3) Mobile UI and UX ownership

• Lead end to end UX from user flows and wireframes to high fidelity UI, interaction states, and clickable prototypes.

• Design mobile first experiences for Android and iOS, including onboarding, dashboard, tasks, rewards, and account and security related screens.

• Create and maintain a scalable component library and design system in Figma, including gamification components and states.

• Produce developer ready specs, including layout rules, responsive behavior, empty states, error states, and accessibility considerations.

4) Cross functional delivery with engineering

• Work closely with engineers, QA, and product managers to plan, scope, and deliver features on schedule.

• Provide detailed handoff materials, including annotations, interaction rules, and acceptance criteria for UI behavior.

• Review builds, provide structured feedback, and ensure the shipped UI matches intended design and quality.

5) Web and website design support

• Support related web experiences when needed, including landing pages, product marketing flows, and partner portals.

• Ensure consistent brand expression and design language across mobile and web.

6) Testing, iteration, and metrics driven improvement

• Collaborate on usability testing and rapid iteration cycles to validate designs before and after release.

• Partner with product and analytics to monitor activation, retention, feature adoption, and reward engagement, then iterate based on data.

• Maintain documentation of design decisions, edge cases, and learnings to scale the system over time.
