- Ensure UX consistency and quality, including design system adherence, responsive/mobile-first principles, accessibility, and edge-case handling.
- Define and enforce frontend testing, monitoring, and quality standards.
- Collaborate across teams to shape APIs, data flows, error-handling, and user flows for Earn features and DeFi integrations.
- Serve as a senior technical voice in architecture, tech-strategy, and long-term frontend planning.
