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.

• Own complex product features end-to-end — from understanding the problem and shaping the solution through implementation, launch, and iteration.
• Work closely with the product team to shape what we build, challenge assumptions, and turn ambiguous problems into great product experiences.
• Build polished, responsive product experiences using React and TypeScript.
• Prototype and iterate on interactions quickly, using code, design tools, and AI to find the right solution.
• Obsess over the details that make interfaces feel great: interaction, motion, responsiveness, loading states, transitions, and microinteractions.
• Build and evolve reusable frontend components and our design system, improving consistency without sacrificing flexibility.
• Proactively identify places where the existing product experience can be improved — and take ownership of improving them.
• Maintain a high bar for performance, accessibility, reliability, and frontend engineering quality.
