Senior Product Engineer, Frontend

We're looking for a Senior Product Engineer, Frontend to join the team building Zerion Wallet. In this role, you'll own product experiences end-to-end — from understanding the problem and shaping the interaction to implementation, launch, and iteration. We're looking for someone who combines strong frontend engineering skills with product judgment and an unusually high bar for design and craft. We care not only about whether something works, but how it feels to use — and you should be comfortable challenging a solution when the experience isn't good enough. We value strong ownership, attention to detail, and the ability to move fast without compromising product quality.
