We are looking for an experienced Senior/Lead Product Designer who can lead the full product design cycle — from discovery and research to prototyping, testing, and scaling solutions. In this role, you will be a key partner to product managers, developers, and analysts, shaping product strategy and creating solutions backed by metrics and measurable business results.

We expect candidates to be located in one of the following cities: Warsaw, Wroclaw, Lodz, Gdansk or Bialystok.

• Interface & Design System: Build accessible (WCAG-compliant) and scalable interfaces, maintain and evolve the design system, and ensure a consistent visual language across the product
• Product Impact: Demonstrate how design impacts key metrics (conversion, task completion time, retention, engagement). Showcase before/after case studies and argue ROI of design initiatives
• Cross-Functional Collaboration: Work closely with PMs, analysts, and engineers; facilitate design workshops and sessions; present solutions to stakeholders
