Rakuten Viber is one of the most popular and downloaded apps in the world. Working with us is a chance to influence hundreds of millions of users and be part of the journey that makes us a super-app. Our mission is to make people's lives easier by enabling meaningful connections, from precious moments with family and friends, through managing business relationships to pursuing their passions. We're looking for an experienced Product Designer with strong craft, a data-driven instinct, and a genuine curiosity for how things work. This is an end-to-end role from discovery to delivery, on a product that handles people's money and trust. Why this role is different: You're joining a design team that is genuinely rethinking how it works with AI, and already putting it into practice You'll work in a real feedback culture with short loops between design, product, and leadership. A manager who runs 1:1s focused on your growth and expects you to drive it yourself. Responsibilities Lead the full design process: discovery, research, prototyping, testing, final design Own the design for financial flows where clarity and trust aren't optional. Sending and receiving money, wallet onboarding, transaction history, identity verification Use AI tools actively across your work, research synthesis, ideation, prototyping, workflow automation.

You're always looking for what's next Someone who takes full ownership, from framing the problem to shipping, without needing to be told what to do next Leads with data: digs into data and analytics independently, understands the metrics behind a feature before jumping to solutions Strong UX foundation with real attention to detail. Get the details right: microcopy, edge cases, error states, micro-interactions.
