Product Designer (Mobile Native B2C)

Description

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. As part of that, we're scaling Viber Pay, an integrated fintech offering that puts trusted payments, money movement and financial services into the hands of our users worldwide.

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. You'll be based in our London office, working closely with product and engineering in the UK, and day-to-day with our design team in Israel.

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
• The design decisions you make will directly affect how people send money, pay bills, and manage their finances. All inside an app they already use to talk to the people they care about
• 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. Build on what exists and bring new approaches to the team
• Help shape AI-driven product features in a super-app that is actively integrating AI into the user experience
• Conduct hands-on research: user interviews, usability tests, digging into data and analytics
• Contribute to and help evolve the design system shared across Viber products
• Stay connected to the bigger picture, how design decisions tie into product KPIs and business outcome

Requirements

• 5+ years of product design with some experience in B2C mobile products, ideally in fintech, payments, or digital wallets
• Someone who takes full ownership, from framing the problem to shipping, without waiting 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. Gets the details right: microcopy, edge cases, error states, micro-interactions. In fintech, the difference between good and great is often the 10% nobody talks about
• Experience designing regulated or compliance-adjacent flows, identity verification, onboarding, transaction limits, and making them feel human rather than bureaucratic
• Comfortable running your own research, giving and receiving honest feedback, and participating in team rituals, design critiques, and cross-location syncs with the team in Israel
• Clear communicator, in writing and in conversation, across product, engineering, and leadership
