Responsibilities

• Own full-cycle mobile product design (onboarding, paywall/subscription, customization & shop, content modules): from hypothesis → research → UX/UI → handoff to development → measurable result.
• Build and grow a design system from scratch for iOS and Android as the foundation for fast, consistent releases.
• Design quiz funnels end-to-end — step flow, question layouts, interstitials, paywall — with efficient turnaround. 
• Turn product requirements into clear UX flows, user stories, UI screens, and interactive prototypes in Figma. 
• Run competitive UI/UX analysis and adapt the best solutions to business goals. 
• Work closely with PM, PMM, and engineers, defend design decisions, and iterate quickly. 
• Deliver clean, dev-ready handoff that keeps engineering moving.

Requirements

• 2+ years as a Product Designer
• Proven experience building a design system from scratch, not only working within an existing one. 
• Strong Figma with a systems mindset — components, auto-layout, variants, tokens, interactive prototypes. 
• Full-cycle product design experience: from hypothesis and research through UX/UI to handoff and measured results.
• Portfolio with conversion-driven flows (quiz funnels, onboarding, paywalls/subscription). 
• Mobile app design experience across iOS and Android patterns. 
• Good judgment on fidelity — matching effort to whether something is a test or a final release. 
• Solid visual craft: typography, hierarchy, consistency.

Would be a plus 

• Experience with subscription products in health/wellness or e-learning. 
• Experience in a growth/funnel team with regular A/B testing.
• Building reusable funnel templates or component kits.
• Motion / micro-interactions.
