Senior UX Interface Designer

Key Tasks & Responsibilities

• Visual Design Leadership (Defining Responsibility)
• Own the overall aesthetic standard of the product: typography application, spatial rhythm, depth hierarchy, color restraint, icon quality, and component polish
• Ensure the product reads as a premium consumer tool — not a clinical health app, generic fitness tracker, or scaled-up spreadsheet
• Apply visual judgment to commercial surfaces (marketplace, subscription tiers, upsell moments) while maintaining trust in the system
• Build and maintain the authoritative Figma (or equivalent) design system: token library (colors, type ramps, spacing, radius, motion), component library, and identity cell documentation
• Identity-Driven & Personalized Experience Design
• Design the identity recoloring moment in onboarding as the signature emotional beat of the product — a real-time ambient palette transition that feels intentional, earned, and beautiful
• Design the shareable identity card in both quiet (clean, restrained) and expressive (gamified, bold numbers) aesthetic modes
• Ensure the primary dashboard identity symbols function coherently as both the user's visual identity expression and the entry point to the AI coaching layer
• Ensure scoring loops, streak mechanics, and progression tier displays feel motivating and identity-consistent — not a generic gamification model
• Motion Design & Interaction
• Design and spec all animated moments, including the readiness score arc animation, the pre-launch cinematic welcome experience, identity ambient recolor, mission/achievement completion states, AI coaching insight reveals, and score/pillar change reveals
• Define motion standards for the full product: screen transitions, micro-interactions, press states, loading states, skeleton screens, empty states, and error states
• Produce implementation-ready motion specs for multiple devices: Bodymovin/Lottie files, timing curves, duration values, and engineering handoff notes
• UX/UI Design Across the Full Screen Inventory
• Design action-oriented experiences that tell the user what to do next; every screen should have a clear direction rather than a passive display of data
• Translate complex biomarker, wearable, and AI-generated data into interfaces that are immediately readable and emotionally resonant — not dense, clinical, or overwhelming
• Design the dashboard priority engine as the product's daily engagement surface — one that feels like a coach, not a notification list
• Design an AI coaching modal as a distinct experience layer, and maintain high-fidelity designs across iOS, Android, and Web simultaneously (design once, build anywhere)
• Cross-Platform Consistency & Engineering Collaboration
• Ensure a unified visual and interaction experience across iOS, Android, and Web — respecting platform-specific behaviors without fracturing the design system

Education & Experience

• 5+ years of experience in UX/UI and product design, with at least 2 years designing for mobile (iOS/Android) at a consumer product company
• Must Demonstrate Understanding of color as a functional system communicating status, identity, causality, and trust
• Proficiency in Figma or equivalent — component libraries, auto-layout, design tokens, prototyping, and developer handoff
• Proficiency in motion/animation tools (Lottie, After Effects, Framer, or equivalent) with demonstrated ability to spec animations for engineering implementation
• Comfort with AI-assisted development tools such as Lovable, Cursor, or similar, and willingness to adopt new tooling quickly

Preferred Qualifications

• Experience designing for health, fitness, performance, or biomarker applications
• Experience designing consumer commerce surfaces in a trust-sensitive context, including in-app purchases, subscription tier presentations, or health/telehealth marketplaces
• Familiarity with React Native / Expo design constraints: safe areas, platform-specific scroll physics, gesture models, and native component behavior
• Light front-end knowledge (TypeScript, React Native, CSS) sufficient to assess implementation fidelity and communicate specific divergence from design intent
• Experience designing gamification and progression systems: achievement states, streak mechanics, leaderboard displays, tier progression
• Familiarity with identity-adaptive or multi-theme design systems: real-time palette shifts, persona-keyed visual treatments, multi-tier token management
• Experience with cinematic or motion-heavy product moments (brand launch surfaces, product reveal animations, celebration states) and demonstrated ability to art-direct sound, motion, and timing together
