ZetaChain is seeking an experienced Senior Product Designer to craft intuitive, high-impact consumer experiences across mobile, web, and platform surfaces. In this role, you’ll shape end-to-end product journeys, collaborate closely with cross-functional teams, and elevate the overall quality of everything we ship.

This is a hybrid position—we collaborate in person periodically (SF Bay Area preferred) while supporting remote teammates across U.S. time zones. Our team works pragmatically and experiment-driven, with a strong bias toward shipping quality and learning quickly. You’ll have significant ownership and tight feedback loops with Product, Engineering, Marketing, and Operations.

What You'll Do

Design consumer products end‑to‑end — from discovery and framing through flows, wireframes, high‑fidelity UI, prototypes, and specs.
Own mobile, platform, and web experiences across the product lifecycle (exploratory concepts → MVP → iteration and optimization).
Drive clarity with user journeys, information architecture, and design systems that scale across surfaces.
Prototype and validate — use interactive prototypes and qualitative/quantitative signals to inform decisions.
Partner closely with Product, Engineering, Marketing, and Operations to plan roadmaps, scope experiments, and ensure high‑quality execution.
Champion the user — advocate for usability, performance, and craft while balancing business and technical constraints.

Minimum Qualifications

3+ years of product design experience building shipped consumer products at scale.
Have led 0 to 1 design for commercial consumer products.
Portfolio of work demonstrating shipped products, strong interaction design, visual craft, and problem‑solving across mobile and web. (Please include a public portfolio link or case studies.)
Expertise in mobile app (iOS/Android) and web product design, with a solid grasp of responsive patterns.
Proficiency with Figma; comfort using AI tools (e.g., ChatGPT) for exploration and documentation.
Demonstrated ability to partner with cross‑functional teams and drive end‑to‑end outcomes.
Experience defining and contributing to design systems and UI standards.
Strong communicator with clear rationale, crisp documentation, and comfort presenting to executives and engineers.

Bonus Points

Experience working in high‑growth startups.
Familiarity with web3/crypto concepts and multi‑chain ecosystems (not a hard requirement).
Experience designing platform products (e.g., dashboards, developer/partner tools) alongside consumer flows.
Background in user research, experiment design (A/B), and funnel optimization.
