other designers to keep design and delivery in sync


• Contribute to and evolve our design system, ensuring consistency and scalability as the product portfolio grows


• Use qualitative research and user data to inform design decisions and validate solutions — bringing a user-centred lens to everything you ship

You'll be great for this role if…

• 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
